I am now...

I agree with Jonathan, it seems like a great opportunity to make ODC PDDL
more usable - by providing

   - A URI that associates specific versions of the PDDL with a release of
   data
   - A template for adding the license to RDF specifically (that may have to
   include the specific text).

Hello everyone.
