Framework for Metamodel Interoperability （ MMF ） ISO/IEC ,2,3,4 （ Draft CD/WD ） for discussion ISO/IEC/JTC1/SC32/WG2 meeting Washington DC Masaharu Obayashi

Changes at 2 nd (draft) CD CD reviewed and revised based on 1 st CD comments and resolutions, also discussion with experts Change inheritance from MDR and MOF Administered Item from MDR Avoid direct inheritance from MOF Change package structure Divide normative and informative Harmonize metamodel with Ontology (part 3) and Mapping (part 4) Specification reviewed and redefined for affect of above changes

Scope This part of ISO/IEC applies to activities including: A business object is an object that is identified in building a reusable model of business or a reusable software component that should support interoperability within an enterprise or in the trade between enterprises. To identify and define a concrete object, firstly concepts in the modeling target domain must be put in order, and secondly the meaning of business objects that are picked up from those concepts should be defined exactly with the relationships among the business objects.

Scope (objectives) inter-enterprise connection –Using standardized business objects, inter-enterprise connection among customers, trading partners and business partners would be available. In addition, if a compliant model that is created based on common business objects were adopted, the interoperability among the subsystems of each section of an enterprise would be maintained in the ease way. standardization for core models –As a standard model among enterprises or in an industry, if business objects and core models were defined independent of any particular platform, the development of components and tools conforming standard functions or interoperability would be enabled. Then, the solution business by vendors would be promoted. stability and reusability of a standard model –In some cases, the lifecycle of a business application may be longer than one of hardware or platform. If a business application were built based on a business object model that was independent of any particular platform, remaking the same application on a new hardware or a particular platform would be easy and flexible by generating the code of its application from the model. Much of the maintenance cost of the lifecycle could be reduced.

Messages Developing sharable model is best promoted through accumulation of Metamodels and Ontologies Metadata about target could be also registered as a Metamodel including metaclasses and attributes Registry must be defined with separated from target MMF works to manage Granularity, Scale, and Context Using ‘Components’ to express Context Define Concepts with Components from different scales and methodologies ‘Signs’ must be separated from Concepts ‘Concepts governs Instances’ (e.g. “is-kind-of” = “governs” ) –“Employee is a kind of person” means “The model of all employees governs the model of persons” Bridging scales and context with Ontologies and Mappings Linking Ontologies to integrate or to map Metamodel and model

Framework of Registering (1) Sign-Concept-Referents Sign a symbol designating a named element in a namespace. Namespace is a collection of signs Concept specify meaning of sign. generally expressed with sign. Referents a set of instance of the Concept designated by a sign. Selection a result of selecting a set of model instance from referents designated by a sign.

Framework of Registering (2) Model Concept-Model Domain-Model Instance Model Concept (Sign) designate a named element in a namespace. Namespace is a collection of signs defined by a submitted organization Signs should be unique within the particular Namespace Model Domain (Concept) specify meaning of the sign. Model Classifier of Model Domain is generally expressed with the sign. A sign is corresponding to a Model classifier The meaning of Model Domain is provided by Model Profile Model Instances (Referents) a set of instance of the Concept designated by the sign. governed by Model Domain should satisfy the constraints concerning the Model Domain. Model Selection Model Selection is a result of selecting a set of model instances from Model Instances designated by a sign.
