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.

Mark, Andrew, Guys,<br>
<br>
Yes working with DRL may be better for Drools indeed. But the only way I<br>
see this working is by implementing this directly in the code of Drools.<br>
That's not practical for me, hence I "simply" export/import the rules<br>
in/from XML. This way I can focus on the translation.<br>
<br>
If someone would give me pointers on an easy way to work with DRL, I'd do<br>
that of course.<br>
<br>
I assume you already had discussions on XML (or anything more structured<br>
and widely spread than DRL) as working format so I won't be going there :)<br>
<br>
All the best,<br>
Pierre<br>

Sorry someone just read that sentence back to me, and it probably read<br>
very wrong.<br>
<br>
Let me start again. First up great work, it's good to see any<br>
interchange work happening, it's not easy stuff. And I can't wait for us<br>
to figure out how to get this working directly against our more recent<br>
DRL :)<br>
