Are Dimensions/Attributes Other Than Time and Elevation Possible

ClimateAttribute is an unknown keyword and will be ignored when the indexer.properties is read. The correct keyword to add additional dimensions to an Imagemosaic is AdditionalDomainAttributes.

The following should work adding a new Dimension in the Dimensions tab:

indexer.properties

TimeAttribute=time
AdditionalDomainAttributes=climatesource(climatesource)
PropertyCollectors=TimestampFileNameExtractorSPI[timeregex](time),StringFileNameExtractorSPI[climateregex](climatesource)
Schema=*the_geom:Polygon,location:String,time:java.util.Date,climatesource:String

climateregex.properties

regex=^.{4}

Note: String and Date dimensions are working properly, but due to a bug, Integer or Double Values are read as String only. That makes it not possible yet to query intervals. See this Bug Report.

Update: The bug has been fixed in 2.11.2.
