	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java:
	  Added kludge for the types of artifact data. They seem to be null
	  in some circumstances. Needs to be debugged!

2011-07-31  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/datacage/DBConfig.java:

	  Added some debug output.

2011-07-29  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/datacage.sql: Removed artifact_id from facet because there
	  is a link via out_id -> outs.id: artifact_id -> artifacts to
	  find the corresponding artifact.

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java,
	  src/main/resources/datacage-sql/org-h2-driver.properties: Store
	  facets of outs into datacage db at initial scan.

2011-07-29  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java,
	  src/main/resources/datacage-sql/org-h2-driver.properties:
	  Store outs of artifacts into datacage db at initial scan.
	  TODO: store facets.

2011-07-29  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/datacage.sql: Added 'type' column in artifacts data.
	  Maybe useful for filtering.

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java,
	  src/main/resources/datacage-sql/org-h2-driver.properties:
	  Store artifact data into db at initial scan.
	  TODO: store outs and facets.

2011-07-29  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java,
	  src/main/resources/datacage-sql/org-h2-driver.properties:
	  Add artifacts into datacage db at initial scan.
	  TODO: Store data, outs and facets.

2011-07-28  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/datacage.sql: Fixed spelling in sequence name.

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java,
	  src/main/resources/datacage-sql/org-h2-driver.properties: Simply add
	  collection item at initial scan if artifact was stored before.
	  TODO: Store new artifacts.

2011-07-28  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java,
	  src/main/resources/datacage-sql/org-h2-driver.properties: Add
	  collections at initial scan.

2011-07-28  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java,
	  src/main/resources/datacage-sql/org-h2-driver.properties: Add users
	  at initial scan.

2011-07-28  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/datacage.sql: Using sequences for id generation now
	  to make schema more compatible.

2011-07-28  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java,
	  src/main/resources/datacage-sql/org-h2-driver.properties: Clear database
	  before initial scan.

2011-07-28  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/datacage/DBConnection.java:
	  Deleted. This stuff comes from the artifact database now.

	* src/main/java/de/intevation/flys/artifacts/datacage/DBConfig.java:
	  New. The db config of the datacage database.

	* src/main/resources/datacage-sql/org-h2-driver.properties: New.
	  The SQL statements needed for the datacage.

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java:
	  Make use of the db config.

2011-07-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java:
	  New. A artifact database lifetime listener to build the initial
	  index of the artifacts in database.

	* doc/conf/conf.xml: Added the datacage to the list of lifetime
	  listeners.

2011-07-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/datacage.sql: Added an explicit table for the outs
	  of an artifact.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Make the current outs of an artifact accessible only with
	  the global context.
	
2011-07-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/datacage.sql: Added ON DELETE CASCADE constraints.
	  Added state in facet.

2011-07-26  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/datacage.sql: New. H2 Schema for the datacage database.
	  Uses special features like IDENTITY (autoincrement) typed columns.

	* src/main/java/de/intevation/flys/artifacts/datacage/DBConnection.java:
	  Pooled connection.

	* pom.xml: Added dependencies to H2 and Apache DBCP.

2011-07-26  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/test/java/de/intevation/flys/artifacts/AppTest.java,
	  src/main/java/de/intevation/flys/artifacts/App.java: Removed.
	  This the stupid "Hello, World!" app initially created by the
	  maven archetype. It was never used.

2011-07-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
	  Argh! Usage the DOM was not thread safe (discovered with ab).

2011-07-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/meta-data-template.xml: '$recommended' lead to XPath
	  errors. Using "dc:contains($parameters, 'recommended')" helps.

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java,
	  src/main/java/de/intevation/flys/artifacts/services/meta/FunctionResolver.java:
	  Added some debugging.

	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
	  Added parameters as 'parameters' to parameters. Usefull to check
	  for containment of variables.

2011-07-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Added 'if log.isDebugEnabled() {}'.

2011-07-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Made Artifact UUID optional and accept extra parameters, too. This enables
	  the service to be used without an arttifact and test all filters.

	  <art:meta xmlns:art="http://www.intevation.de/2009/artifacts">
	     <art:outs value="computed_discharge_curve,floodmap"/>
	     <art:parameters value="river:Elbe"/>
	     <art:filters value="recommended"/>
	  </art:meta>

	* src/main/java/de/intevation/flys/artifacts/services/meta/FunctionResolver.java:
	  'contain' accept Maps and collection, too.

	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
	  Made artifact option (= null) in recommendations.

2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/CompiledStatement.java:
	  Moved connection specific into inner class. The enables the reuse of the
	  compiled statement.

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java: The
	  SQL statements are now only compiled once at creation time of the builder.
	  Each connection now reuses them.

2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/cache.xml: Added configuration for static datacage db access.

	* src/main/java/de/intevation/flys/artifacts/services/meta/App.java: Using
	  caches seems to need an explicit System.exit().

	* src/main/java/de/intevation/flys/artifacts/services/meta/CompiledStatement.java:
	  Added support for caching the SQL statements and there results.

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java: Some
	  clean up. Reordered code for performance. Strip SQL statements more
	  aggressively.

	* src/main/java/de/intevation/flys/artifacts/services/meta/ResultData.java:
	  Made it Serializable.

	* src/main/java/de/intevation/flys/artifacts/cache/CacheFactory.java:
	  Introduced system property 'flys.artifacts.cache.config.file' to make
	  the caching configurable without pulling up the whole stack.

2011-07-22  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Prepared the FLYSArtifactCollection to support the storage of already
	  loaded recommendations in its attribute document.

2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Adjusted to use the DataCage recommendations. The incomming document
	  can pass the artifacts UUID by '/art:outs/@value' the outs as a
	  comma separated list in '/art:outs/@value' and optional a set of
	  filters comma separated in '/art:filters/@value'.

	  If UUID and OUTS are not given the old service is used. This
	  should be removed as soon as the client uses the new service.

2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/CompiledStatement.java:
	  Allow '-' in variable names.

2011-07-21  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/meta-data-template.xml: Now, the river-id is really added to
	  the factory node of the wmsbackground layer.

2011-07-21  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/meta-data-template.xml: Added the river-id to the factory node
	  of the riveraxis and wmsbackground layer.

2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java,
	  src/main/java/de/intevation/flys/artifacts/services/MainValuesService.java,
	  src/main/java/de/intevation/flys/artifacts/services/DistanceInfoService.java,
	  src/main/java/de/intevation/flys/artifacts/services/RiverService.java:
	  Adjusted to implement changed Service interface.

2011-07-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Refactored
	  the method that retrieves the Outputs for the Artifact. Now, we are able
	  to query the Outputs for the current state, and all outputs separately.

	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java: The
	  recommendations provided by this monitor will take the Outputs of the
	  current state only into account.

2011-07-21  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/meta-data-template.xml: Added conditions for each output type.
	  Splitted the "floodmap" output into two parts: a recommended one and a
	  complete one. The recommended part will only build the document tree for
	  the recommended artifacts; the complete part will build the whole document
	  tree that is available for a floodmap.

	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java:
	  This Hook now uses the DataCage to generate the recommended artifacts.
	  The output-defaults configurtion is needless now.

	* doc/conf/output-defaults.xml: Removed. The configuration of recommended
	  artifacts takes place in meta-data-template.xml.

	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
	  Bugfix: the DataCage didn't start working if its builder was NOT null,
	  but it shouldn't start if the builder IS null.

2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
	  Now it is possible to directly pass a Node as a root to the builder.
	  The owning document if fetch by Node.getOwnerDocument(). This is
	  useful if you want to generate the recommendation directly into
	  an already existing document under a given node.

	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
	  Changed the signature of recommend() to accept a node where to
	  append the recommendations.

2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
	  Added a macro mechanism:

	    <dc:macro name="keine-fuenf">
	      <dc:text>'5' ist nicht in der Liste der Outs.</dc:text>
	    </dc:macro>
	    <dc:call-macro name="keine-fuenf"/>
	    <dc:call-macro name="keine-fuenf"/>
	    <dc:call-macro name="keine-fuenf"/>

	  Macros can be defined everywhere in the template
	  with 'macro'. There bodies can contain all valid elements
	  including other 'macro's and 'call-macro's. They are
	  called with their 'name' with 'call-macro'. The control flow
	  is continued inside the body of the called macro and 
	  will continue right after the calling 'call-macro' when
	  the macro body is finished.

2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
	  Added a new 'if' construct similiar to XSLT:

	    <dc:if test="not(dc:contains($outs, '5'))">
	        <dc:text>'5' ist nicht in der Liste der Outs.</dc:text>
	    </dc:if>

	  The control flow is continued inside the 'if' if the 'test' attribute
	  as an XPath expression on an empty document evalutes to true.
	  Else the inside is skipped. There is no 'else'. Use 'choose'/'otherwise'
	  if you need this.

2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
	  Added a recommend() method to generate recommendations for
	  a given artifact, outs and extra parameters.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added
	  method to extract all data at once.

2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/FunctionResolver.java:
	  New. Custom XPath function provider. Provides
	  'dc:contains(Object [] haystack, Object needle)' by now. Should be
	  useful to check containments in 'out' lists later.

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
	  Register the FunctionResolver to the evaluated XPaths.

	* src/main/java/de/intevation/flys/artifacts/services/meta/App.java:
	  Added code to parse
	  "param:a,b,c" to "param" -> new String [] { "a", "b", "c" } to
	  help testing the 'dc:contains' XPath function.

2011-07-20  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: Added wms configurations for Saar, Mosel and Elbe.
	  Each river supported by FLYS requires such a WMS configuration. A WMS
	  should contain layers for the river axis, buildings, kilometer labels
	  and maybe a background layer as well.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java:
	  Added key that is used to store a map of WMS URLs - for each river a
	  WMS URL.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  Parse the river WMS from global configuration.

	* src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java:
	  Create WMSLayerFacets with URLs based on the river and the river wms
	  configuration stored in the FLYSContext.

	* src/main/java/de/intevation/flys/artifacts/WMSBackgroundArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/RiverAxisArtifact.java:
	  Adapted the initialize() signature and the method call of computeInit()
	  which requires a FLYSContext to retrieve the river WMS configurations.

	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java,
	  src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added the context object parameter to the computeInit() method.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Call
	  initialize() with the context object - which is a FLYSContext or a
	  CallContext.

2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/App.java:
	  Check if builder was created properly before using it.

	* src/main/java/de/intevation/flys/artifacts/services/meta/StackFrames.java:
	  Implements now variable provider for XPath expressions.
	
	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
	  Added new choose/when/otherwise construct similiar to XSLT

	      <dc:choose>
	         <dc:when test="$river = 'Mosel'">
	             <dc:text>Es ist die Mosel.</dc:text>
	         </dc:when>
	         <dc:when test="$river = 'Saar'">
	             <dc:text>Es ist die Saar.</dc:text>
	         </dc:when>
	         <dc:otherwise>
	            <dc:text>Es ist weder Mosel noch Saar.</dc:text>
	         </dc:otherwise>
	      </dc:choose>

	  A 'choose' block can contain a list of 'when's and an optional
	  'otherwise'. For each 'when' the test attribute is evaluated
	  as an XPath expression on an empty document. The result of
	  the evaluation is taken as a boolean value. If its value is
	  true the control flow is continued inside the corresponding
	  'when' and the other choose elements are not tested.
	  If the value is values the testing continues with the next
	  'when'. If no 'test' expression is evaluated to true, the
	  control flow continues inside the 'otherwise'. If no 'otherwise'
	  is given nothing happens at all.

2011-07-20  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: Added a config section for floodmaps. Currently, the
	  background layer's url and layername is defined here.

	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java:
	  Read the background layer configuration from conf.xml. Those values are
	  used to create the WMSLayerFacet.

2011-07-20  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java:
	  The background layer facet will no longer have an extent set.

2011-07-20  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java,
	  src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java:
	  Set the extent of the created WMSLayerFacets and i18n its descriptions.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_de_DE.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Added I18N strings for the
	  background an river axis layer.

2011-07-20  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WMSLayerFacet.java:
	  This facet type has a method to set the extent of a WMS layer. The
	  extent is written to the facets XML node in toXML() as well.

2011-07-20  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Adapted
	  the signature of setup() which requires a CallMeta parameter now.

	* src/main/java/de/intevation/flys/artifacts/WMSBackgroundArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/RiverAxisArtifact.java: Use
	  the CallMeta object retrieved in setup() to call initialize(). It is now
	  able to i18n things.

2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/App.java: New.
	  Standalone app to debug the datacage template. To use in a maven environment:

	  -Dmeta.data.template=PATH_TO_META_DATA-TEMPLATE.XML \
	  -Dmeta.data.parameters=river:Mosel \
	  -Dmeta.data.output=OUTPUT.XML \
	  -Dflys.backend.user=DB_USER \
	  -Dflys.backend.password=DB_PASSWORD \
	  -Dflys.backend.url=DB_CONNECTION_URL \
	  -Dexec.mainClass=de.intevation.flys.artifacts.services.meta.App

2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
	  New. First step to factor out the "Datenkorb" logic into a service independent
	  singleton.

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Uses the "Datenkorb" singleton now.

2011-07-20  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacet.java:
	  Removed "index" property, because it is already existing in parent
	  class.

2011-07-19  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Improved error handling.

2011-07-19  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/resources/metadata/template.xml: Deleted.

	* doc/conf/meta-data-template.xml: New. Was template.xml

	* doc/conf/conf.xml: Made meta data template configurable.

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Load template from configuration not from resources.

2011-07-19  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/resources/metadata/template.xml: s/[a-z]+-id/db-id/
	  Make database ids identifiable with unique name "db-id".

2011-07-19  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacet.java:
	  Override the toXML() method. Subclasses can now write their own XML
	  representation.

	* src/main/java/de/intevation/flys/artifacts/model/ManagedDomFacet.java:
	  New. This ManagedFacet uses an Element (DOM) to store the information
	  about a facet. The intent of this facet type is to represent a facet
	  stored in an Collection attribute. Different facets can have different
	  attributes that we need to parse, but the only thing ManagedFacets need
	  to do, is to adjust the attributes "active" and "position". So, those
	  values are set directly on the Element, the other attributes aren't
	  touched.

	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacetAdapter.java:
	  New. This facet is a wrapper for another facet. This subclass of a
	  ManagedFacet overrides the toXML() method. The XML representation is
	  defined by the inner facet that is stored as member variable. The
	  ManagedFacet specific attributes "artifact", "facet", "pos" and "active"
	  are added manually.

	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: Uses
	  the toXML() method to write a facet node into the attribute document.

	* src/main/java/de/intevation/flys/collections/AttributeParser.java: Uses
	  the ManagedDomFacet to save the information of a facet which is
	  contained in the attribute part of a Collection's DESCRIBE document.

	* src/main/java/de/intevation/flys/collections/OutputParser.java: Uses the
	  ManagedFacetAdapter to save a facet, because we want to keep the
	  specific facet to be able to write its specific XML representation into
	  the Collection's DESCRIBE document.

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Adapted the XPath of facets stored in the attribute part of the
	  DESCRIBE.

2011-07-18  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added a
	  method that returns the Outputs for the Artifact.

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Adapeted the call of OutputParser.

	* src/main/java/de/intevation/flys/collections/OutputParser.java:
	  Simplified the code to read the Outputs of Artifacts. This parser will
	  now longer parse the DESCRIBE documents of the Artifacts, but query the
	  Outputs via FLYSArtifact.getOutputs() directly.

2011-07-18  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/StaticFLYSArtifact.java:
	  Adapted the function call of ProtocolUtils.appendOutputModes().

	* src/main/java/de/intevation/flys/artifacts/model/WMSLayerFacet.java:
	  Override toXML() to add the URL and layernames to the XML representation
	  of this facet.

2011-07-18  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/wmsbackground.xml,
	  doc/conf/artifacts/riveraxis.xml: New configurations for an Artifact
	  that is used as background layer in floodmaps, and an artifact that is
	  used as layer showing the river axis in a floodmap.

	* doc/conf/output-defaults.xml: New file to configure default artifacts
	  for specific output states. E.g. the floodmap state recommends a
	  background layer and a layer displaying the river axis. In suche case,
	  the floodmap state recommends two artifacts for the two layers.

	* doc/conf/conf.xml: Added new artifacts/artifact-factories and a Hook to
	  monitor artifacts (-> CollectionMonitor.java).

	* src/main/java/de/intevation/flys/artifacts/model/WMSLayerFacet.java:
	  New. This facet is used to represent a layer in a map. So, this facet
	  stores information about a WMS URL and the layer names provided by this
	  WMS.

	* src/main/java/de/intevation/flys/artifacts/model/FacetTypes.java: Added
	  facet types for the wmsbackground and riveraxis.

	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java,
	  src/main/java/de/intevation/flys/artifacts/WMSBackgroundArtifact.java:
	  New. An artifact and its default state. The intent of these classes is
	  to generate WMSLayerFacets which represent background layers in maps.

	* src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java,
	  src/main/java/de/intevation/flys/artifacts/RiverAxisArtifact.java: New.
	  An artifact and its default state. The intent of these classes is to
	  generate WMSLayerFacets which represent layers that display a river
	  axis.

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added the INIT ComputeType.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added a
	  case for the INIT ComputeType while computing data.

2011-07-18  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added a method computeInit() which is called to initialize data/facets
	  after an artifact has been created.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Repaired
	  broken XPath.

2011-07-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java:
	  Removed the code to generate new artifacts. Instead of creating new
	  artifacts automatically, we decided to suggest creating new artifacts
	  from specific types. Therefore, the DESCRIBE document of the artifacts
	  is extended with a node that contains recommended artifact types.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  FLYSArtifacts might be setup with the identifier of an other
	  FLYSArtifact. Subclasses are able to override a method called
	  initialize(Artifact, GlobalContext). This might be helpful to extract
	  required values or clone artifacts.

2011-07-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  Adapted the signature of createArtifactContext() - it returns an
	  instance of GlobalContext now.

2011-07-14  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/geom/Lines.java:
	  Debugged the water fill algorithm. Added a lot of logging.

	* src/main/java/de/intevation/flys/artifacts/charts/CrossSectionApp.java:
	  Added a text field to give a water level to fill in.

2011-07-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Moved code
	  to create the output modes based on the given facets to FLYSArtifact. In
	  addition, FLYSArtifact got a new method that returns a specific input
	  value as string.

	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java: New.
	  This hook monitors the "post-feed" and "post-advance". If the monitored
	  Artifact's state has configured recommended artifacts, this hook will
	  create new Artifacts.

	  TODO: We have to add the UUIDs of the new Artifacts to the DESCRIBE
	  document of the artifact to let the client know, that there are new
	  recommended Artifacts.

	* src/main/java/de/intevation/flys/artifacts/StaticFLYSArtifact.java: New.
	  This Artifact is the base class for Artifacts, that represent static
	  data. E.g. this could be a decoration theme in a chart or a background
	  layer in the map.

	* src/main/java/de/intevation/flys/artifacts/states/OutputState.java: New.
	  This state might be used as base class for states, that doesn't require
	  any user input, but only provide static Facets added by a computeFeed()
	  operation. So, subclasses need to implement computeFeed() only.

2011-07-13  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/charts/CrossSectionApp.java:
	  New. Standalone Swing-App to test cross sections from database without the
	  hassles of our complete software stack. Runnable from a maven environment:

	  $ mvn -e \
	    -Dflys.backend.user=DB_USER \
		-Dflys.backend.password=DB_PASSWD \
		-Dflys.backend.url=DB_CONNECTION_URL \
		-Dexec.mainClass=de.intevation.flys.artifacts.charts.CrossSectionApp \
		exec:java

	  You can set the river to be used with the system property 'river'.
	  Defaults to 'Mosel'.

	* src/main/java/de/intevation/flys/artifacts/model/WSPLGENFacet.java:
	  Removed superfluous imports.

2011-07-13  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: The FloodMapState has a new Outputmode
	  called "floodmap" now.

	* src/main/java/de/intevation/flys/artifacts/model/WSPLGENFacet.java: New.
	  This facet is used to generate WSPLGEN results.

	* src/main/java/de/intevation/flys/artifacts/model/FacetTypes.java: Added
	  the WSPLGENFacet.

	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
	  This state will now generate WSPLGENFacets.

2011-07-12  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/geom/Lines.java:
	  Fixed corner case.

2011-07-11  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/geom/Lines.java: New.
	  fillWater() generates a list of wet lines for a given profile and a
	  given water level.

2011-07-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  Outputs created while generating the DESCRIBE document will now have the
	  'type' member set.

	* src/main/java/de/intevation/flys/collections/OutputParser.java: Read the
	  'type' member from DESCRIBE document.

2011-07-06  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Removed a typo.

2011-07-06  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DataFacet.java:
	  DataFacet are now able to store the ID of the state which has created
	  this Facet.

	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java:
	  Initialize DataFacets with the ID of this state. This is necessary to
	  renew the waterlevel data if it is no longer existing in the cache.

2011-07-06  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/ReportFacet.java: A
	  report facet can now store the state's id and the artifact's hash value
	  when it has been created.

	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java:
	  Initialize the ReportFacet and WaterlevelFacet with state id and hash
	  information. This has been necessary to retrieve reports and waterlevels
	  in states after this one - in states that we need to enter for floodmap
	  parameterization.

2011-07-05  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelGroundDifferences.java:
	  Changed the desired UI provider.

2011-07-05  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Added the option to continue the
	  waterlevel parameterization with the intent to create flood maps.

	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java:
	  This state is no longer a final state. The user has the option to
	  continue with the parameterization for flood maps based on the current
	  waterlevel. Therefore, this states desires the "continue" UI provider.
	  Clients should recognice this to just step to the next state or display
	  a button that lets the user step to the next state manually.

	* src/main/java/de/intevation/flys/artifacts/states/FloodplainChoice.java,
	  src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java,
	  src/main/java/de/intevation/flys/artifacts/states/ScenarioSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/DGMSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/ProfileDistanceSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/WaterlevelGroundDifferences.java:
	  New. These states are used to parameterize a further calculation type:
	  flood map.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_de_DE.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Required strings for the
	  flood maps states.

2011-07-04  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	Fix(?) for flys/issue114

	* src/main/java/de/intevation/flys/artifacts/model/WQ.java:
	  Make guessing a bit more robust.

2011-07-03  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	Added the math needed to calculate "W-Differenzen" in "Laengsschnitten".
	Needs testing!

	* src/main/java/de/intevation/flys/artifacts/model/NamedObject.java:
	  Made it an interface to be usable in more than one inheritance chain.

	* src/main/java/de/intevation/flys/artifacts/model/NamedObjectImpl.java:
	  Implements the NamedObject interface and is the new base class of
	  WQ and WKmsImpl.

	* src/main/java/de/intevation/flys/artifacts/model/WKms.java:
	  New. Interface to associate kms with ws.

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java:
	  Changed the base class to NamedObjectImpl. Renamed getKms(int)
	  to getKm(int) to make clear it return a single scalar value
	  and fullfil the WKms interface.

	* src/main/java/de/intevation/flys/artifacts/model/WKmsImpl.java:
	  New. Implements the WKms interface. Intended to be a lightweight
	  datastore for "zusaetzliche Laengsschnitte" and as results
	  of the WKmsOperations.

	* src/main/java/de/intevation/flys/artifacts/model/WQ.java:
	  Changed base class to NamedObjectImpl.

	* src/main/java/de/intevation/flys/artifacts/math/WKmsOperation.java:
	  New. Operations on WKms data.
	  Currently only the SUBTRACTION operation is implemented. This
	  one is needed to calculate the "W-Differenzen". The operation
	  is insensitive about the km directions of the datasets. Missing
	  values are interpolated linear.

	* src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionGenerator.java,
	  src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  Adjusted to satisfy the signature change of WQKMs.

2011-07-01  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/StyledXYSeries.java: New. This
	  XYSeries stores the style information that should be used to render this
	  series. These information are stored as raw XML documents. A public
	  method can be used to apply those style information to a
	  XYLineAndShapeRenderer.

	  Note: The only two attributes currently supported by StyledXYSeries
	  items are "linesize" and "linecolor".

	* doc/conf/themes.xml: Added some more basic themes for the four
	  calculation methods.

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: This
	  generator now tries to apply themes for all series contained in the
	  chart. If a series is no instance of StyledXYSeries, the default
	  renderer is used.

	* src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionGenerator.java,
	  src/main/java/de/intevation/flys/exports/DurationCurveGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java,
	  src/main/java/de/intevation/flys/exports/ComputedDischargeCurveGenerator.java,
	  src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  Removed the code that had been introduced to adapt renderers statically.
	  Now, each of these concrete ChartGenerators instantiates StyledXYSeries
	  items to put the curves into the chart. Those items contain style
	  information now!

2011-07-01  Ingo Weinzierl <ingo@intevation.de>

	flys/issue135 (Diagramm: Trotz abgeschalteter Themen bleiben Beschriftungen bestehen)

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: The way
	  to store datasets has changed. Until this revision, the concrete
	  generators managed their own datasets. E.g. the
	  DischargeLongitudinalSectionGenerator had three datasets: w, q and
	  corrected w. Now, there are just two datasets, managed by this base
	  generator - one dataset for the first Y axis and one dataset for the
	  second Y axis. This makes it easier to remove axes, that have no data to
	  be displayed. All concrete chart generators have to add their XYSeries
	  using two methods: addFirstAxisSeries() and addSecondAxisSeries().

	* src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionGenerator.java,
	  src/main/java/de/intevation/flys/exports/DurationCurveGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java,
	  src/main/java/de/intevation/flys/exports/ComputedDischargeCurveGenerator.java,
	  src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  Those concrete chart generators no longer manage datasets themself but
	  they use the two methods described above, to plot the data to the first
	  or second Y axis.

2011-07-01  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/DistanceInfoService.java:
	  Added the option to use a filter to reduce the number of items returned
	  by this service.

2011-06-30  Ingo Weinzierl <ingo@intevation.de>

	flys/issue159 (WINFO: Radiobutton - Ortsauswahl bei "W für ungleichwertigen Abflusslängsschnitt" entfernen)

	* doc/conf/artifacts/winfo.xml: Changed the kilometer range input for
	  calculation 4. This calculation type requires a kilometer range. So,
	  after choosing the calculation 4, the transition model leads to a state
	  that just allows the input of a kilometer range with no option to
	  enter locations.

	* src/main/java/de/intevation/flys/artifacts/states/ComputationRangeState.java:
	  New. A base state for the kilometer selection for calculations. The
	  target of this state is to provide facets for the duration curves.

	* src/main/java/de/intevation/flys/artifacts/states/DistanceSelect.java:
	  New. This state is used to enter a kilometer range. The difference to
	  the LocationDistanceSelect state is, that there is no option to enter
	  locations.

	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java:
	  Improved this state to be the base state for calculation ranges.

	* src/main/java/de/intevation/flys/artifacts/states/LocationSelect.java
	  src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java

	* src/main/java/de/intevation/flys/artifacts/states/WQSelect.java: This
	  state no longer inherits from RangeState which now is used as base
	  state for kilometer ranges.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_de_DE.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Added new i18n strings for
	  the DistanceSelect state.

2011-06-28  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* pom.xml: Downgraded Trove to 1.1-beta-5, because the new
	  later ones are removed from the maven repos.

	  The functionality we need is in 1.1 so this downgrade should
	  cause no problems.

	  Would be nice if we would support the maintainers of trove to 
	  bring there new versions back into the main maven repos.

2011-06-28  Ingo Weinzierl <ingo@intevation.de>

	* pom.xml: Repaired the JBoss repository which place has changed.

2011-06-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/WaterlevelExporter.java,
	  src/main/java/de/intevation/flys/exports/WstWriter.java:
	  Append the corrected W column (if existing) to the WST export.

2011-06-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQ.java:
	  Guessing increaing w is not based on direct neighbors any more.
	  The second to be compared with is choosen by random of
	  the values before the first one. This makes the guessing
	  more robust against 'plateaus' of equal w values.

2011-06-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/exports/ATWriter.java: Array
	  for constructing the spline was too large leading to non-increasing
	  values.

	  Invert the x axis if its guessed that water is increasing.

2011-06-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQ.java(guessWaterIncreasing):
	  Added a method to guess based on a given factor of the size (default 0.05)
	  if the water levels are increasing. Needed to determine in which direction
	  the water level curve should be orientated. Based on random to avoid
	  running over large dataset each time a diagram is generated.

	  flys/issue177 (WINFO: Abflusskurven am Pegel verursachen ein Hängen des Servers)

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Commented out code to generate time ranges for series names. There
	  seems to be a problem while loading the discharge tables of a gauge or
	  while determining the start and/or end time of such discharge tables.

2011-06-26  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/**/*.java: Removed trailing whitespace.

2011-06-26  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Removed dead code.

2011-06-26  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	Fix for flys/issue173

	* src/main/java/de/intevation/flys/artifacts/model/Calculation4.java:
	  Fixed the way the gauge was found for a given interval.
	  The old way does not work because it was just tested if
	  the station point was inside the segments which is not
	  necessarily true. The obvious solution to simply check
	  the overlapping intervals does not work either because
	  the gauge ranges touch each other and so more than
	  one gauge are returned in these cases. The River.maxOverlap()
	  is now used to find the gauge with the max overlapping
	  range.

2011-06-26  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	Fix for flys/issue147

	* src/main/java/de/intevation/flys/artifacts/model/Calculation1.java:
	  Removed the 'kmUp' flag. It was an left over from former
	  WSP calculations (w/o ref km) leading to wrong results now.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Don't pass the kmUp flag to the calculation.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Added debug output to see the value of 'wq_free'.

2011-06-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Conversion w->q was broken. This should fix a number of issues
	  around "W am Pegel" calculations.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Issue an error report if a w->q conversion fails.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  The gauge to convert w->q with its discharge table was determined wrong.

2011-06-23  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* doc/conf/artifacts/winfo.xml, doc/conf/conf.xml:
	  Added facet config for AT exports.

	* src/main/java/de/intevation/flys/artifacts/model/FacetTypes.java:
	  Added 'at' facet type.

2011-06-23  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/exports/ATExporter.java: New.
	  Exporter for AT facets. Needs testing.

2011-06-23  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/exports/ATWriter.java: New.
	  Writer for AT files. New code because our data model differs
	  from Desktop-FLYS. Needs testing.

	  flys/issue157 (Diagramm: Ursprung berechnete Abflusskurve)

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java,
	  src/main/java/de/intevation/flys/exports/ComputedDischargeCurveGenerator.java:
	  Moved the method that adjusts the X-axis to include the "0" value from
	  ComputedDischargeCurveGenerator to DischargeCurveGenerator. Now, both
	  charts will include the "0" on the X-axis.

2011-06-23  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	  New. Base class for WQKms.

	  TODO 1: make it a base class for WQDay, too,
	  TODO 2: Generate instances of WQ instead of WQKms in "Abflusskurven"
	          calculations. This will save memory.

	  AT exporter will get instances of this class as data model

	* src/main/java/de/intevation/flys/artifacts/model/NamedObject.java:
	  Add default constructor to ease inheritance.

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java:

	  Removed superfluous imports.

2011-06-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	Improved situtation on rendering "Abflusskurve am Pegel". Not
	fully working, yet.

	* doc/conf/artifacts/winfo.xml: Generate facets for the location path, too.

	* src/main/java/de/intevation/flys/artifacts/model/FacetTypes.java: Misspelled
	  the facet which prevented the facets from being to the outputs.

	* src/main/java/de/intevation/flys/artifacts/model/WaterlevelFacet.java:
	  Extended to store the hash and the state id of the producing artifact/state
	  else it results in NPEs because the data is calculated on later (wrong) states.

	* src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java:
	  Store the state id and the hash in the facet, too.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Add two
	  method to do calculations for a state the artifact is currently not in
	  and fetching the current state id.

	  After a zoom action has taken place, this behaviour is no longer
	  supported.

2011-06-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	Draw correction curve again.

	* src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionGenerator.java:

	  the correction curve from being drawn!
	  Smaller code cleanups and simplifications.

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java,
	  src/main/java/de/intevation/flys/artifacts/model/WQCKms.java:

2011-06-18  Sascha L. Teichmann <sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/Calculation1.java:
	  Allow an explicit reference km to enable calculation "am Pegel".

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  If a calculation "am Pegel" is done, take start km of the
	  calculation range and find the gauge in which range it is located.
	  Take the station of the gauge as the reference km. If no gauge
	  is found the calcualtion falls back to calculation "auf freier Strecke".

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:

	* src/main/java/de/intevation/flys/collections/AttributeWriter.java,
	  src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Use
	  more 'standard' Java naming conventions.

	  the artifact.

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java: Added
	  methods computeAdvance() and computeFeed() called if artifact is fed or

	  src/main/java/de/intevation/flys/artifacts/states/DurationCurveState.java,
	  src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java: These
	  states overwrites the computeAdvance() and computeFeed() methods to do
	  the corresponding WINFO calculations.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Calls 
	  computeAdvance() and computeFeed() if artifact is fed or advanced. Centralized
	  the caching mechanism.

	  Uses facets to fetch data and generate output now.

2011-06-17  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Added a new parameter "wq_free" that
	  determines the mode of calculation 1. If it is "false" (default),
	  the calculation should be bound to a gauge.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added a
	  method to retrieve the information about the "wq_free" parameter.

	  represent percental values for the start and end point of x and y axes.
	  E.g. a chart has three axes with the following ranges:
	    - x axis  :  0 - 10
	    - y axis 1: 20 - 40
	    - y axis 2: 40 - 90

	Refactored version of "Berechnung 4"

	* src/main/java/de/intevation/flys/artifacts/model/Segment.java:
	  Added instance fields for a reference point (= location of gauge)
	  and backup of values (needed for naming).

	* src/main/java/de/intevation/flys/artifacts/model/WQCKms.java:
	  Added a constructor to be created from a WQKms. This is helpful
	  if a WQKms is replaced by a back jump correction.

	* src/main/java/de/intevation/flys/artifacts/model/Calculation4.java:
	  New. Outfactored version of "W bei ungleichmaessigen Abflusslaengsschnitt".
	  Much cleaner now and it should have a better handling of the corner
	  cases.

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Removed the linear interpolation stuff. It is now in Linear. Removed
	  the LinearRemap interpolation method because it is not needed any
	  longer. Added a method to interpolate a given km with a given
	  function.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Removed the old calc 4 and used the new one.

	* src/main/java/de/intevation/flys/artifacts/math/LinearRemap.java:

	  flys/issue90(Diagramm: Trennung der Diagrammfläche und Achsen aufheben)

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
	  Determine the ranges of x and y axes. If no zoom ranges are given, we
	  will determine the min and max xy values in the dataset manually,
	  because JFreeCharts adds a margin to the left and right of the data
	  area automatically..

2011-06-03  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Moved
	  the chart creation into an own public method. This lets the
	  ChartInfoGenerator create charts without duplicating code.

	* src/main/java/de/intevation/flys/exports/ChartInfoGenerator.java:
	  Limited the possible class for generators to XYChartGenerator. This
	  enables the ChartInfoGenerator class to do the whole chart creation
	  stuff itself without outsourcing the code to concrete subclasses.

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionInfoGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionInfoGenerator.java,

	  now.

2011-06-03  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/ChartGenerator.java: Added new
	  methods to extract the x and y ranges from request document.

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Added a
	  method that zooms the chart to the specified x and y ranges.

2011-06-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* doc/conf/conf.xml: Set collection ttl to 6 hours.

2011-06-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/Segment.java:
	  New. Parse segments only once.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Expose new parser to artifacts. TODO: Use it.

2011-06-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Changed interpolation methods to interpolate to an arbitrary position
	  in a given double result array as a preparation for segment independent
	  calculation.

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Removed superfluous import.

	* src/main/java/de/intevation/flys/artifacts/math/BackJumpCorrector.java:
	  Fixed cause for crashing: Run back too far in some siutations.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Refactored range code a bit. Needs more work.

2011-06-01  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/InfoGeneratorHelper.java:
	  Interchange the lower and upper x value of the chart if the x-axis is
	  inverted before the matrix values are computed. Now, the matrix is able
	  to work with charts that have an inverted x-axis.

2011-06-01  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/ChartInfoGenerator.java: New. A
	  chart info generator generates a document that contains meta information
	  for a specific chart. Concrete instances of this abstract class need to
	  instantiate concrete ChartGenerators and dispatch nearly all methods of
	  an OutGenerator (init(), doOut(), setMaster()) to this instance. The
	  generate() method is implemented in the ChartInfoGenerator itself. It
	  creates a chart with help of the ChartGenerator instance and builds a
	  document that contains meta information of this chart.

	* src/main/java/de/intevation/flys/exports/InfoGeneratorHelper.java: New.
	  This helper is used to create the chart info document. At the moment,
	  the only information that is included in this document is a
	  transformation matrix to transform image coordinates into chart
	  coordinates.

	  NOTE: The transformation matrix creation needs some work to support
	  charts with inverted X axis.

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionInfoGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionInfoGenerator.java,
	  src/main/java/de/intevation/flys/exports/DurationCurveInfoGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeCurveInfoGenerator.java,
	  src/main/java/de/intevation/flys/exports/ComputedDischargeCurveInfoGenerator.java:
	  Concrete instances of ChartInfoGenerator that create the chart info for
	  the currently supported chart types.

	* doc/conf/conf.xml: Registered new OutGenerators.

2011-05-31  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Added support for the 'type' paramter of the collection's out()
	  operation.

2011-05-31	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Use an explicit reference km for interpolation now.

2011-05-30	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* doc/conf/cache.xml: Introduced cache to store the distance info per river.
	  This boosts performance in following ab setup from  3.61 to 39.91 requests/secs.

	  $ ab -c 20 -n 1000 -p distances.xml http://127.0.0.1:8181/service/distanceinfo

	  $ cat distances.xml
	    <?xml version="1.0" encoding="UTF-8"?>
	    <art:river xmlns:art="http://www.intevation.de/2009/artifacts">Elbe</art:river>

	* src/main/java/de/intevation/flys/artifacts/model/AnnotationsFactory.java: Added
	  an iterator result to avoid construction expensive interim lists.

	* src/main/java/de/intevation/flys/artifacts/services/DistanceInfoService.java: Use
	  the cache if configured.

2011-05-30	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	flys/issue82

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:

2011-05-27	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/math/BackJumpCorrector.java:
	  Make it work independent of river flow direction.

	* src/main/java/de/intevation/flys/artifacts/states/WQAdapted.java:
	  Fixed bug in ordering segments

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Re-enabled
	  calculation of the back jump correction. Fixed more flow direction issues.
	  
2011-05-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Removed call of XMLDebug class which is not in the version control.

2011-05-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Moved the code part that skips themes right after the part that sets the
	  master artifact for the OutGenerator. We need this master artifact to
	  display empty charts - master artifact is used to create titles and
	  axes.

2011-05-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Deactivated themes are not put into the chart.

2011-05-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/AttributeParser.java:
	  Repaired broken XPath expressions to find the output modes in an
	  attribute document of a collection.

	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: This
	  writer will now create a document that has a root node art:attribute.
	  Before these changes, the document's root node was art:outputs which is
	  part of the attribute document but not the right root node.

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Adapted some XPath expressions and corrected the the process to create
	  attribute documents.

2011-05-26	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/math/LinearRemap.java:
	  Made it work independent of from/to order.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Added method to extract the ranges correctly from data.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:

	  Prevent NPE.

	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java:
	  Allow to be 'from' greater than 'to' in ranges.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Negate
	  step if 'from' is greater than 'to'.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Round exploded values to a precision of 1e-6.

2011-05-25	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

2011-05-24	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTableFactory.java:
	  Moved cache name to WstValueTableCacheKey. Do not cache null references.

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTableCacheKey.java:
	  Moved cache name into this class.

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Store QRangeTree for each column of value table. TODO: Use them!

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTableFactory2.java:
	  Intended as a replacement for WstValueTableFactory, but is work in progress.

	* src/main/java/de/intevation/flys/artifacts/model/QRangeTree.java: Fixed
	  index errors and added methods to dump as graphviz graph.

2011-05-24  Ingo Weinzierl <ingo@intevation.de>

	  the DischargeCurveGenerator which should do the same stuff for discharge
	  curves for gauges.

	* src/main/java/de/intevation/flys/exports/ComputedDischargeCurveExporter.java:
	  New. This is only a stub implementation at the moment. This OutGenerator

	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Added new i18n strings for
	  for the location selection.

2011-05-03  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/DurationCurveGenerator.java:
	  New. An OutGenerator for creating duration curves.

	* src/main/java/de/intevation/flys/artifacts/model/WQDay.java: New. A
	  model class to store necessary data for creating W and Q facets of a
	  duration curve. This model stores W, Q and Days.

	* src/main/java/de/intevation/flys/artifacts/model/MainValuesFactory.java:
	  Added a function to retrieve tuples of (day, q) based on a given gauge -
	  these tuples are necessary for creating duration curves.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Added
	  methods to compute and retrieve the data necessary for creating duration
	  curves.

	* src/main/java/de/intevation/flys/artifacts/states/LocationSelect.java:
	  Bugfix: improved the access to the location array (avoid
	  NullPointerException).

	* doc/conf/conf.xml: Registered the new OutGenerator for duration curves.

2011-05-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* contrib/visualize-transitions.xsl: State quoting was done wrong.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Enhanced the transition model to reach the
	  final state for creating duration curves.

	* src/main/java/de/intevation/flys/artifacts/states/LocationSelect.java:
	  New. This state should be reached to just insert an array of locations.

	* src/main/java/de/intevation/flys/artifacts/states/DurationCurveState.java:
	  New. This state is reached if the duration curve calculation is
	  selected.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Adjusted
	  getDistance() so that it takes care on inserted locations - not just
	  inserted ranges.

2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/cache/CacheFactory.java:
	  Flush/persist caches at program exists.

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  Commented out too eloquent debug output.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Uses the methods of FLYSArtifact to retrieve the necessary information
	  rivername and selected distance.

2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Added interpolateW method to take reference to result ws array
	  as an argument to avoid expensive array allocations in km iterating
	  loops.

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java:
	  Added a constructor to create backing trove datastructure
	  with the right capacity.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Move allocation of result ws out of km loop.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Added two further data items in the WQ
	  selection state. Those items are necessary to store the information
	  about the selected mode (range/single selection) and  the values of the
	  single selection.

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java: If
	  there is no value for a data item, this item is not written into the
	  static DESCRIBE part.

	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java,
	  src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java:
	  Renamed the method to validate upper and lower values.

	* src/main/java/de/intevation/flys/artifacts/states/WQSelect.java: This
	  state can now handle values inserted in the single selection. Therefore,
	  new validate methods has been added.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: The
	  methods getWs() and getWs() take care on the values inserted in the
	  single insert mode of the client which enables the user to insert single
	  W and Q.

2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Repaired getQForW() by calculating indices on right dimension.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: New
	  methods for retrieving selected W values (getWs()).

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  method for retrieving waterlevel data takes care on selected Ws, now.
	  The selected Ws are transformed using the DischargeTables.getQForW()
	  into Q values.

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Removed an unused parameter 'result' of getQForW().

2011-05-02  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Removed
	  the getDataset() method and replaced it with a addDataset() method.
	  On this way, concrete subclasses of this OutGenerator can have multiple
	  datasets (e.g. different datasets for W and Q). This abstract method is
	  called after the chart generation is finished.

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Both classes implement the addDataset() method. The
	  LongitudinalSectionGenerator has already multiple datasets for W and Q.
	  Both are added to the chart - both have an own range axis.

2011-05-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Use the cache for the wst value table if configured.

	* doc/conf/cache.xml: Choose a more precise name for the 
	  wst value table cache.

2011-04-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* pom.xml: Added dependency to Ehcache. Apache 2.0 license.

	* doc/conf/conf.xml: Added configuration of ehcache.

	* doc/conf/cache.xml: New. Cache configurations.

	* src/main/java/de/intevation/flys/artifacts/cache/CacheFactory.java:
	  New. Factory to access caches.

2011-04-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Forgot to add.

	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
	  New. Given a database connection and a XML template it generates
	  an output with meta data about the database.

	* src/main/java/de/intevation/flys/artifacts/services/meta/CompiledStatement.java:
	  New. Holds prepared statements optimized to be run in the stack of
	  contextes.

	* src/main/java/de/intevation/flys/artifacts/services/meta/StackFrames.java:
	  New. Model to hold a hierarchical scope of variables.

	* src/main/java/de/intevation/flys/artifacts/services/meta/ResultData.java:
	  New. Stores data set fetched from a sql select to be iterated in
	  a context.

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java,
	  src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Removed superfluous imports.

2011-04-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* doc/conf/conf.xml: Added meta data service.

	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
	  Stub for the meta data service.

	* src/main/resources/metadata/template.xml: Initial template for
	  the meta data service.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Bugfix: Now, curves for Q values are drawn into a longitudinal section
	  chart as well. Therefore, it was necessary to change the datastructure
	  of the inner class ThemeList that stores all themes included in a chart
	  in an ordered list (stored in a java.util.Vector now).

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: New. An
	  abstract base class for ChartGenerators that create XY charts.

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Sourced the generate() method out to the XYChartGenerator.

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  Implemented the methods to add W and Q facets to the chart.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Improved
	  the calculation of the step with for ranges.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java: Added a
	  method that returns the number of elements stored in the data pool.

2011-04-29	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java:
	  Added a get() method which takes destination array as an
	  argument.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java: Changed the
	  data structure to store w, q and kms values from List<Double> to
	  TDoubleArrayList which stores native double values instead of big
	  Double values.

	* pom.xml: Added the GNU Trove dependency.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/OutGenerator.java: Added the
	  name a the requested facet to doOut(). Concrete generators should just
	  create output for this facet now.

	* src/main/java/de/intevation/flys/exports/ChartGenerator.java,
	  src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java,
	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  Adapted the method signature of doOut().

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Adapted the method call of OutGenerator.doOut().

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/themes.xml: Added mappings for the facets
	  longitudinal.section.w and longitudinal.section.q.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added some
	  methods to retrieve necessary information for computing the data of a
	  waterlevel.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Added
	  methods to compute and retrieve the data of a waterlevel computation.

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java: New. This
	  model class represents a pool of data triples that consist of W, Q and
	  Kms information. This class might be used to compute data for creating
	  longitudinal section curves (which are based on those W, Q and Kms
	  values).

2011-04-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Bugfix: Removed endless loop and a bug while iterating over Hibernate
	  results.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
	  New. An OutGenerator that creates longitudinal section curves.

	  NOTE: This is just the stub - the out creation needs to be implemented!

	* doc/conf/conf.xml: Added the LongitudinalSectionGenerator.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: Bugfix: Added missing <output-generators> section.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WaterlevelState.java: New.
	  This state should be reached if the 'calc.surface.curve' calculation
	  method has been chosen.

	* doc/conf/artifacts/winfo.xml: Modified a transition and added the
	  WaterlevelState. This state is reached if the 'calc.surface.curve'
	  calculation method has been chosen. It currently has 1 output - a
	  longitudinal section that is not implemented yet!

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/transitions/ValueCompareTransition.java:
	  New. This transition is valid if the a data object of the current
	  artifact equals/notequals a configured value in the transition model.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Bugfixes:
	  - Adapted the parameters of the isStateReachable() call - added the
	    artifact and the current state.
	  - Append the outputs of a current state if the state is filled with
	    valid data.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/transitions/DefaultTransition.java:
	  Added the missing init() method that has been introduced in the
	  interface some commits ealier.

	* src/main/java/de/intevation/flys/artifacts/transitions/TransitionFactory.java:
	  Call init() after a Transition has been created.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/AttributeWriter.java:
	  Bugfix: Introduced a <art:outputs> node in the attribute document of a
	  Collection that contains further <art:output> nodes - instead of having
	  multiple <art:output> nodes at toplevel of the document.

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Adapted the XPath to retrieve the outputs in the attribute document of a
	  Collection.

2011-04-28	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* contrib/visualize-transitions.xsl: Added to create a 
	  Graphviz digraph out of the config.xml. Usage:

	  $ xsltproc --stringparam base-dir ../doc/conf/ \
	    contrib/visualize-transitions.xsl \
	    doc/conf/conf.xml > transitions.dot

	  $ dot -Tsvg -o transitions.svg transitions.dot

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/WQSelect.java:
	  If no data has been inserted so far, an IllegalArgumentException is
	  thrown.

2011-04-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java::
	  A lot of new methods to retrieve the theme of a facet - used while
	  creating the output of a facet/artifact. If a facet has no theme yet, it
	  is initialized.

2011-04-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/AttributeParser.java,
	  src/main/java/de/intevation/flys/collections/OutputParser.java: Removed
	  useless imports.

2011-04-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/ChartGenerator.java: New. An
	  abstract OutGenerator that might be used to create chart output. Some
	  basic things that are equal in all charts should be done here!

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  This OutGenerator no longer implements the OutGenerator directly, but it
	  extends the ChartGenerator now.

2011-04-27  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Restructured the out() operation of a collection: Now, we collect a list
	  of artifacts/facets and use this for the OutGenerator. Its doOut()
	  method gets the attribute of an artifact - the position and the active
	  state is managed by the Collection itself.

2011-04-26  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacet.java: New.
	  a specialized facet that stores information about its position and its
	  state (active/inactive) in an output of a collection.

	* src/main/java/de/intevation/flys/collections/AttributeParser.java: New.
	  This parser takes the attributes (XML) of a collection and extracts the
	  contained outputs with its facets. The result is a Map<String, Output>.

	* src/main/java/de/intevation/flys/collections/OutputParser.java: New.
	  This parser is used to query the artifact's DESCRIBE and to extract the
	  supported outputs. The result is a Map<String, Output>.

	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: New.
	  This writer merges the outputs contained in an attribute of a collection
	  with the outputs of a collection's artifacts.

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  The attributes of a collection are written into its DESCRIBE document
	  now. The OutputParser and AttributeParser are used to read the supported
	  attributes by the collection and its artifacts - the AttributeWriter is
	  used to merge both attributes and create a final attribute document.

2011-04-26  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java,
	  src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  The facet-2-theme mappings are initialized at startup and stored in the
	  FLYSContext.

	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: Added a
	  function that retrieves a theme from FLYSContext based on its name.

2011-04-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Corrected a silly c&p mistake.

2011-04-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/math/BackJumpCorrector.java:

	  Implementation of the "Ruecksprungkorrektur" to be done in
	  "W fuer angepassten Abflusslaengschnitt".

	  All tests show the expected results. In some corner cases the
	  algorithm described in the "Anwenderhandbuch" chapter 3.3.4.3 "Korrektur"
	  has some definition shortcomings:

	  a - What should happend when you cannot find point 2 because
	      you cannot step back one quarter from point 3 because there
	      is no data there any more (river too short in this direction)?
	      The implemented algorithm raises point 3' only to an
	      according factor. E.g. If you can step back the whole quarter
	      distance the elevation is the full quarter. If you can
	      step back only the half of the quarter the elevation is
	      only an eighth.

	  b - If the water heights between point 2 and 3 are constant then
	      the algorithm will produce a spline interpolation that
	      lowers those values. Is this intended?

	  For real data the back jumps are expected to be more in the middle
	  of the distance ranges so the corner cases are maybe not so
	  important.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Removed superfluous import.

2011-04-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: Removed debug
	  code that has been commited by accident.

2011-04-21  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/themes.xml: New. A first small theme configuration.

	* doc/conf/conf.xml: Added a link to the theme configuration.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java:
	  Defined a key that is used to store a themes map in the FLYSContext.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  The theme configuration is read at startup and the themes are stores in
	  the FLYSContext.

2011-04-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/themes/Theme.java,
	  src/main/java/de/intevation/flys/themes/DefaultTheme.java:
	  New. The interface and its default implementation that represents themes
	  used to style charts and maps.

	* src/main/java/de/intevation/flys/themes/ThemeField.java,
	  src/main/java/de/intevation/flys/themes/DefaultThemeField.java:
	  New. The interface and its default implementation that represents fields
	  in themes. A theme might be "Lines" and one of its field might be
	  "Color" or "Size".

	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: A factory
	  that creates new themes based on a theme configuration.

2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  Implementation of "Abflusskurve/Abflusstafel" calculation.

	  Added method interpolateWQ() which takes an km and results in a
	  tuple of two double arrays containing the w/q values interpolated
	  between the surrounding w/q values of the table.
	  w values are interpolated linear, q values with a cubic spline.

	  Drawing w over q gives you the discharge table at the given km.

	  !!! This code needs testing !!!

2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* pom.xml: Added dependency to Apache Commons Math 2.2 (Apache License 2.0)

2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Fix problem when sorting by q (copied w instead of q).

2011-04-20  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Fixed broken HQL statement.

2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
	  add a method interpolateW() which takes an array of
	  q values and returns an equal sized array of w values.
	  This is essentially the "Wasserstand/Wasserspiegellagen" calculation
	  of desktop FLYS.

	  If you want to do a calculation with given w values you have
	  to convert the w values with DischargeTables.getQForW() first.

	  !!! This code needs heavy testing !!!

2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  We need a getQForW() method and not getWForQ() because when
	  doing a "Wasserstand/Wasserspiegellagen" calculation with given
	  w values these values need to be translated to q values with
	  the master discharge table.

2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Sorting of q values was done wrong.

2011-04-19  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/AnnotationsFactory.java:
	  Ordered the list of annotations returned by this factory based on its
	  range.

2011-04-19  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/MainValuesService.java:
	  New. This service returns an XML document that includes the main values
	  of a gauge based on a river name, a start and an end point.

	* doc/conf/conf.xml: Registered the MainValuesService.

2011-04-19  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/MainValuesFactory.java:
	  A factory that provides methods to return MainValues.

	  should raise an exception.

	  NOTE: The exceptions are not translated in the server but in the client!

	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java: New.
	  This abstract class exists to provide some methods for handling ranges.
	  Currently, there is a method that validates a given range based on
	  min/max values.

	* src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/WQSelect.java:

	  artifacts in the UI.

2011-04-12  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Bugfix:
	  States are filled with data before they describe themself.

2011-04-11  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/AnnotationsFactory.java:

	  the code to create discharge curves. It has moved to the
	  DischargeCurveGenerator which now does this work.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Changed
	  the visibility of the getData() method. It's now public, because the
	  OutGenerator needs an artifact's data.

2011-04-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/**/*.java: Removed trailing whitespace.

2011-04-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	  different arguments will result in the same output.

2011-03-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Introduced a 'scale' parameter in the getValues() method.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Filled
	  the out() operation with code that draws a discharge table of one or
	  more gauges specified by the given range in entered in a previous state.

	* doc/conf/conf.xml: Use the FLYSArtifactCollection instead of the
	  DefaultArtifactCollection for this application.

2011-03-24	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	  Removed needless import.

2011-03-24  Ingo Weinzierl <ingo@intevation.de>

	* src/main/resources/messages_de_DE.properties: Added a german resource
	  bundle to avoid exceptions in the flys artifacts. Sometimes, the
	  Resources class is not able to find a 'de_DE' bundle and throws an
	  exception. This is really strange, because it should use the 'de' bundle
	  in that case, but it doesn't.

2011-03-23  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Added
	  some code to append the output modes of previous states to the DESCRIBE

	  New. A state for the location/distance selection of the WINFO
	  parameterization.

2011-03-17  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added a new method getUIProvider() that might be overriden by concreted
	  subclasses that should be rendered with a specific UIProvider.

2011-03-17  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  The static UI part is created by the previous states now. This makes it
	  possible to group the data objects (which is necessary to group the
	  objects in the ui).

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added a describeStatic() method that creates a node that contains the
	  data of that state.

	* doc/conf/artifacts/winfo.xml: Modified the winfo states.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Adapted
	  the artifact regarding the changes of the last commit. The states

	* src/main/java/de/intevation/flys/artifacts/states/CalculationSelect.java:
	  New. The state for choosing the calculation mode.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Added i18n strings for the
	  calculation mode state.

2011-03-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  New. This is the base state for the FLYS application. It provides a
	  method that creates the dynamic ui node for the DESCRIBE.

	  the data that have been inserted in former states into the static node
	  of the DESCRIBE.

2011-03-10  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: The
	  operations feed() and advance() return the description of the artifact
	  using the describe() operation. This avoids additional server round trips
	  in the client - the clients gets to know about the new state of the
	  artifact immediately.

2011-03-10  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Implemented a part (step forward) of the advance operation.

	* TODO: Implement Step-Back in advance operation.

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Implemented the abstract method getName(). It returns the constant
	  'winfo' string.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Implemented the feed action. The data of an incoming feed() operation is
	  stored in StateData objects that are saved in a map in the artifact.

	  NOTE: There is no input validation and no i18n of error messages (see
	  TODO).

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* TODO: This file contains some open points that need to be done.

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: New. This
	  artifact serves as the default artifact for the FLYS application.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: This
	  artifact now inherits from FLYSArtifact. Furthermore, there is one big
	  change: we don't store the State objects itself in the artifact, but
	  just the identifier of those. This makes the artifact smaller and more
	  compatible agains previous versions of the software.

2011-03-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/RiverService.java:
	  New. This service will retrieve a list of provided rivers.

	* doc/conf/conf.xml: Added a configuration for the RiverService.

2011-03-07  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: Added a section user-factory and collection-factory in
	  the factories part of the configuration.

2011-03-01  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Replaced the 'special' attribute from DESCRIBE with a 'uiprovider'
	  attribute.

2011-02-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  RiverSelect state is called to create the UI part of the describe
	  document.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Implemented the dynamic UI part of describe(). The static part is not
	  inserted into the describe document at the moment. We need a reference to
	  the previous states for this.

2011-02-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/RiverFactory.java,
	  src/main/java/de/intevation/flys/artifacts/model/River.java: New. A model
	  class that represents a river and its factory to create concrete river
	  instances.
	  NOTE: Currently, this is just a mockup. The factory just returns two
	  static rivers "Mosel" and "Saar" without a connection to a backend.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/StateFactory.java: The
	  input data of a state is initialized with empty StateData objects after
	  the State has been created.

	* doc/conf/artifacts/winfo.xml: Renamed the input data nodes of the states
	  which now fits better to the class name of the implementation.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  describe document returned by this artifact now contains the current state
	  and the reachable states.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  The transitions are put into the TransitionEngine with the ID of the state
	  - not longer with the artifact name. On this way, we are able to fetch
	  just the transitions for a specific state, instead of all the transitions
	  of an artifact.

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Describe()
	  returns the artifact's uuid and hash value. The whole implementation of
	  describe() is still outstanding.

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Removed useless config stuff.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Removed
	  useless methods, and improved the init process - the first state is set as
	  the current state for this artifact.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/GaugeSelect.java: New.
	  The states are used in the first two steps of the WINFOArtifact.
	  Currently, they just implement stubs of the necessary methods setup() and
	  describe().

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/State.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/TransitionEngine.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/Transition.java:
	  Removed. These classes are placed in the artifact-database now.

	* src/main/java/de/intevation/flys/artifacts/transitions/DefaultTransition.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/TransitionFactory.java:
	  Adapted imports of Transition.

	* src/main/java/de/intevation/flys/artifacts/states/StateFactory.java: New.
	  This factory should be used to create concrete State objects.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java: Added
	  a constant key to store the StateEngine in the context.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  New method that initializes the states at application start.

2011-02-03  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/State.java: New. The
	  interface description of a state.

	* src/main/java/de/intevation/flys/artifacts/transitions/Transition.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/DefaultTransition.java:
	  New. The interface description and a default implementation of a
	  transition.

	* src/main/java/de/intevation/flys/artifacts/transitions/TransitionEngine.java:
	  New. The TransitionEngine stores all transitions for each artifact and
	  should be used to determine, if an artifact can advance from one state to
	  another.

	* src/main/java/de/intevation/flys/artifacts/transitions/TransitionFactory.java:
	  New. Transitions should be created by using this class.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java: New.
	  The Flys context. It currently defines keys to store important components
	  in the context.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  New. The context factory initializes the basic components of the
	  application. Currently, the TransitionEngine is created and all artifacts
	  with its transitions are read from the global configuration and stored in
	  the FLYSContext.

	* pom.xml: Added a dependency to the 'artifacts-common' package.

	* doc/conf/artifacts/winfo.xml: Corrected the classname of the
	  DefaultTransition.

	* doc/conf/conf.xml: Added FLYSContextFactory as context-factory.

2011-02-02  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: An initial configuration file for the FLYS artifact
	  server.

	* doc/conf/artifacts/winfo.xml: An initial transition configuration of an
	  WINFO artifact.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: A stub of
	  an artifact for a WINFO parameterization.

	* pom.xml: Set the source code version to 1.5.

2011-02-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/**, pom.xml: Added initial maven project.
	* ChangeLog: new.
