Objectives of MMF Family of standards

• Provide common metamodel frameworks to register
  various types of
• metamodels
• models (Ontologies)
• modeling constructs
• to enable them to be
• Sharable
• Reusable
• Interchangeable

Conceivable Targets to be Registered

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

19763 part-2 Core Model

• Currently 2nd CD

23
19763-2 Core Model

• Provide base for registering models and
  metamodels, Keeping relationship among them and
  pre-registered various model constructs
• Provide selection mechanism of models with its
  whole structure or a part of the model
• (Zoom IN/ Zoom Out)
• Provide selection mechanism of a model or
  metamodel with appropriate description of concept

24
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.

Proof of Concept

• SC32WG2 ebXML Asia Committee

43
Proof of Concept

• The Project is supported by METI, as an
  International Joint Standards Development
  Project, since 2003.
• POC
• The National Registry Repository for
  E-Commerce , Project, in ECOM Japan, 2003-2007.
• SC32WG2 ebXML Asia Committee Joint Ad-hoc
  Working group for Registry and Repository
  Federation, 2004. (Jp, Kr, Cn, Sp, My, Tw, HK,
  )
• The Registry Development project (LCDM ) for the
  Construction Industry in Japan, Jan., 2005

44
Registry Repository Federation Project

• Initiated at SC32 Xian Meeting, April 2004.
• ebXML Asia Committee SC32WG2
• Implement actual registry federation using
  ISO/IEC11179 (MDR) and ebXML RR
• POC for ISO/IEC19763(MMF)
• Members
• Japan, Korea, China, Hong Kong, Taiwan, Singapore

45
RR Federation Joint Adhoc SWGwith SC32WG2 and
ebXML Asia
Objective Through the Proof of Concept for RR
Federation Model based on the international
standards, 1. Verify the standard of MDR and
MMF. 2. Promote the implementation of RR
Federation service.
46
Proposal
Collaboration Role SC32WG2 and ebXML Asia
SC32WG2 Develop federation models based MMF
and MDR ebXML Asia Focus on the implementation
of the Federation BTW the Registries

Detailed Tasks

• Harmonization of Core Components
• Harmonization BIE then extract ACC BCC
• Provide common descriptions
• Semantic Mapping
• Implement ebXML RR
• Administrative Task for the federation
• Define Federation Scope and Policy
• Develop XML Scheme for Scope and Policy
• Register each RR metamodels with MMF for the
  federation
