Having a very lightweight ontology that defines a "feature" would be a great start. As a test case, I'd like to explore defining an RDF-Datacube dimension using such an ontology - the observation:featureOfInterest ontology. Personally, I dont think importing the full ISO 19150 ontology is a workable strategy - but one could have annotation properties (or an additional module) that handles the alignment to 19150. At the moment I see many attempts - but nothing accepted by the community at large. simply, one ought to be able to look at a dimension defined against a datatype, and/or set of objects, and discover that such objects a spatial features and thus the dimension supports operations relevant to spatial features - such as find the properties of such features and running a filter on them. I'm happy to help shepherd this Use Case through the emerging plan - and verify the solution is implementable. I need this in the context of other BP work OGC is involved in.
