-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Settings.java:
-	  An interface that describes a flat API for specifying settings for
-	  something. A Settings object can store one or more Section instances and
-	  defines a toXML() operation that should append a XML representation of
-	  itself to a given parent Node.
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Section.java:
-	  This interface is used to describe an API for storing and retrieving
-	  Attribute objects. Just as the Settings interface, it defines a toXML()
-	  operation that should append a XML representation of itself to a given
-	  parent Node.
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Attribute.java:
-	  The interface for concrete attributes in a Section instance. An Attribute
-	  is the placed on the lowest level of the Settings hierachy and should be
-	  used to save concrete key value pairs. Even the Attribute defines the
-	  toXML() operation described above.
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Output.java:
-	  Added a getSettings() and setSettings(Settings) operation.
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultOutput.java:
-	  A DefaultOutput is now able to store a Settings instance. It implements

-	  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

-	  Made it more compatible with mixed namespaces and mixtures of namespaces
-	  and no namespaces.
-
-	* artifacts/pom.xml: Set Java compatibility to 1.5. Why isn't this inherited

-	  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.

-	    2. the new value is "DEFAULT": this sets the TTL of the collection to
-	       the configured default value.

-
-	* 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.

-	  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:

-
-	* 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:

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

-	  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!

-	  paramter to AbstractCallContext constructors.
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/AbstractCallContext.java:
-	  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:

-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/State.java,
-	  artifact-database/src/main/java/de/intevation/artifactdatabase/state/AbstractState.java:
-	  Added a reference to an artifact to the parameterlist of describe().
-	  This is needed to retrieve other necessary information of an artifact.
-
-2011-04-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
-
-	* artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
-	  Internal granularity should be milliseconds and not microseconds.
-
-	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
-	  Forget last commit.
-
-2011-04-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
-
-	Fix for flys/issue9
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
-	  Removed code that checks for outdated artifact in user land.
-	   
-	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
-	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
-	  Do the check in the database and take into account if artifact
-	  is in a collection. XXX: Maybe this needs some speedup!
-
-2011-04-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
-
-	Fix for flys/issue8 (part 3)
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
-	  'NOT IN (NULL)' does not work. Used 'NOT IN (-666)' instead.
-
-2011-04-12  Ingo Weinzierl <ingo@intevation.de>
-
-	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
-	  Added a method that returns a document that is used to trigger the
-	  artifact's DESCRIBE operation.
-
-2011-04-07  Ingo Weinzierl <ingo@intevation.de>
-
-	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
-	  Added a method that creates documents used as input document for the
-	  Collection's out() operation.
-
-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.
-

-
-	* 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:

-
-	* 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:

-	* 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:

-	* 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:

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

-	  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,

-
-	* 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/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,

-	  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:

-	  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>

-	  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:

-2011-03-07  Ingo Weinzierl <ingo@intevation.de>
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:

-	  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

-	  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.

-
-	  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.

-	  artifact imports, later.
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
-	  Added an artifact loader interface used to deserialize artifacts.

-
-	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:

-
-	* 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/CreateResource.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.
-
-2009-09-12	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
-
-	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java(out):
-	out() is now called with an java.io.Outputstream to place
-	the output.

-	artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java,
-	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/OutRepresentation.java:
-	Adjusted.

-	is found by lookup.
-
-	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
-	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.

+	  Added a removeSection(Section) method.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Section.java:

+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Settings.java:
+	  An interface that describes a flat API for specifying settings for

+	  itself to a given parent Node.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Section.java:
+	  This interface is used to describe an API for storing and retrieving
+	  Attribute objects. Just as the Settings interface, it defines a toXML()
+	  operation that should append a XML representation of itself to a given
+	  parent Node.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Attribute.java:
+	  The interface for concrete attributes in a Section instance. An Attribute
+	  is the placed on the lowest level of the Settings hierachy and should be
+	  used to save concrete key value pairs. Even the Attribute defines the
+	  toXML() operation described above.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Output.java:
+	  Added a getSettings() and setSettings(Settings) operation.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultOutput.java:
+	  A DefaultOutput is now able to store a Settings instance. It implements
+	  getSettings() and setSettings(Settings) defined in the Output interface.
+
+2011-12-09	Felix Wolfsteller	<felix.wolfsteller@intevation.de>

+	inter-facet pre-rendering communication ('blackboard') phase.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/ArtifactAndFacet.java:
+	  New class, keeping together an artifact and a facet (thus, should
+	  only have a short live span). Only implementation of the new
+	  DataProvider interface.
+
+2011-11-30	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Extended CallContext to also act as a blackboard/service broker.

+	  New interface to prepare inter-facet pre-rendering communication
+	  phase ('blackboard').
+
+2011-11-30	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Prepare inter-facet pre-rendering communication ('blackboard') phase.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Facet.java
+	  (getDataProviderKeys,provideBlackboardData): Extended interface to
+	  allow easy integration of blackboard mechanism (inter-facet
+	  pre-rendering communication).
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultFacet.java
+	  (getDataProviderKeys,provideBlackboardData): Trivial implementation.
+	  The DefaultFacet will not talk to other facets during inter-facet
+	  pre-rendering ("blackboard") phase. Cosmetics, docs.
+
+2011-11-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/XMLUtils.java:
+	  Changed Ingo's last commit to a more conservative notation (no auto-boxing).
+	  Strangely the flys-client does not compile for me with the auto-boxed

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

+	  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,
+	  artifact-database/src/main/java/de/intevation/artifactdatabase/CollectionCallContext.java,
+	  artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactCallContext.java:
+	  The CallContext got a new method isInBackground() that determines, if
+	  the Artifact or Collection (currently not implemented) has started a
+	  background thread and is locked.
+

+	  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.

+	* 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

+
+	  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;

+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java,
+	  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.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionResource.java:

+
+2011-06-06	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	flys/issue75
+
+	* artifact-database/doc/schema-h2.sql: Fixed SQL syntax error in trigger creation.
+
+	* 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:
+	  The deferred output got a new out() method that takes the 'type'
+	  parameter specified in the url part.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactCollection.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:

+	  XMLUtils.xpathString() returns empty string not null.
+
+2011-04-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	flys/issue65: Added Jetty HTTP server as a replacement option to foster
+	better scalability. Needs testing.

+	  Pass restlet context to super constructor.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/JettyServer.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.

+	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/HTTPServer.java:
+	  New. Interface to run an HTTP server. Enables the system to run on different
+	  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
+	  to mitigate flys/issue65.
+
+2011-05-13  Ingo Weinzierl <ingo@intevation.de>
+
+	Tagged as RELEASE 1.2
+
+	* Changes, NEWS: Changes and news for release 1.2
+
+2011-05-12  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
+	  The method that is used to create the request document for querying
+	  charts will now take a document which might contain parameters to adjust
+	  chart settings (e.g. chart height/width).
+
+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!
+
+artifact-database/src/main/java/de/intevation/artifactdatabase/transition/TransitionEngine.java
+
+2011-04-28  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:
+	  States have now a method getData(String) to retrieve just a single StateData object.
+
+2011-04-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
+	  Added a function that creates the document that is used to set the
+	  attribute of a CollectionItem (setCollectionItemAttribute() operation).
+
+2011-04-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
+	  Bugfix: Do not create empty XML documents and save those into database -
+	  exceptions while serialization/deserialization have been the result of
+	  this.
+
+2011-04-26  Ingo Weinzierl <ingo@intevation.de>
+
+	* 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/Backend.java:
+	  New methods for querying and updating attributes of collections.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionResource.java:
+	  Enabled the request dispatcher to handle requests specific to collection
+	  attributes and collection item attributes.
+
+	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
+	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
+	  New statements for querying and inserting attributes of collections.
+
+2011-04-26  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java,
+	  artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java,
+	  artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	  Changed the names of the method names that set and retrieve the
+	  attributes of collection items (e.g. getCollectionAttribute() ->
+	  getCollectionItemAttribute()).
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionResource.java:
+	  Modified method calls based on the changes above.
+
+2011-04-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/state/Output.java,
+	  artifact-database/src/main/java/de/intevation/artifactdatabase/state/DefaultOutput.java:
+	  Added a method to add further facets.
+
+2011-04-14  Ingo Weinzierl <ingo@intevation.de>

+	  configured).
+
+2011-04-14  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:
+	  Added a setup() method as in the other factories.
+
+2011-04-14	Sascha L. Teichmann	<sascha.teichmann@intevation.de>	
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
+	  Added instance variable to hold a call context listener.
+
+2011-04-14	Sascha L. Teichmann	<sascha.teichmann@intevation.de>	
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
+	  Call the postCall() methods of all CallContextes. Removed superfluous context
+	  paramter to AbstractCallContext constructors.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/AbstractCallContext.java:
+	  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:
+	  adjusted to guarantee that super.postCall() is called.
+
+2011-04-14	Sascha L. Teichmann	<sascha.teichmann@intevation.de>	
+
+	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:

+	
+2011-04-14  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:
+	  Added a reference to an artifact to the parameterlist of describe().
+	  This is needed to retrieve other necessary information of an artifact.
+
+2011-04-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
+	  Internal granularity should be milliseconds and not microseconds.
+
+	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
+	  Forget last commit.
+
+2011-04-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Fix for flys/issue9
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	  Removed code that checks for outdated artifact in user land.
+	   
+	* artifact-database/src/main/resources/sql/org-h2-driver.properties,
+	  artifact-database/src/main/resources/sql/org-postgresql-driver.properties:
+	  Do the check in the database and take into account if artifact
+	  is in a collection. XXX: Maybe this needs some speedup!
+
+2011-04-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Fix for flys/issue8 (part 3)
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
+	  'NOT IN (NULL)' does not work. Used 'NOT IN (-666)' instead.
+
+2011-04-12  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
+	  Added a method that returns a document that is used to trigger the
+	  artifact's DESCRIBE operation.
+
+2011-04-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifacts-common/src/main/java/de/intevation/artifacts/common/utils/ClientProtocolUtils.java:
+	  Added a method that creates documents used as input document for the
+	  Collection's out() operation.
+
+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:

+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

+	  false.
+
+2011-03-09  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/transition/TransitionEngine.java:

+
+	* 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,

+2011-03-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java,

+	  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>

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

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

+	  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:

+
+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
+	  string to the collection node in listCollections(). A
+	  NullPointerException is avoided!
+
+2011-03-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifact-database/src/main/resources/sql/org-h2-driver.properties,

+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	  Changed the method signature of createCollection(). The Backend needs

+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
+	  Implemented the interface method createCollection().
+

+	  Adapted the signature of deleteUser(). These methods don't await a User
+	  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:

+
+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/rest/BaseOutResource.java:
+	  New. Abstract class that should be used as the base class for the

+	  correct methods in the artifact database.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CollectionOutResource.java:
+	  New. The OUT Resource for collections. It implements the two abstract
+	  methods of BaseOutResource.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactOutResource.java:
+	  This class inherits from BaseOutResource now. The most code has been

+
+	  Issue208 (Artifact export)
+
+	* artifact-database/doc/example-conf/conf.xml: Added a section to configure

+	* 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

+	  of an Artifact.
+	  Now it is possible to send further Informations to the Artifact using the

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

+
+2009-11-23	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:
+	Added a context dictionary accessible through putContextValue(key, value)
+	and getContextValue(key). Purpose is make artifact calls stackable and
+	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.

+2009-09-14	Tim Englich	<tim.englich@intevation.de>
+
+	* src/main/java/de/intevation/artifacts/ArtifactFactory.java Edited:
+	Make Objects Serializable 
+
+	* src/main/resources/sql/org-h2-driver.properties: 
+	Bug Fixed in SQL-Query
+
+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/OutRepresentation.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CreateResource.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.
+
+2009-09-12	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java(out):
+	out() is now called with an java.io.Outputstream to place
+	the output.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/OutRepresentation.java:
+	Adjusted.
+
+2009-09-11	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifact-database/doc/example-conf/conf.xml: Added
+	sleep time for cleanup thread.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java:
+	Start cleanup thread at startup.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	Make artifact restoring bit more robust, added ref to
+	cleanup thread to do an immediate cleanup when dead artifact
+	is found by lookup.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
+	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.

+
+	* artifact-database/doc/artifactdb-example-conf.xml: removed
+	* artifact-database/doc/example-conf/conf.xml: Re-added here.
+
+	The configuration is now found in a subdirectory set by the
+	system property 'artifact.database.dir'. If this property is
+	not set '~/.artitactdb' is used. This directory should contain
+	a file 'conf.xml' with the configuration details.
+	  If the artifact database is started as a standalone the config
+	directory is searched for 'log4j.properties' to configure the
+	logging.
+	  The H2 database is also search in this directory with the

+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	Implemented loading of artifacts from database. If the last access of an

+	for examples.
+
+	* artifact-database/pom.xml: Cleaned up XML.
