As I said in Carlsbad, for building real world apps, some kind of data management (variously known as 'provenance', 'contexts', and 'source') is essential. To address Rob's point, I don't see 4.2 as contradicting or extending the RDF data model. I'll be moving something very much like Andy's wording into the UC&R document when I next update it (very soon). Best, Kendall
