David,

   For 5.2 we are introducing a high level API for rule authoring. Documentation is not ready yet, but you can see the API here:

https://github.com/droolsjbpm/drools/tree/master/drools-compiler/src/main/java/org/drools/lang/api

   DescrFactory is your entry point.

   Before 5.2, the options are to generate DRL string using templates or build the *Descr AST manually. Please note that the *Descr classes are internal and might change from version to version.

Hi,

Can someone point me in the direction of documentation or code examples for the following? I want to programatically create rules for execution, e.g. within my application I will hold criteria which users will define, at runtime I would like to build a component to extract these values (from my app database) and build rules based on those values. Everything I've seen so far seems to talk about using DRL files, ideally I want to programatically create the entire rule in Java, and then call Drools to execute my rule set.

Thanks,
