2011-06-27     RELEASE 1.3

    NEW:

        * Bumped Restlet to version 2.0.7.

        * Use a Jetty server by default to handle HTTP requests.

        * Introduced a config option that allows to switch the HTTP server
          manually.

        * Introduced a config option that allows to limit the max number of
          threads used by the Restlet server. Defaults to 1024.

        * New REST interface to set the time-to-live of a Collection. This
          operation takes a java native long value or one of the strings "INF" -
          which means a Collection lives forever - or "DEFAULT" which means to
          reset the time-to-live to the default value configured in the artifact
          server.

        * New REST interface to set the name of a Collection.

        * Improved the ClientProtocolUtils to create documents for the operation
          to set the Collection's time-to-live.

        * The time-to-live of Collections is accessible in Collection objects.

        * Introduced a "creation" timestamp for CollectionItems.

        * Facets got a new property "index".


    FIXED:

        * A a new out() method is called that takes the "type" parameter specified in
          the REST url to specify the concrete output type. This parameter has
          not been used until now.

        * flys/issue75 Fixed SQL syntax error in trigger creation.



2011-05-13     RELEASE 1.2

    NEW:

        * Introduced "facets" as a new concept to select only parts/concrete
          types of an Artifact's output. E.g. a computation might return data
          that is used to draw two curves into a chart. With a "facet", just a
          single curve might be selected to be drawn into the chart.

        * New REST interfaces to set/get attributes of an ArtifactCollection.

        * Artifacts that live in ArtifactCollections don't die (because of their
          last_access time). A database trigger is used to update their
          last_access time if their owner ArtifactCollection is updated.

        * DatabaseCleaner removes outdated ArtifactCollections.

        * XML documents stored aside users, collections and collection items are
          compressed to reduce i/o costs.

        * Introduced a listener mechanism that is called if a context is
          created/closed. This listener might be implemented in concrete
          artifact packages.

        * Improvements in the ClientProtocolUtils: new functions to create
          special xml documents


    FIXED:

        * flys/issue8 (Cleanup des DatabaseCleaner schlägt fehl)

        * flys/issue9 (Fehler beim Laden von Artefakten - NO SUCH ARTIFACT obwohl Artefakt in DB vorhanden)


2011-03-30     RELEASE 1.1

2010-04-28     RELEASE 1.0

    New:

        * The path to database in the configuration can be relative to the
          central configuration document using ${artifacts.config.dir} as
          root.

        * New interfaces to export and import artifacts:

          HTTP GET  '/export/{uuid}'     returns an xml document representing
                                         the state of an artifact
          HTTP POST '/import'            takes an xml document that have
                                         been created by /export before

          The export mechanism uses a secret configured in the configuration
          to sign export documents. An artifact import fails if the
          signature of the xml document is not valid.

        * The time to live of an artifact is queriable at the CallContext
          object.


    Added:

        * JavaDoc documentation



2010-03-08     RELEASE 0.5


2010-01-27     RELEASE 0.4

        New:

		* Extended XML helper utilities a bit more
                * Added a new interface describing services 
                via XML documents via /services
                

2009-12-17      RELEASE 0.3

	New:

		* Extended XML helper utilities a bit
		* Added a new general proxy artifact.
		
	FIXED:

		* issue106: Konfiguration der GNV-Chart-Templates gehört nicht in das Artefakt-Framework

2009-11-13      RELEASE 0.2

	New:

        * Configuration documents can be made relativ to
        ${artifacts.config.dir}
 
        * Splitting up configuration of artifacts in depence to the
        product.

        * Added a first HOWTO for setting up the environemt and the
        artifact server

2009-10-07     RELEASE 0.1

	New:

	* Two sub projects: 'artifacts' and 'artifact-database'
	
		- 'artifacts' is a set of generic interfaces modelling 
		  the workflow to parameterize a process and producing
		  outputs.

		  An artifact is created via factories. It describes
		  itself via 'describe', it is parameterized via
		  'feed' and brought to new states with 'advance'.
		  Once able to produce output 'out' returns the
		  requested product.

		- 'artifact-database' is the default implemention
		  of the workflow described with 'artifact'.

	* artifact-database persists artifacts with a H2-database
	  [http://www.h2database.com] (default) or a
	  PostgeSQL 8.3+ database [http://www.postgresql.org/] (optional)

	* artifacts may spawn background threads to copy with long running
	  processes. After finishing work they are able to re-synchronize
	  themselves to the artifact database.

	* artifact-database is accessible via an HTTP REST server
	  implemented on top of the Restlet API http://www.restlet.org/
	  It has to be started as a service. Default TCP port: 8181

	  HTTP GET  '/factories'             returns list of available factories.
	  HTTP GET  '/create'                creates new artifact.
	  HTTP GET  '/artifact/{uuid}'       returns a description of an artifact.
	  HTTP POST '/artifact/{uuid}'       modifies an artifact ('feed', 'advance')
	  HTTP POST '/artifact/{uuid}/{out}' delivers output for an artifact.

	* artifact-database is configured with as XML file named conf.xml
	  (default placement in directory $HOME/.artitactdb, directory
	  may be changed with system property "artifact.database.dir")
