ldp-ISSUE-90 (Named Graph): An LDPC/LDPR is a Named Graph [Linked Data Platform Spec]

Raised by: Alexandre Bertails
On product: Linked Data Platform Spec

An LDPC/LDPR acts as a Named Graph (now defined in RDF 1.1 [1]). An HTTP GET on an LDPR URL should return its representation, and *nothing* else.

The specification currently says:
[[
4.3.3 LDP servers MUST provide a text/turtle representation of the requested LDPR [TURTLE].
]]

I propose that the specification explicitly refers to RDF Named Graphs and makes the constraint on the GET explicit.

This does not prevent one to later define a service (eg. SPARQL) which would allow a user to retrieve the representations of an LDPC and its LDPR in one single request.

Also, all the examples (eg. 1, 2, 9, etc.) with GETs on LDPCs must not return the content of the "contained" LDPRs. They should be rewritten in terms of several GETs, one for the LDPC and one for each LDPR.

Alexandre.
