Re: invitation to try ImageSnippets

Hello Margaret,

In the previous message sent by Michael, he said that the endpoint SPARQL is updated once per day. I guess that the approach used in the project is a batch update approach. I am very interested in the way used for to do this. Other colleagues and I, we are studying some approaches developed for incremental update of RDF graphs in linked data context, more specifically, RDF graphs updated from a legacy relational database.

Best regards.

| Hello Yusniel,
| 
| Pat Hayes and I have published a paper related to the small
| lightweight
| ontology that
| we use for describing the images within the application, though we
| have now
| deviated somewhat from some of our initial thoughts described in that
| paper.
| 
| 
| I could still send you a link if this is the kind of information you

| interested in.
| 
| If not, perhaps I could try to answer more specific questions about
| the
| project.
|

| | 
| | 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
| | ?
