Nice, but if we define a mapping from a time point to a graph map, then how do you handle the case where a time point maps to multiple graph maps (for instance when you have auth* to consider)? > There exists a special temporal graph map, called the HTTPmap, such that > at any given point in time t, HTTPmap(t) maps a URI to the parsed RDF > graph of the document retrieved via an HTTP GET of the URI at the time > t. (if HTTP GET does not provide an RDF serialisation, then the mapping > is not defined on that URI). As above, doesn't consider auth*. At a single instant several different graphs may be associated with a specific URI. Thoughts? Best, Nathan
