Eric Prud'hommeaux and Dan Brickley - eric@w3.org and danbri@w3.org - ha ve
been working on querying. I believe they have an implementation, but I don't
have a pointer to it - eric will be in later.

  Thanks for the pointer to the W3C Query workshop. 
  I have a copy of the proceedings and checked out
  most of the work that seemed relavant before
  I began.
  I also checked out a couple of schema based query languages
  such as OQL. These did quite suit my needs.
  I ended up doing something tuned to matching patterns
  in a labeled, directed graph (RDF's fundamental data
  model). Any pointers to graph based query languages
  would be especially appreactiated.

  The W3C has just announced the formation of an XML Query Working Group
  (http://www.w3.org/XML/Activity.html#role), but I suspect this group will
  initially be focused on a general XML query language.

  I am working on a query language for RDF. I was wondering if
  anyone else in this group is interested in this sort of thing
  or if anyone can suggest pointers to related work?
