I.e., PUT /rdf-graphs/employees?graph=tag%3Aogbujic%40ccf.org%3A2010/consultant/56 Host: example.com <?xml version='1.0' encoding='UTF-8'?> <rdf:RDF .... no base named .... </rdf:RDF> We can't say that tag:ogbujic@ccf.org:2010/consultant/56 was used to 'retrieve' anything. > When we have http://example/x then adding /y changes the URI used to > retrieve the entity (5.1.3) entity from http://example/x to > http://example/x/y. > > So adding ?graph=GraphURI changes the URI used to retrieve the entity > (5.1.3) to GraphURI > > Admittedly weak, but then we are on the boundary of RESTful addressing > anyway. Ok. I agree that 1) we are on the boundary of RESTful addressing and 2) we want to support this behavior. I think we can go about it with the following wording that explains an intepretation of 5.1.2 since I don't think 5.1.3 would work in all cases: "In situations where there is no Base URI in the payload and a graph IRI is embedded, the RDF document that represents [AWWW] the networked RDF knowledge identified by the embedded graph IRI SHOULD be considered the retrieval context (5.1.2) [RFC3986]. Thus, the default base URI is the base URI of that RDF document." > Analogous situation: > > http://example/foaf is an info resource. > http://example/foaf#me is not contained in that info resource This is off topic, but according to the definition of a URI fragment, http://example/foaf#me *could* be contained in that IR: "The identified secondary resource **may be some portion or subset** of the primary resource, some view on representations of the primary resource, or some other resource defined or described by those representations.
