Sorry, If I can't see it in a diagram, then I don't believe it. It would help if you would indicate a specific point of mine that you can't follow. I've tried to phrase my points in various ways and would be happy to learn what aspects of my phrasing are throwing things off. BTW, the use of the term "model" earlier in your message made me revisit the thread from last month and Sergey's posting [2]. He makes the point that there is only one model which is "the model" which contains all the statements/triples in existence. It corresponds to the set of Statements which is described in the formal model in the M&S. Sightings of these triples can occur in many places of which places on the web are of most interest to me. An RDF/XML document is a specific place that members of the universal Statements set can either occur in and/or be referred to. The M&S provides a way to capture the fact that these occurences or references happened at a specific place on the web. The URI portion of the reified resource identifier provides this information. In addition, the M&S provides a way of tracing the syntactic context of a statement occurrence to a finer level by associating all the statement occurrences in a particular RDF/XML Description element to a Bag. The reified statement resource and the Description Bag are also used for other purposes than providing traceability and context. Since they are resources, they can be the objects of statements and this is the primary way that the M&S discusses their utility. I happen to think that it is a happy happenstance that they can also be used to provide other critical capabilities for document webs. Hope this helps even if there aren't any pictures :-) Gabe [1] http://lists.w3.org/Archives/Public/www-rdf-logic/2000Nov/0103.html [2] http://lists.w3.org/Archives/Public/www-rdf-interest/2000Oct/0180.html > > Seth Russell -- --------------------------- http://www.jfinity.com/gabe
