From that we have a DRL "dumper" that generates DRL, enabling the RIF->DRL

Mark, Andrew, Guys, Yes working with DRL may be better for Drools indeed. But the only way I see this working is by implementing this directly in the code of Drools. That's not practical for me, hence I "simply" export/import the rules in/from XML. This way I can focus on the translation. If someone would give me pointers on an easy way to work with DRL, I'd do that of course. I assume you already had discussions on XML (or anything more structured and widely spread than DRL) as working format so I won't be going there :) All the best, Pierre On 09/02/2011 16:46, Mark Proctor wrote: > On 09/02/2011 08:40, pdl at agh.edu.pl wrote: >> Hi all, >> >> I've been working on translators between RIF-PRD, DroolsML and JessML. >> I've put the translators in the form of XSLT stylesheets on the following >> web site along with samples of rules written in the above languages.

Sorry someone just read that sentence back to me, and it probably read very wrong. Let me start again. First up great work, it's good to see any interchange work happening, it's not easy stuff. And I can't wait for us to figure out how to get this working directly against our more recent DRL :) Mark > Mark >> I look forward to hearing from you, >> Pierre >> _______________________________________________ >> rules-dev mailing list >> rules-dev at lists.jboss.org >> https://lists.jboss.org/mailman/listinfo/rules-dev >> >> > > _______________________________________________ > rules-dev mailing list > rules-dev at lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-dev > > _______________________________________________ rules-dev mailing list rules-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev

Drools has an internal canonical model that we use to round trip rules between the syntaxes we support. The best way of supporting "RIF" in Drools is to simply add a parser that parses RIF and populates the canonical model. From that we have a DRL "dumper" that generates DRL, enabling the RIF->DRL translation. Also, if we create a RIF "dumper", one can then generate RIF rules from the canonical model, enabling DRL->RIF translation. That assumes that there is a 1-to-1 semantic mapping between RIF and DRL (I believe there is, but didn't checked). Do you mean that all of RIF can be expressed in DRL? Then I'd agree. But you can't express all of DRL in RIF. -W
