Hi,
The OMG Production Rule Represation (PRR) aims to standardize a business rule formalism independently of any rule engine. The OMG PRR is at the Platform Independent Level (PIM) of the Model Driven Architecture (MDA) will offer a MOF instance of a rule formalism (UML). The OMG has requested a proposal until 2003 and at this moment no real submission exist. As related work, the Rule Interchange Format (RIF) exist at the W3C. The W3C work on rule formalsm is planed in 2 phases. The first phase will be terminated in November 2007. Before OMG PRR and W3C RIF other tentatives have existed like RuleML, Common Rules (IBM) Simple Rule (ILOG). Actually it does not exist any standard rule formalism in UML and this make late the adoption of business rule approach because you have note a flexible way to migrate your rules into another rule engine format (loke JRules to JBoss Rules or JBoss Rules to Jess and so one). In a project what we have done is to create our one rule formalism in UML and uses models transformation to transforme our rules to the selected rule engine.

You have OMG PRR, but I don't know much about that.
