Re: http://www.ninebynine.org/RDFNotes/UsingContextsWithRDF.html Where you say: [[Using this approach, the number of triples will increase exponentially with he depth of context nesting.]] From: "Graham Klyne" <GK@ninebynine.org> > With the first level of nesting, I agree that the number of triples for N > statements increases to 4N. > > But with the next level of nesting, in the framework I was describing, each > of those 4N triples itself becomes 4-fold, for a total, of 16N. Next level > of nesting gives 64N. etc. No, no, no !!! Mathematically, nesting cannot work that way. Certainly a set, the quintessential container, doesn't work that way. The act of putting a RDF triple in a container must reify it only because that's the only way you can deal with it as an object; and containing something is dealing with it as an object. Once contained, anything inside the container becomes *opaque* to everything outside that container. So nothing you do to a container (for example pointing to it from somewhere else, or containing it again) can ever change whatever it is inside that container. You've got it that containing a container actually changes (in some bizarre way) what's inside that container. If the MT says that is the way RDF container's work, then the MT should be changed ... imho, of course. ... or have I misunderstood ?
