My comments for the F&R document are below (per my ACTION) This is probably a nit pick, but section 2.3.2 Description probably could be re-written to give better context regarding checking for the absence of a binding in contrast to 'classical' (open-world) negation: .. can require the checking of whether certain triples (or terms) do or don't exist in the graph. Checking for the absence of triples is a form of negation called Negation by failure (or default negation). Such an interpretation of negation is in contrast to one that is based on there being a logical derivation (the open-world assumption) and is the approach traditionally used by database systems. 4 Update The Working Group has resolved to specify a SPARQL/Update language, but may also pursue a HTTP based graph update via the protocol. This issue is orthogonal to the SPARQL/Update language. Whether or not there will be a concrete mapping between SPARQL/Update and HTTP based graph update is currently under discussion in the working group. I'm not sure if this section in red is not subject to comment (because it came from a resolution for instance), but I suggest the following re-wording: .. may also pursue a native HTTP protocol abstraction for updates to an RDF dataset. And in (4.2.3 Existing implementation) The 4Suite content repository supports the use of HTTP PUT to either directly update a named graph or to update XML an document that is mirrored into RDF via a GRDDL-like mechanism. -- Chimezie =================================== 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 (2008).
