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

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

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

	* TODO: Implement Step-Back in advance operation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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