A few initial comments (editorial): > >* Section 0 says "The *vocabulary* of a graph is the set of URIs that >it contains", while Section 1 says "All interpretations will be relative >to a set of URIs, called the *vocabulary* of the interpretation..." >This could be read as effectively saying that there are two vocabularies >of URIs (one for the graph and one for the interpretation), which I >don't think you mean, since, e.g., in the latter sentence you go on to >associate this "interpretation" with "an interpretation...of an RDF >graph". Right, thanks, that was an incomplete-editing bug, I will fix that. >* Section 3 (the anonymity lemmas) says "This means that there is no >valid RDF inference process which can produce an RDF graph in which a >single anonymous node occurs in triples originating from several >different graphs." This can be read in (at least!) two ways, one of >which is wrong. If I group "in which a single anonymous node occurs" >with "an RDF graph" (and don't also apply it with the rest of the >sentence), a counter-example is when I merge triples originating from >several different graphs, only one of which contains a single anonymous >node (the other graphs contain no anonymous nodes). The resulting graph >contains a single anonymous node from triples originating from several >different graphs, but since only one of those originating graphs >contained an anonymous node in the first place, everything is OK. >Something like the following would be clearer, I think: "This means >that there is no valid RDF inference process which can produce an RDF >graph containing a single anonymous node from several different graphs >each containing a distinct anonymous node." Right again. I meant that the triples came from two different graphs, ie one triple came from one graph and another triple came from a different graph, but they share an anonymous node in the merged graph. I will rewrite this more carefully to avoid misinterpretation. >More later. Thanks for feedback.
