+2011-03-03  Ingo Weinzierl <ingo@intevation.de>
+
+	* artifact-database/doc/example-conf/conf.xml: Added a node that
+	  configures a default artifact collection factory.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java:
+	  The artifact collection factory (currently just a single one) is read
+	  from configuration and setup with its parameters.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
+	  Fetch the configured artifact collection factory from bootstrap.
+
