Hi Dan, et al

I spoke to Ed Parsons about this, and he advised that it was unlikely that
any specific DCAT profiles would be supported, but my thinking is that if
you support DCAT + some way of handling, say, statistical datasets using
datacube - that support would actually constitute a DCAT profile logically,
and could be described as such.

Happy to work with you therefore to describe what you do support AS
profiles, rather than push a profile at you :-)  It would make sense to
formalise goverance of geospatial data profiles via OGC - as a sub-profile
of GeoDCAT for example, if you support GeoDCAT (????)

I'm trying to track this issue across a number of statistical data fora -
but struggling to identify a center of gravity for the discussion - do you
have any suggestions
