(It's not meant as a personal attack; I wouldn't be saying this if you were representing MIT or an implementer or a group of users.)

Yes, some additional R&D is usually necessary.

I agree.

I question whether standardization in W3C is the right way of generating this attention. I believe it is not, due to the danger of poisoning the big arena with a poor design.

As I understand the history, XML was made by throwing away most of SGML. Subsetting an existing standard based on deployment experience is less risky than creating something new.

I'm glad you asked. Let me quote what I wrote two years ago for the workshop that kicked off this WG's work:

[[
Managing context, provenance and graph updates are extremely important in almost any RDF application. The solution is the Named Graphs data model. It is already part of the SPARQL Recommendation, is widely implemented also outside of SPARQL, and generally well-understood. It should be elevated to a separate Recommendation. Besides codifying existing practice, this would be a welcome support for those practitioners who are trying to improve the general state of provenance tracking and metadata on the RDF-based Web and who are currently fighting a somewhat uphill battle because of Named Graphs' relative obscurity. Furthermore, a Named Graphs standard could galvanize research on the upper layers of the Semantic Web stack, where the availability of rich context information, along with a standard model for its representation, is a key requirement.

Codifying existing practice, and putting W3C's clout behind something that we already know works well, is sometimes all that the community needs to proceed, IMO.

There's more that could be said in response to your question, but I'll leave it at that for today.

All the best,
Richard
