The Production Rule Representation (PRR) is a proposed standard of the Object Management Group (OMG) to provide a vendor-neutral rule-model representation in UML for production rules as used in forward-chaining rule engines.
The OMG set up a Business Rules Working Group in 2002 as the first standards body to recognize the importance of the "Business Rules Approach".
It issued 2 main RFPs in 2003 – a standard for modeling production rules (PRR), and a standard for modeling business rules as business documentation (BSBR, now SBVR).
PRR was mostly defined by and for vendors of Business Rule Engines (BREs) (sometimes termed Business Rules Engine(s), like in Wikipedia).
