HI David

Yes we are also looking into rule templates.

We have come up with - what we believe - is a very natural, intuitive and visually appealing way to author rules. And it is tailored for our specific domain.

One significant aspect of our work is that we are present drools authoring to end users - customers - rather than business users. Hence the importance of crafting a specialized UI, rather than the generic UI of Guvnor.

And FYI - are also including in the design some UI elements, for a future version, that will use Drools Chance features.

Can you point me to documentation - and ideally - samples around using APIs for the descriptor level?

Thanks

As a RETE network is being created, DRL Rules are parsed into an internal "descriptor" structure (a high level AST)
and then compiled into a RETE.

There are "APIs" to create rules at the descriptor level: this can then be "dumped" back into DRL.
To work at the DRL level directly, it's common to use parametric "templates".

If your internal (meta)model is object oriented, you could consider using DRL rules to write the translators :)

p.s. could you provide some more information about your use case? I'm doing some research on rule authoring
environments right now. Thanks!

Rules are DRL that is a String.

Where and how you choose to store the String is up to you.

Please try to explain what you want to achieve a little more.

HI all

Is there any samples or documentation for reading and writing of rules?

The user case is we are trying to build a custom Rule Editor, and thus would
like to write and read rules to/from our beans.

Thanks
