RDF Abstract Syntax: a strawman

I have written a brief strawman proposal defining an RDF Abstract Syntax.

http://www.openhealth.org/RDF/RDFAbstractSyntax.html


Triples are extended to add:

1) a context URI
2) an id
3) an index of the statement within the context in document order
4) a flag specifying whether the statement (7-tuple) is asserted within the
context

This is in response to some issues that have been raised as well as the new
N3 work ... particularly rdf:parseType="quote". Additionally the
<predicate,subject,object> match -either- URI reference -or- ?name, which
provides for quantification ... this is a pattern frequently used in RDF
query expressions.

This abstract syntax allows encoding of both RDF 'models' and RDF queries.

Comments welcome.
