RE: Is use of Data Cube Vocabulary for an observation-less catalog considered harmful?

Yes, that's right.

The ways in which I'm extending it seemed irrelevant to my question, so I didn't get into it.  FWIW, I'm exploring whether cataloging with deep semantics that describe the real-world relationships between the measures and dimensions can lead to better means for search and mashup.

Yes, I know the Ontology Police won't come get me ;-) - I'm just concerned about mucking up the ecosystem, creating usage ambiguity where there was none before, simply because no one had considered this usage before.
