Re: RDF API 1.0 Draft / signing RDF content

Looks nice. I like how you've made a "triple" be a "resource". A couple
of comments...

1. Why is resource (and literal) creation bound to the model? Can a
resource or literal that is created in one model be used in a different
model? If not, why not? If so, should these be moved to RDFUtil, or
another interface that is used for resource management?

2. Also, it seems like you might want to be able to compose models
without combining them, at least for read-only operations. Compare
pseudo-SQL

  create view foo as select * from table1 union select * from table2

vs. 

  create table foo
  select * from table1 into foo
  select * from table2 into foo

Allows combining of data across arbitrary Model implementations.
