I see it differently. The semantics of POST are to accept the entity enclosed as a 'subordinate'. The analogy of the relationship between a file and a directory is used to explain what is meant by a subordinate. This suggests an additive operation. The semantics of PATCH - on the other hand - are actually more inline with the general intent of the SPARQL Update language itself, since it says "With PATCH, however, the enclosed entity contains a set of instructions describing how a resource currently residing on the origin server should be modified to produce a new version" So it seems to me that the PATCH operation is equivalent to a SPARQL Update request at 'graph-level' granularity and that additive operations on an RDF graph (i.e. POST currently) are a subset of this. -- Chime =================================== P Please consider the environment before printing this e-mail Cleveland Clinic is ranked one of the top hospitals in America by U.S.News & World Report (2009).
