Re: DCAT use case

This is basically what RDF Datacube does.. modulo the need to extend to add
a convention to bind a URI of a property name to a data element used in a
specific encoding.

I did an experiment to do just that in a hierarchical profile definition
for cituzen science applications of OGC standards.

So i would characterize this important Use Case as a sub case of exposing
dataset semantics, profile conformance of datasets and using 3rd party
vocabularies. In the latter case there is a need for extension

So.. is it a good idea to add terms to DCAT whose domain includes
qb:DataStructureComponent (but could be used by other vocabs) to specify
binding of properties to syntax platforms (default names)  or specific
bindings to idiosyncratic names used in individual data products.

I.e. whats the scope here as reinventing the wheel would be bad.. but it
would be necessary to specify the right type of wheel

Cheers
