Ok, thanks for clarifying.

Going back to diagram of resolution precedence: | .----------------------------------------------------. | | | .----------------------------------------------. | | | | | .----------------------------------------. | | | | | | | .----------------------------------. | | | | | | | | | <relative-reference> | | | | | | | | | `----------------------------------' | | | | | | | | (5.1.1) Base URI embedded in content | | | | | | | `----------------------------------------' | | | | | | (5.1.2) Base URI of the encapsulating entity | | | | | | (message, representation, or none) | | | | | `----------------------------------------------' | | | | (5.1.3) URI used to retrieve the entity | | | `----------------------------------------------------' | | (5.1.4) Default Base URI (application-dependent) | `----------------------------------------------------------' The only way the absolute IRI would be otherwise would be if (5.1.2) applied. This would require an intuitive interpretation of the following (with respect to the URI embedding mechanism we are using for indirect reference): [[[ For a document that is enclosed within another entity, such as a message or archive, the retrieval context is that entity. Thus, the default base URI of a representation is the base URI of the entity in which the representation is encapsulated. ]]] I can understand how the behavior without 'filling in' 5.1.2 for the HTTP RDF protocol would be counter intuitive for documents where the graph IRI is embedded in the query component but the payload does not have an embedded Base, but I can't think of a cohorent piece of text that describes how the payload can be said to be 'enclosed' or 'encapsulated' within (presumably) a representation of http://otherserver/consultant/56.
