ISSUE-49: Is a graph an information resource http://www.w3.org/2009/sparql/track/issues/49 Raised by: Kjetil Kjernsmo On product: SPARQL 1.0 states that the graph URI does not point to a information resource. The consequences of this needs to be explored particularly for the HTTP protocol update. This issue has been discussed on the mailing list, see e.g. http://lists.w3.org/Archives/Public/public-rdf-dawg/2009OctDec/0105.html httpRange-14, at http://www.w3.org/2001/tag/issues#httpRange-14 which is important to the semweb community and should therefore be taken as a normative reference for this group, states that If an "http" resource responds to a GET request with a 2xx response, then the resource identified by that URI is an information resource; Thus, it seems that a URI that identifies an information resource cannot be used as a graph URI, even when GETting that URI will result in that the same information content is returned. Concretely, this seems to imply that if you have a document http://example.org/foo.rdf you cannot import this into a quad store with http://example.org/foo.rdf as the graph name, since it is an information resource. Moreover, if you did, you cannot return a 200 if has been imported, it would have to return a 303. This would add a lot of confusion and complexity.Received on Tuesday, 20 October 2009 11:22:57 UTC
