Re: invitation to try ImageSnippets

Hello Michael,

I have a question about the project. Where we can find a published paper or demo related to the project that show technical decisions taken and architecture?

Best regards.

| 
| The SPARQL endpoint with triples has the URL
| 
|  http://www.imagesnippets.com/sparql/images
| 
| and is updated once per day.
| 
| The "always current" version with quads has the URL
| 
| http://www.imagesnippets.com/sparql/dbpedia
| 
| and uses the image URLs as named graph URIs (the default graph is a
| copy of
| DPpedia for technical reasons).

| 
| Let me be sure I understand you: You took the image URLs and expected
| something
| else than an image to be served at those URLs ? Perhaps a 303 to the
| (X)HTML+
| RDFa document when such a content type is requested ? Wouldn't a
| "Link:" HTTP
| header with rel=meta be better ?
