+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added a
+	  method getDataAsLong that returns a Long representation of a data item or
+	  null if no such data item is existing or it cannot be parsed as Long.
+
+	* src/main/java/de/intevation/flys/utils/FLYSUtils.java: Added a function
+	  that returns the selected reference gauge (specified by 'reference_gauge'
+	  parameter) of a FLYSArtifact.
