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")
