>Some comments on the 28-Aug MT draft. Many thanks, especially for the suggestions for rewording to make the meanings clearer. I will take these into account in rewriting. Some of them are already fixed. One point; there is indeed rampant confusion in the 28 Aug draft between NTriples terminology (eg <uriRefs>) and RDF graph terminology, a product of my own confusion and the change made at the F2F. I am currently trying to get this completely rationalized, so thanx for the pointers. >5th para: I take it the discussion of time-varying referents is not >intended to preclude resources with time-varying attributes? (E.g. >a vehicle whose current position can be a function of time.) Er.....no, it *is* intended to preclude those. One could imagine having 'current position' being described in RDF, of course, and being constantly updated, but that's what I meant by any particular piece of RDF being a 'snapshot'. >Next para: I struggled with this; "the same interpretation ... >also assigns truth values to graphs with anonymous nodes", etc. I >don't see how this works. The Interpretation defined for ground >graphs seems to depend on having a direct model theoretic >interpretation for the nodes mentioned (if E is <s p o>, I(E) = true >iff <I(s),I(o)> is in IEXT(I(p))... ) Yes, but the point is that while the interpretation doesnt assign any denotation to anonymous nodes, it does specify the truthvalue of a graph containing anonymous nodes. I will try to say it more clearly. > >The next condition is well-mangled by my browser; is that the >intersection of "ICEXT(I(rdfs:ConstraintResource)) and IP" ? Yes. Im learning how to write HTML (new experience for me! ) using DreamWeaver, and this stuff will all be laid out in tables in the next version.
