PRR — Replace references to metamodel to metamodel and profile

  • Key: PRR-2
  • Legacy Issue Number: 13539
  • Status: closed  
  • Source: Knowledge Partners, Inc. ( Paul Vincent)
  • Summary:

    Replace references to metamodel to metamodel and profile. Chapter should now read: The following MOF2 compliant metamodel and profile defines the PRR. They feature: • A definition of production rules for forward chaining inference and procedural processing. • A non-normative definition for an interchangeable expression language (PRR OCL) for rule condition and action expressions, so they can be replaced by alternative representations for vendor-specific usage or in other standards. • A definition of rulesets as collections of rules with a particular mode of execution (sequential or inferencing). The metamodel and profile are composed of: • a core structure referred to as PRR Core • an non-normative abstract OCL-based syntax for PRR expressions, defined as an extended PRR Core metamodel referred to as PRR OCL. Future extensions of PRR may address: • rule metamodels and profiles for other classes of rules, such as Event-Condition-Action (ECA), backward chaining, and constraints • rule representations that are specific to graphical notations, such as decision tables and decision trees • representations of sequences of rulesets within larger decisions • transformations between PRR and other MDA models such as SBVR.
