The Meta Object Facility (MOF) is an OMG metamodeling and metadata repository standard. It is an extensible model driven integration framework for defining, manipulating and integrating metadata and data in a platform independent manner. MOF-based standards are in use for integrating tools, applications and data [1].

Key Points

MOF was developed as a response to a request for proposal (RFP), issued by the OMG Analysis and Design Task Force, for Metadata repository facility (http://www.omg.org/cgi-bin/doc?cf/96-05-02). The purpose of the facility was to support the creation, manipulation, and interchange of meta models.

MOF provides a metadata management framework, and a set of metadata services to enable the development and interoperability of model and metadata driven systems. The MOF metadata framework is typically depicted as a four-layer architecture as shown in Table 1:
