Add prefix & namespace metadata to each file

Add prefix & namespace metadata to each file

[ktk]

• dcterms:description
• rdfs:isDefinedBy vs. rdfa:uri: From what I read they aim at the same thing IMO. I would prefer rdfs: as I rarely see the rdfa one in the wild.
• dbo:filename sounds close enough!

I think this would be a "big" change to what this package provides. The triples from the ontologies are currently provided as-is, nothing gets added or removed or modified.

What about providing a separate file with all the metadata as RDF instead? It could provide the base IRI, prefix, and filename.

[ktk]

That would be perfectly fine for me. Sole question is what URI would we use as subject for this. In RDFa initial context it's a blank node, maybe that's the best bet. But then we should probably also add a class as in the example, they use rdfa:PrefixMapping

Alright so something like:

[] a rdfa:PrefixMapping ;
  dcterms:description "The W3C Linked Data Platform (LDP) Vocabulary" ;
  rdfs:isDefinedBy <http://www.w3.org/2012/ldp> ;
  rdfa:prefix "ldp" ;
  rdfa:uri "http://www.w3.org/ns/ldp#" .

and one more thing for the local filename I guess

Looks good! For file the only ontology I know is infamous Nepomuk File Ontology, which was once part of KDE: http://oscaf.sourceforge.net/nfo.html#nfo:fileName.

Could not find something else with a quick search for file*

What about dbo:filename?

More questions on this example:

[] a rdfa:PrefixMapping ;
  dcterms:description "The W3C Linked Data Platform (LDP) Vocabulary" ;
  rdfs:isDefinedBy <http://www.w3.org/2012/ldp> ;
  rdfa:prefix "ldp" ;
  rdfa:uri "http://www.w3.org/ns/ldp#" ;
  dbo:filename "ontologies/ldp.nq" .

• What's the difference between the content we would put in rdfs:isDefinedBy and rdfa:uri?
• Where can I find what to put in dcterms:description?

My idea is to add these to https://github.com/zazuko/rdf-vocabularies/blob/master/overrides.js or to a file similar to this one, to then be able to generate the above data.

From triple POV looks good to me!
