For well over two years now, Oracle, IBM, ILog, Fair-Isaac, and many others
have been involved in an effort at W3C to make a
standard XML format for rules, so people can move their rules between
different kinds of systems (including prolog systems and production-rule
systems) and publish them for re-use on the Web. We're not trying to do
anything terribly complex, just find the commonalities between different
systems and build a format around those.
Since the common core (intersection) of commonly used rule languages is so
small, we've decided to pick
a few points of standardization, or "dialects". We're now done with the
design of the first of these, which we call the "basic logic dialect"
(BLD).
BLD corresponds very roughly to pure prolog, and we're very interested
in getting some feedback from people before we continue along the
standards process. I suspect some folks on this list would have good
insight.
The latest draft BLD specification is here:
http://www.w3.org/TR/rif-bld/
We also have our very first public working draft of the Production Rule Dialect
specification at
http://www.w3.org/TR/rif-prd/
We'd appreciate comments by 19 September, and please send them to
[EMAIL PROTECTED], which is a publically-archived mailing list.
We would like comment on editorial style ("I couldn't really understand
section 4.2.1 because...") as well as the more technical and
theoretical.
