Hi folks,

In the years since W3C's QL'98 workshop on Query languages
for the Web [1], there have been an increasing number of RDF 
query languages and implementations (hence this RDF IG mailing list).
Many RDF-based applications use one or more of these languages 
to express queries against repositories of RDF data.

The W3C Team, with input from the Semantic Web Coordination Group,
is currently drafting proposals for a 2nd phase of our 
Semantic Web Activity. One area of possible work we are considering
is RDF Query. This list has been pretty active in discussing 
the details of RDF query, its relationship with RDF rules, XQuery etc.,
as well as hosting practical interop collaboration, so we're 
circulating an early discussion draft for comments.

Did I mention yet that it is an *early* *draft*? For **discussion**?
Nothing is set in stone. Specifically, we haven't proposed anything
yet to W3C's Advisory Committee, and they've not approved anything.

The current draft is at [2]. EricP did most of the work on it. It will 
quite possibly change over the coming weeks, so please be sure to cite 
the $Revision number from the 'Status' section. The current version 
as I write this is 1.19. 

Issues we are still discussing include the schedule, relationship to
XQuery, OWL etc., and various other things flagged up in the document 
(CSS styled in Red at least in my browser). We are also interested 
in feedback regarding the extent to which mechanisms for remote access 
(ie. Web service interfaces; protocols) should be addressed 
by any standards-track Working Group we charter.

We would appreciate your comments by 20 November 2003, preferably to 
this (www-rdf-rules@w3.org) public, archived([3]) list. A separate 
discussion draft for work in the Rules area is also in preparation. The 
relationship between rules and query is an area we particularly 
welcome implementor feedback on. The thread earlier this week([4]) 
was both interesting and helpful btw.

Thanks for your input!

cheers,

Dan
