The registry schema has to be completely DM compatible. At the moment, we've
embedded our own way of describing the contents of a resource or service
(basically listing tables and columns with associated ucds) but this is only
a stop-gap. When the DM has a catalog model it (or rather its xsd
representation) can be imported into the registry schema (data collection
and possibly sky service) and the simplistic content structure can be
replaced with a DM equivalent.
Cheers,
Tony.
