The Semantics of Business Vocabulary and Business Rules (SBVR), v1.0 document (Object Management Group 2008) is an Available Specification, published by the Object Management Group (OMG), that defines the vocabulary and rules for documenting the semantics of business vocabulary, business facts and business rules. The specification is applicable to the domain of business vocabularies and business rules of all kinds of business activities of all kinds of organizations. It is conceptualized optimally for business people rather than automated rules processing, and is designed to be used for business purposes, independent of information system designs. This report describes two metamodels as instances of MOF: the first one is the subset of the SBVR metamodel necessary for describing conceptual schemas as a combination of concepts and facts as defined in SBVR. The second one describes the subset of the SBVR metamodel concerning representations of the meanings.
