	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Artifacts and Collections that started a background process might add
	  Messages to a message board now. They (currently just implemented for
	  the Artifact) can add new messages and receive a list of messages via
	  the CallContext objects. If an Artifact or Collection instance is
	  removed from background, all its messages are removed as well.

	* artifacts/src/main/java/de/intevation/artifacts/Message.java: New. The
	  message interface. Currently, there is just a single getText() method
	  defined.

	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java: Got
	  two new methods to add new messages and retrieve a list of messages to
	  the background messages.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/CollectionCallContext.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactCallContext.java:

	  !! NOTE: This modification breaks the current API !!

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactFactory.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactFactory.java:
	  Call Artifact.setup() with an instance of CallMeta.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  The createArtifact() method got a CallMeta instance which is necessary
	  to call Artifact.setup().

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Facet.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultFacet.java:
	  A facet can write its internal representation to XML using a public
	  method toXML(Document).

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProtocolUtils.java:
	  Facets are appended using its toXML() method. Concrete facets can now
	  change its xml representation.

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

	* artifacts/src/main/java/de/intevation/artifacts/Hook.java: The Hook's
	  execute() method is called with a Document now.

	  documents which are returned by those operations.

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

	* artifacts/src/main/java/de/intevation/artifacts/GlobalContext.java: New.
	  An interface for global context objects. It defines two basic operations
	  to put objects into the context and to retrieve objects from context.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
	  Added a method that returns an instance of an Artifact with one
	  limitation: the internal state of this artifact is not persisted to
	  database!

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  Added a method that creates a document used to create new Artifacts with
	  the UUID of another one.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java,

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Output.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultOutput.java:
	  An Output can have a type (string) declaration now that should make it
	  easier to distinguish different Output types.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/AbstractState.java:
	  Read the attribute "type" from OutputMode's configuration section.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProtocolUtils.java:

	  flys/issue50 (Markierung von "Master-Artefakten" ermöglichen)

	* artifact-database/doc/schema-pg.sql,
	  artifact-database/doc/schema-h2.sql: Added a column 'creation' to the
	  collection_items table. This column is set to the current timestamp when a
	  new row is inserted in this table. The master artifact of a collection
	  is the artifact which collection item is the oldest collection item in
	  the collection.
	  Note: there might be older artifacts in the collection than the master
	  artifact, but there will never be an older collection item than the first
	  item when the collection was created.

	  To update the db, use the following statements:

	    ALTER TABLE collection_items ADD COLUMN creation TIMESTAMP;
	    UPDATE collection_items SET creation = CURRENT_TIMESTAMP;
	    ALTER TABLE collection_items ALTER COLUMN creation SET NOT NULL;

	  artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
	  Added a setCollectionTTL() method that might be used to update the TTL
	  of a collection. The new value needs to be from type long. There are two
	  exceptions for the new values:
	    1. the new value is "INF": this lets collections live forever.
	    2. the new value is "DEFAULT": this sets the TTL of the collection to
	       the configured default value.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Added a method to update the TTL attribute of a collection.

	* README: Adjusted to use new lib versions.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  The incoming attribute document of the method to create the document to
	  trigger the out() of a collection needs to have the root node
	  art:attribute now.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/BaseOutResource.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionOutResource.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactOutResource.java:
	  The 'type' part of the url is extracted and used while dispatching the
	  call to the artifact database.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java,
	  artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:

	  artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java,
	  artifacts/src/main/java/de/intevation/artifacts/ArtifactCollection.java,
	  artifacts/src/main/java/de/intevation/artifacts/Artifact.java:
	  Artifacts and ArtifactCollections have two out() operations to support
	  the output type parameter now. I did not remove the out() without the
	  'type' parameter to keep compatible with older versions.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  The setCollectionAttribute() method will now set the incoming document
	  as new attribute for the collection. Before, we looked for a xpath
	  expression that contained the attribute. In the current implementation,
	  the incoming document IS the attribute.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionResource.java:
	  Extract the new attribute for a collection and call the
	  setCollectionAttribute() method of ArtifactDatabase with this document
	  instead of calling it with the incoming request document.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:

	  New. Use embedded Jetty server to serve rest API.
	  To enable it set "/artifact-database/rest-server/http-server/text()"
	  in global config to "de.intevation.artifactdatabase.rest.JettyServer".

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/Standalone.java:
	  Refactored a bit to be useful as a base class.
	
2011-04-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	  HTTP servers.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/Standalone.java:
	  Implements the new interface.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java:
	  Load and setup the HTTP server configured by the XPath 
	  "/artifact-database/rest-server/http-server/text()" in the global config file.
	  Defaults to "de.intevation.artifactdatabase.rest.Standalone" if not given.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: 
	  Boot with the HTTP server configured by FactoryBootstrap.

2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/Standalone.java:
	  With '/artifact-database/rest-server/max-threads/text()' in conf.xml
	  you can set the number of threads used by the restlet server.
	  Defaults to 1024 now. Another attempt/workaround to cope with flys/issue65.

2011-05-17  Ingo Weinzierl <ingo@intevation.de>

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  Bugfix: The output name and its concrete type are both written into the
	  document that is used to trigger the OUT operation of a collection.

2011-04-17	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/pom.xml: Bumped restlet to version 2.0.7 in hope

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/transition/Transition.java:
	  Modified the isValid() method. The transition needs to know about the
	  current artifact where its data is stored, the current state and maybe
	  the target state to determine if it is allowed to step from the current
	  state to a target state!
	  NOTE: This breaks the current API!

	  call ArtifactDatabaseImpl.initCallContext() in constructor and 
	  ArtifactDatabaseImpl.closeCallContext() in postCall().

	* artifact-database/src/main/java/de/intevation/artifactdatabase/CollectionCallContext.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactCallContext.java:

2011-04-06	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Fix for flys/issue8 (part 2)

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	  PostgreSQL does not like clauses like 'NOT IN ()' so write 
	  'NOT IN (NULL)' in these cases.

2011-04-06	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Possible fix for flys/issue8

	* artifact-database/src/main/java/de/intevation/artifactdatabase/StringUtils.java:
	  (repeat) The term was repeated one time too often leading to invalid
	  SQL statements in database cleaner. I really should start writing 
	  unit tests.

2011-04-06  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultCollectionItem.java:
	  Bugfix: Items are compressed in the Backend while adding an Artifact to
	  a Collection. So this item needs to be decompressed when it is fetched
	  from Backend again. This is done now!

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  The XML documents stored aside users, collections and collection items
	  are now compressed/decompressed transparently, to reduce i/o costs
	  as its already done with artifacts.
	  
	  !!! This breaks database content of release FLYS 2.2 but this is okay,
	  !!! because 2.2 is not productive..

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/XMLUtils.java:
	  Added a boolean flag to XML byte serialisation to compress/decompress, too.
	  Defaults to false to keep compatibilty.

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

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

2011-03-31	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	  Removes outdated collections, too.

	* src/main/resources/sql/org-h2-driver.properties,
	  src/main/resources/sql/org-postgresql-driver.properties:
	  Added SQL statements to figure out outdated collections.

2011-03-31	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/StringUtils.java:
	  Added methods to repeat chars or strings.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	  Filtering out locked artifact ids is now done on database level.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Added $LOCKED_ID$ template for the prepared statements to figure
	  out the locked ids.

2011-03-31	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	  The cleaner now fetches the explicit set of locked artifact ids from
	  the artifact database. This is needed for the next step todo: Prevent
	  locked artifact from beeing considered as outdated on database level.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Id.java:
	  Removed. Not needed any more.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Now provides a copy of the locked artifact ids.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Adjusted code to follow the new id locking semantics.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultOutput.java:
	  Removed needless import.

2011-03-31	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/doc/schema-h2.sql, artifact-database/doc/schema-pg.sql:
	  Added a trigger on artifacts. If an artifact is changed the last_access
	  timestamp of the collections in which the artifact is in are updated, too.
	  Needs testing!

	  - In PostgreSQL it is done by a trigger written in plpgsql. So don't
	    forget to add the language to the database!

	  - In H2 it is done by a trigger written in Java, because H2 does not
	    offer a script level trigger support.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/h2/CollectionAccessUpdateTrigger.java:
	  The H2 trigger.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
	  Added the statement which is executed if the trigger fires.

2011-03-31  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Added an implementation of DeferredOutput for ArtifactCollections and
	  implemented the out() operation of an ArtifactCollection.

2011-03-30  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProtocolUtils.java:
	  The output nodes written to DESCRIBE document have facet nodes now.

2011-03-30  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultFacet.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/state/Facet.java:
	  New. A facet and its default implementation. A facet represents one
	  piece of an concrete output. E.g. an output can be a chart, a facet can
	  be a single curve in this chart.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultOutput.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/state/Output.java:
	  Added methods to retrieve and set facets.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/AbstractState.java:
	  Added code to parse facets in the inner of an output node of the
	  transition configuration. The xpath to a facet relative to a state
	  should look like this: state/outputmodes/outputmode/facets/facet.

2011-03-30  Ingo Weinzierl <ingo@intevation.de>

	Tagged as RELEASE 1.1

2011-03-30  Ingo Weinzierl <ingo@intevation.de>

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  There is a new method that creates the document that is used to trigger
	  the DESCRIBE operation of a collection.

2011-03-25  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  The operation that adds an artifact to an artifact collection will
	  return the DESCRIBE document of the artifact collection now.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactCollection.java,
	  artifacts/src/main/java/de/intevation/artifacts/ArtifactCollection.java:
	  Made the document 'attribute' of the ArtifactCollection accessible via
	  getter and setter methods.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  The CREATE document for used for creating new ArtifactCollections will
	  build an ArtifactCollection with an empty attribute - but it is no
	  longer null (which broke the XML parser while fetching the
	  ArtifactCollection from backend).

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Removed the inner CallContextImpl class. This class is split up into an
	  abstract class AbstractCallContext and concrete classes for artifacts
	  and collections. We need to do so, because the describe() of an
	  ArtifactCollection needs the CallContext - but the former
	  CallContextImpl was specific for artifacts.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/AbstractCallContext.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/CollectionCallContext.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactCallContext.java:
	  An abstract CallContext and two concrete implementations for Artifacts
	  and ArtifactCollections.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactCollection.java,
	  artifacts/src/main/java/de/intevation/artifacts/ArtifactCollection.java:
	  There is a describe() method for ArtifactCollections, now.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Added a method that retrieves an ArtifactCollection based on its GID.

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

	* artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Added a cast to uuid in collections.select.by.gid

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

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Added new statement to retrieve a single collection by GID and repaired
	  a statement in the postgres properties.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  Added a method that creates a document that is used to add an artifact
	  to a collection.

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

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Bugfix: Repaired broken SQL statement.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  Bugfix: Repaired a broken XPath.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProtocolUtils.java:
	  Added a method to append an <outputmodes> section to a document that
	  describes the output modes of a state.

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  Added a method to retrieve a list of output modes from DESCRIBE
	  document.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/State.java:
	  The State interface defines a method to retrieve the state's output
	  modes now.

2011-03-22  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultOutput.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/state/Output.java:
	  New. An interface and its default implementation to describe an output
	  mode of a state. Currently, the information 'name', 'description' and
	  'mime-type' are provided.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/AbstractState.java:
	  The abstract state reads the output modes available for the state now.

2011-03-21  Ingo Weinzierl <ingo@intevation.de>

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  Changed the return type of a method, so that more nodes will be
	  retrieved.

2011-03-15	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	!!! THIS BREAKS THE GNV ARTIFACTS. !!! TODO: Adjust the imports there.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/XMLUtils.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java:
	  Deleted. The copies from the commons package are use now.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/**/*.java:
	  Adjusted imports.

2011-03-15	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/Config.java:
	  New. Copy of Config in artifacts-database. Part of moving configuration to 
	  the commons package. TODO: Remove XMLUtils and Config from artifact-database.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Trivial fix. Forgot to commit some time ago.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/State.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/state/AbstractState.java:
	  The describe() method of a state will now return an Element.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  New method that creates the document for a ADVANCE operation.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
	  New method that creates the document for a FEED operation.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/XMLUtils.java:
	  Bugfix: The ElementCreator's method addAttr() will no longer add the
	  namespace to an attribute although the 'addPrefix' parameter was set to
	  false.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/transition/TransitionEngine.java:
	  New method to determine if a state B is reachable from a state A.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/data/DefaultStateData.java:
	  Added a further constructor that takes even the value.

2011-03-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/doc/schema-pg.sql, artifact-database/doc/schema-h2.sql: 
	  Fixed broken schemas.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Insert collection attribute into database, too.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Adjusted SQL statements to insert attribute into collection table.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Parse the collection attribute that is contained in the incoming
	  document while creating a new collection and use this document as parameter
	  for calling createCollection() of the Backend.

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

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Fixed a typo.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java,
	  artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
	  New method describeCollection() that might be used to retrieve a list of
	  items in the collection and the facets supported by those items.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionResource.java:
	  Enabled the describeCollection() method with an action 'describe' equal
	  to the implementation of describe of an artifact.

2011-03-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/resources/sql/org-h2-driver.properties
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  The cleaner job is scanning the artifact database for outdated artifacts.
	  artifacts are aging independent from the collections they are in.
	  So the cleaner wants to delete artifacts that are still in
	  collections which violates a foreign key constraint and renders
	  the cleaner inop because this condition remains.

	  The fix prevents this behavior by only deleting artifacts that
	  are not in a collection.

2011-03-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Fixed issue with outdating artifact if it is removed from a collection.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Fixed statements.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:

	  Implemented removeCollectionArtifact() method.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java,
	  artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
	  Modified the method signature of addCollectionArtifact(). This method
	  got the incoming document as further parameter.
	  Furthermore, listCollectionArtifacts() and addCollectionArtifact() are
	  implemented now.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionResource.java:
	  Adapted the method call of addCollectionArtifact().

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultCollectionItem.java:
	  Fixed broken constructor.

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

	* artifact-database/doc/schema-pg.sql,
	  artifact-database/doc/schema-h2.sql: Renamed a SEQUENCE - schema
	  definition and sql statements did not fit to each other.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Fixed wrong table names in sql statements.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Fixed SQL constants.

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

	* artifacts/src/main/java/de/intevation/artifacts/CollectionItem.java:
	  New. An interface that wraps artifacts and its attributes in collections.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultCollectionItem.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/CollectionItem.java:
	  Moved. The CollectionItem has been moved to DefaultCollectionItem and
	  implements the new interface CollectionItem.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  The listCollectionArtifacts() method instantiates DefaultCollectionItem
	  objects now.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/CollectionItem.java:

	  via a given collection uuid.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Repaired the namespaces of attributes in the xml documents created in
	  the collection context.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/CollectionItem.java:
	  New. Helper to be returned in Backend.listCollectionArtifacts()

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Copyright adjusted to 2010, 2011

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

	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
	  Adapted the sql statement to fetch all collections and all user
	  collections from database (see rev1399 for more details).
	  s/OUTER LEFT/LEFT OUTER/ solves the collection listing problem.

2011-03-06	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:

	  given the collection and the artifact uuid.

2011-03-06	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Added new method isValidIdentifier() to check if identifier
	  is valid. Its a wrapper around StringUtils.checkUUID() to
	  make it more symmetric to newIdentifier() which wraps
	  StringUtils.newUUID().

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Added code to delete a collection.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
	  Added SQL statements to delete collections.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/SQLExecutor.java:
	  New. Helper class to simplify the database connection stuff like
	  get a connection, prepare statements, commit, rollback in
	  error cases and so on. This reduces the code repetition
	  and complexity in the backend significantly.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Use the new helper. (Should really have done this before!)

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactCollectionFactory.java:
	  Removed empty line at end of file.

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

	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:

2011-03-04  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  If there is no creation time of a collection, we just add an empty

	  object any longer but just its identifier.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Performance improvement: there is no need to fetch the user that we want
	  to delete from database before deleting it. Now, we just call the
	  deleteUser() method of the UserFactory with the identifier of the user.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/AbstractState.java:
	  New. An abstract implementation of a State. Some basic getter and setter
	  methods are implemented - setup() and describe() need to be implemented by
	  concrete subclasses.

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

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/StateEngine.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/transition/TransitionEngine.java:
	  Implementations to store the provided states and transitions of the
	  artifact server. These engines should be filled at bootstrap.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/State.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/transition/Transition.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/data/StateData.java:
	  Interface descriptions for states, transitions and user inserted data.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/XMLUtils.java:
	  Corrected the package definition.

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

	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/XMLUtils.java,
	  artifacts-common/pom.xml: New package. It will serve some classes and
	  utilities that are used in the artifact-database package as well as in
	  concrete artifact packages.

	* pom.xml: Added the artifacts-common package to be able to build all
	  packages using just the upper level pom file.

2011-02-01  Ingo Weinzierl <ingo@intevation.de>

	* artifact-database/pom.xml: Upgraded Restlet from version 2.0-SNAPSHOT
	  to the current stable version 2.0.4.

	* pom.xml: The SCM plugin will not check for local changes any longer.
	  Otherwise, we aren't able to build the project with outstanding
	  modifications.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/Standalone.java:
	  Set the max number of threads available for the REST server to 512. This
	  is a _WORKAROUND_ for Restlet-2.0.4 which seems to have a bug while
	  handling threads.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ImportResource.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactResource.java,
	  artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ServiceResource.java,

	  Renamed the packages of the Request and Response class that have been
	  changed from Restlet 2.0-SNAPSHOT to 2.0.4.

2010-03-25  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java: Added a
	  method 'getTimeToLive()' which retrieves the current artifact's time to 
	  live. The ttl of an artifact is available where ever a CallContext object
	  is existing.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Added new field ttl of an artifact to an PersistentArtifact.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Implemented 'getTimeToLive()' in CallContextImpl.

2010-03-22  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java:
	  Install a SLF4JBridgeHandler after logging is configured. This handler is
	  used to route incoming java.util.logging logs to SLF4J. In our case, we
	  route this incoming log to our log4j logger.

	* artifact-database/pom.xml: Added dependencies for SLF4J 1.5.11.

2010-03-22  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	  Issue208 (Remove special data of an 'out'-target before exporting
	  artifacts)

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java: Added a
	  'cleanup(Object context)' method to the interface definition of artifacts.
	  This method should be called before exporting an artifact and should
	  remove data stored on an artifact (or its current state) which have been
	  written by an 'out'.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
	  Default implementation of cleanup method - nothing is done here yet.
	  Override this method if an artifact needs to be cleaned before an export.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProxyArtifact.java:
	  Call cleanup method on the proxied artifact if proxied is existing.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Call cleanup method before exporting an artifact as xml.

2010-03-19  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	  Issue208 (Artifact gets a new identifier after being imported)

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java: Added a new
	  method setIdentifier(String identifier).

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
	  Default implementation of setIdentifier(String identifier) to give an 
	  artifact a new identifier.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Set a new identifier on an artifact after deserializing it.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProxyArtifact.java:
	  Set the identifier of the proxied artifact right after setting its own
	  identifier.

2010-03-19  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	  Issue208 (Artifact import)

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ImportResource.java:
	  New server resource to import an artifact from an incoming xml document.
	  The resource is available as /import and accepts xml documents send via
	  HTTP POST.

	* artifact-database/src/main/resources/sql/org-postgresql-driver.properties,
	  artifact-database/src/main/resources/sql/org-h2-driver.properties: New sql
	  statements to update an existing artifact.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  New method to import an artifact from an incoming xml document. The data
	  contained in this document is decoded using the secret.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  New method to store an artifact into database or replace it if an artifact
	  with the given id is already existing.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/StringUtils.java:
	  Removed method to convert a byte array into a string (this is done by
	  Apache's Hex class in commons codec) and added a new method to convert a
	  string into a byte array using Apache commons codec as well.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/RestApp.java:
	  Register ImportResource to webserver.


	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java,

	  Converted the author javadocs.

2010-03-16  Ingo Weinzierl <ingo.weinzierl@intevation.de>

	  Issue208 (Artifact export)

	* artifact-database/doc/example-conf/conf.xml: Added a section to configure
	  a secret string used to identify artifact imports for security reason.
	  Incoming artifact imports need to be identified with this secret, otherwise
	  the import should be blocked.
	  Xpath for this secret: '/artifact-database/export-secret/text()'

	* artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java:
	  New attribute 'exportSecret' and some code to read the secret from
	  configuration while application startup.

	* artifact-database/pom.xml: Added Apache Commons Codec library used to
	  encode/decode artifact data.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/StringUtils.java:
	  New utilities class for frequently used string operations.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	  Added some methods for exporting artifacts as xml documents. The data part
	  is base64 encoded. A secret key is used while encoding this data to verify
	  artifact imports, later.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	  Added an artifact loader interface used to deserialize artifacts. 
	  getArtifact() implements such an ArtifactLoader to return
	  PersistentArtifacts.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ExportResource.java:
	  New. ServerResource to export artifacts (innerGet). This resource is
	  available under "/export/{uuid}" via HTTP-GET request and returns an
	  artifact specified by uuid as xml document.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/RestApp.java:
	  Register ExportResource to webserver.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
	  Added method to export artifacts.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java:
	  Reset bootstrap after application startup.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CreateResource.java (innerPost): 
	  Put the XML-Document which was send by the client to the 
	  ArtifactDatabase.createArtifactWithFactory-Method.
	  
	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactFactory.java (createArtifact),

	  Changed Method signatures so that it is possible to put the Document
	  which will be send during the create Step of an Artifact to the Setup-Routine
	  of an Artifact.
	  Now it is possible to send further Informations to the Artifact using the 
	  XML-Document.
	  This is nessesary for manipoulating the Artifact e.g. setting Parameters 
	  which should only be displaied or e.g. put an Geometry-Object into the 
	  Artifact which should limit the displayed results.

	transfer information through the call level transparently.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	Adjusted default implementation of CallContext.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ProxyArtifact.java:
	New. A general proxy class for artifacts in artifact databases. This class uses 
	the extended call context semantics.

	The artifact calls (feed, describe, out, ...) are passed to a proxied artifact.
	If the proxied artifact decides to be replaced by some other artifact it has to
	to store a reference to the replacement artifact in the call context with
	putContextValue(ProxyArtifact.REPLACE_PROXY, my_new_artifact). After the call
	is finished the proxied object will change. This indirect callback mechanism is
	used to minimize side effects.

	The identifier() call is not forwarded to the proxied artifact to have a stable id.

	Limitations: This mechanism does not let you build real matroska (multi level)
	like artifact structures. This would only be possible if a kind of call context
	stack is introduced.

2009-09-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Refactored the persistent handling of the artifacts in the 
	artifact database. When an artifact is called (describe, feed,
	advance, out) a new CallContext is given instead of the
	old Object context. CallContext.globalContext() returns the
	old Object context now. CallContext.afterCall() may be
	called from inside describe, feed, advance and out to tell
	the artifact database what to do after the processing of
	the specific call.
	
	The accepted values are:
		- NOTHING    for doing nothing
		- TOUCH      for just update the last access time
		- STORE      for persisting the artifact.
		- BACKGROUND to signal that the artifact has started
		             a background operation.

	After the background operation the artifact has to call
	CallContext.fromBackground() to signal the artifact 
	database that the artifact needs to be touched or stored.

	!!! Without this call the artifact database assumes there
	!!! is still some background operation on this artifact
	!!! which prevents reclaiming resources

	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:
	New. New API to cope with background processing.

	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java:
	Replaced old Object context with CallContext context.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
	Adjusted.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
	For a better encapsulation of the persistence operations of the
	artifacts the database does not return artifacts any more. It delegates
	the describe, feed, advance and out call to internal structures.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabaseException.java:
	New. Simplifies handling of error conditions inside of artifact database.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
	Adjusted to new interface. Internally it handles the background API.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactResource.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/FactoriesResource.java,

	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactOutResource.java:
	Adjusted to new artifact database interface (which greatly simplifies things)

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
	Artifacts in background are not removed from database any longer.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: Little
	re-wirering need for new cleanup.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java: 
	Simplified to do the SQL stuff only. The most infrastructure stuff is now done
	in ArtifactDatabaseImpl.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Id.java:
	New. Helper base class to enable filtering of background artifacts by there
	database id.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
	Modified the INSERT statement to write the serialized artifact, too.

	New. The cleanup thread. It cleans up the artifact database
	perodically and calls the endOfLife() methods of the dead
	artifacts. Default cleanup interval is 5 minutes.

	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
	Tuned SQL a bit to fetch only a 50 artifacts in search for
	outdated artifacts to avoid too much memory consumption.

	* contrib/run.sh: Little tweak to work with more than one
	commons-pool version installed.

	* TODO: Removed remarks about the now implemented killer 
	thread and the moves XML stuff.

	* README: Changed text how to create a H2 database from
	command line only. XXX: This is still broken. The best
	way to set up the database by now is to start the Console 
	client, connect to the database, c&p the schema.sql 
	into the SQL text area and execute it.

	SQL statements for H2 database.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
	Artifacts are proxies/wrapped by an special Artifact implementation

	to be evaluated if a more direct concept like extending the Artifact API
	to store itself would be more robust for future implementations.
	TODO: Loading Artifact from db is not implemented yet.
