+2011-11-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/meta-data.xml: Added a datacage node that represents a
+	  kilometer WMS layer.
+
+	* doc/conf/conf.xml: Added a new Artifact WMSKmArtifact.
+
+	* doc/conf/themes.xml: Added a style for 'floodmap.kms' facets.
+
+	* doc/conf/artifacts/winfo.xml: Defined 'floodmap.kms' as valid floodmap
+	  facet.
+
+	* src/main/java/de/intevation/flys/artifacts/model/FacetTypes.java: Added
+	  a 'floodmap.kms' facet.
+
+	* src/main/java/de/intevation/flys/utils/FLYSUtils.java: Added a method to
+	  determine the srid of a river based on its name.
+
+	* src/main/java/de/intevation/flys/artifacts/WMSDBArtifact.java: New. This
+	  Artifact should act as base Artifact for WMS layers that represent data
+	  from database datastore.
+
+	* src/main/java/de/intevation/flys/artifacts/WMSKmArtifact.java: New. This
+	  Artifact is used to generate facets for kilometer WMS layers.
+
+	* src/main/resources/messages.properties,
+	  src/main/resources/messages_de_DE.properties,
+	  src/main/resources/messages_en.properties,
+	  src/main/resources/messages_de.properties: Added default descriptions
+	  for 'floodmap.kms' facets.
