1.1 Inclusions This is a part of the ISO/IEC19763 (Metamodel framework for interoperability) (MFI) family of standards. As the first part of MFI, this part provides an overview of the whole of MFI. In particular, the purpose, the underlying concepts, the overall architecture and the requirements for the development of other standards within the MFI family are described. MFI provides a set of normative metamodels to enable the registration of many different types of model. Each of these metamodels is expressed as a UML Class Diagram. MFI is evolving. Currently, in addition to this part, the MFI family comprises: A core model and facilities for the basic mapping of models (Part10) A metamodel for ontology registration (Part3) A metamodel for process model registration (Part5) A metamodel for service model registration (Part7) A metamodel for role and goal model registration (Part8) A Technical Report describing on demand model selection based on RGPS (Role, Goal, Process and Service) (Part9) A metamodel for information model registration (Part12) A metamodel for form design registration (Part13) A metamodel for a registry summary (Part6) These parts are described in more detail in AnnexA. 1.2 Exclusions The MFI does not specify any physical structure of the registry where model information is to be recorded. MFI metamodels define standard views as models to be used in the registering of model instances in a model registry while actual instance documents could be stored in a model repository.
