<div>Depending on your model, it may be better to create a DSL as an intermediate language. That way you have a simplified language, which you control, to parse in and out, which could be tuned to your own domain model.</div>

<div>As a RETE network is being created, DRL
Rules are parsed into an internal "descriptor" structure (a high
level AST)<br>
and then compiled into a RETE. <br>
<br>
There are "APIs" to create rules at the descriptor level: this can
then be "dumped" back into DRL.<br>
To work at the DRL level directly, it's common to use parametric
"templates".<br>
<br>
If your internal (meta)model is object oriented, you could
consider using DRL rules to write the translators :)<br>
<br>
Davide<br>
<br>
p.s. could you provide some more information about your use case?
I'm doing some research on rule authoring<br>
environments right now. Thanks!<div><div><br>

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

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

<br>
Is there any samples or documentation for reading and writing
of rules?<br>
<br>
The user case is we are trying to build a custom Rule Editor,
and thus would<br>
like to write and read rules to/from our beans.<br>
<br>
Thanks<br>
