Framework for Metamodel Interoperability(MMF)ISO/
IEC19763(2ndCD)for discussion

• XMDR ISO/IEC/JTC1/SC32/WG2
• Joint Ad-hoc Meeting,
• UC Berkeley, Oakland, Calif.,
• 2005.01.28

2
Objectives of MMF Family of standards

• Provide a common metamodel framework to register
  various types of models and modeling constructs
  to enable them to be Sharable, Reusable and
  Exchangeable.

3
ISO/IEC 19763 Family of Standards

• Metamodel framework for Interoperability
• Project started May 2002
• Project Leader Hajime Horiuchi (JP)
• Part 1 Reference Model (JP, UK)
• Part 2 Core Model of MMF (JP, KR)
• Part 3 MMF for Ontology Registration
• 
  (Cn, JP)
• Part 4 MMF for Model Mapping (JP)

Conceivable Targets of the Registrations

• Metamodels
• Modeling Facility metamodels (e.g. UML, etc.)
• Registry metamodels (e.g. ebXML RR, UDDI, )
• Domain models
• Various business application models (UML based,
  IDEF1X based, )
• Ontology models
• Terminology
• Modeling Constructs
• Basic Information elements metadata (e.g. ebXML
  Core Components)
• Normative Codes
• Modeling Patterns
• Modeling View definitions (RM-ODP)
• Basic Terminologies

What should be Represented

• What is the identifier ?
• What is the concept of this instance model?
• What classification scheme the model is
  belonging?
• What constructs were used ?
• Who is owner?

Framework of Registering

• Sign-Concept-Instances
• 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.
• Instances
• 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.

14
Framework of Registering

• Model Sign-Model Concept-Model Instances
• Model 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 Concept
• specify meaning of the sign.
• Model Classifier of Model Concept is generally
  expressed with the sign.
• A sign is corresponding to a Model classifier
• The meaning of Model Sign is provided by Model
  Concept
• Model Instances
• a set of instance of the Concept designated by
  the sign.
• governed by Model Concept
• should satisfy the constraints concerning the
  Model Concept.
• Model Selection
• Model Selection is a result of selecting a set of
  model instances from Model Instances designated
  by a sign.
