The index allows preservation of statement order as if each RDF <Description> defines a container, and folds the RDF concept of container directly into the RDF Abstract Syntax." Is it implicit that a single context only contains data from one document? If not, how can 'document order' be preserved? What if a second document adds triples to a container? Similarly, if the data at a given URI change, and are obtained again, can/should they be merged into the existing context with the same base URI (or is there a mechanism by which a new, different context URI would be generated?).
