ISSUE-49: Is a graph an information resource

Is a graph an information resource

State:

CLOSED

Product:

Raised by:

Kjetil Kjernsmo

Opened on:

Description:

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.
