[Geoserver-devel] CoverageDimensionInfo and REST requests

I almost posted this to the user list, but once I figured out the issue this felt more appropriate in the developers’ list … so here I am …

To use the REST interface to update the CoverageDimensionInfo details for a coverage resource … i.e. populate the Coverage Band Details for a coverage layer … it appears that you have to explicitly specify the CoverageDimensionInfo class to get the dimensions list to be properly unmarshalled, like so:

curl -v -u admin:xxxxxx -XPUT -H “Content-type: text/xml” -d “truenewwordwindspeedmps” http://localhost:8080/geoserver/rest/workspaces/arthur/coveragestores/wind/coverages/wind

Otherwise, you get an com.thoughtworks.xstream.mapper.CannotResolveClassException: dimension caused by .

I believe this is handled with the @uml.property name=“dimensions” in

https://github.com/geoserver/geoserver/blob/master/src/main/src/main/java/org/geoserver/catalog/CoverageInfo.java

and similarly in

https://github.com/geoserver/geoserver/blob/2.6.x/src/main/src/main/java/org/geoserver/catalog/CoverageDimensionInfo.java

Not sure, though, as it’s late and I don’t really see a setter for the CoverageDimensionInfo list in CoverageInfo, just a getter.

Should this somehow be set to implicitly handle dimension as members of the dimensions list? Am I just missing how to form the xml for this?

Also, the org.geotools.util.NumberRange is used for the range property, and that seems potentially difficult to deserialize?

While I am on this topic, does anyone know if gsconfig python can handle the coverage dimension settings? I don’t see right away where it handles it, and perhaps it is because of the needed explicit class specification??

Full debug from the request without explicitly specifying the class name:
