- A standard way for site developers to point scutters and other SemWeb agents to resource descriptions (MGET support vs. response headers etc.) from a given URI
- A standard way to tell SemWeb agents how to find a site's SPARQL end point / query interface (something less complicated than UDDI, please).
(I only had a quick glance at the draft of the SPARQL protocol, maybe there is already a proposal on its way for the second issue.)
Oh yes, and the hash vs. slash issue, of course ;) (I guess that's somehow related to interoperability, too...)
But first: holiday!
