Hmm... quick question.
What's the latest and greatest wisdom within Linked Data for providing RDF metadata about an information resource?
To make it more challenging, the resource is:
- not an RDF document (so you can't just embed the metadata straight in there)
- not an (X)HTML document (so you can't just embed RDFa in there)
Let's say the resource is an image http://ex.org/image.jpg and we can't embed RDF directly.
Where should I serve my RDF metadata about the image and how should I serve it? Do I have to sacrifice dereferenceability? Do I have to use a "URI alias" with owl:sameAs? Do I have to disambiguate the "information resource" and the "non-information resource" (w/ something like foaf:isPrimaryTopicOf)?
(It seems that content-negotiation on http://ex.org/image.jpg is inappropriate since I'm not intending to return "equivalent" representations.)
Maybe it's a straightforward question?! Oh yep, refs encouraged!
Many thanks.
