 2012-02-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
 
+	First steps to serve the data in cm if we are are gauges only.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  Fetch map gauge station -> gauge datum from backend for reference curve.
+
+	* src/main/java/de/intevation/flys/artifacts/math/LinearFilterFunction.java:
+	  New. Linear transforms another function.
+
+	* src/main/java/de/intevation/flys/artifacts/math/FilterFunction.java:
+	  New. Allows cascading functions.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WWAxisTypes.java:
+	  New. Classifier what kind of axis types are needed.
+
+	* src/main/java/de/intevation/flys/artifacts/model/NormalizedReferenceCurveFacet.java:
+	  Removed. Is now obsolete.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WW.java:
+	  Stores gauge station kms for start and end km if they are any.
+
+	* src/main/java/de/intevation/flys/artifacts/model/ReferenceCurveFacet.java:
+	  Should generate a WWAxisTypes classifier via side effect to the 
+	  call context.
+
+	* src/main/java/de/intevation/flys/artifacts/model/Calculation5.java:
+	  Figure out for each start/end km if its a gauge station and store this
+	  information in the result WWs.
+
+	* src/main/java/de/intevation/flys/exports/ReferenceCurveGenerator.java
+	  Uses the WWAxisTypes classifier now to generate the right data.
+	  TODO: Use the blackboard object.
+
+2012-02-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
 	* src/main/java/de/intevation/flys/artifacts/states/EnterLocationState.java:
 	  Removed superfluous imports.
