This message is being sent primarily to keep odp-rdf-announce alive as a
yahoo group. We have not changed the RDF file format, and currently
have no plans to do so.

There is a relatively new file, http://dmoz.org/rdf/tags.html, which
provides a listing of each tag that we use in each of the RDF files.
This is produced by reading the RDF files, and it highlights any tags that
it doesn't expect. By checking this file weekly, you can easily see any
tags that have changed.
