Re: "DOM" for RDF?

Richard,

I think Graphity is close to what you're looking for:
https://github.com/Graphity/graphity-browser
It supports SPARQL Protocol and Graph Store Protocol, content
negotiation, XSLT transformations of RDF output and RDF input user
interface using RDF/POST (http://www.lsrn.org/semweb/rdfpost.html).

We are also working on a multi-tenant solution, which turns Graphity
into application platform, on which Linked Data sites can be
configured declaratively (via user interface) over SPARQL endpoints.
