The study strategy(Confirmed in the Seoul Meeting, Dec., 2007)

• The tentative goal was the preparation of a draft WD on “Model registration procedure ” to the coming Australia Meeting (May, 2008)

• Investigate and Stock take requirements on the Registrations as widely as possible.

• Implement a prototype MFI facility and investigate the registration procedure

• Propose a common procedure consolidating both procedures of MDR + MFI

3

Recommendations• Recommendation : The Registration Procedure should be standardized as a part

of MFI standard (to be the part 6) by the project sub-dividing, under the name of “The model registration procedure”.

• The part 6 should take the MDR(ISO/IEC 11179) part 6 in to the core of the standard

• Additional portions to the MDR pat 6(registration ) as the MFI 6 should cover procedures and constructs to be used for improving the interoperability among various types of models and registries

• A draft WD should be submitted to the WG2 Sydney meeting, following requirements.

4

Scope of MFI 6• MFI 6 should specify the normative registration procedure and normative

references for the domain model (ontology) registrations to the registry which is conform to MFI standards.

• MFI dose not specify any type of modeling facility and repository implementations

MFI and MDR• A model to be registered to MFI registry consists from Classes and their

relationships• Each class has attributes which are supported by metadata as data type

or value domain in MDR

Accumulation of contents is the Value of the registry. Duplication of contents may be allowed.However, to keep trust of the contents, some sort of the registration rules and metamodel should be enforced.

RO

What out of the scope are;• Harmonization process of the contents for each

domain. (To be standardized within each domain)• Change Propagation and Notification among

registries (To be discussed in ROR)

Requirements

• MFI 6 should make it clear that things to be registered and how to be used MFI metamodelsRequirement-2: (Interoperability )• MFI 6 should be considered as a core part of an infrastructure which enables the interoperability by the conceivable higher lever registries (ROR) Then, all models and ontology to be registered are required to be identified and to classified by those schema specified by MFI 6

Requirements; (Cont’d)• Requirement-3: (Procedure enforcement at implementations) Normative contents of the Part 6 should be enforced in both

human processes and machine executable processes • Requirement-4: (Self registration) The Part 6 should provide facilities for the encouragement of

registrar to complete their model registrations through the interactive processes. These facilities could enables the promoting of the accumulation of registry contents.

Requirements; • Requirement-5: (Related other MFI standards) Part-6 should be used for the registration of any kind of models

including ontology those could be acceptable for MFI-2 (core) & MFI-3 in order to promote sharing and reusing of those for the sake of interoperability among domains.

• Requirement-6: (Relation to MDR standards) The part-6 should take the MDR(ISO/IEC 11179) part-6 in to the

core of the standard

Requirement- 7: Requirements on Quality

Quality of Data

• The quality measurements and guideline of each data element or set of data elements should be domain dependent.( e.g. ISO8000)

• In MFI 6, It should be out of the scope

27

Quality of the Registration

• To maintain the Quality of the registry, the MFI 6 should specify the processes and guideline

• Those processes should be possible for software automated checking and enforcement

28

Quality of the Registry

• The Quality of Registry means that consistency and compliances to all of mandatory criteria should be kept among all of model instances in the registry

• These compliance maintenance should be responsible to the steward of the MFI registry.

29

Requirements (Con’t)Requirements-7 Identification Schema• MFI 6 should stock take major UUID providers as widely as

possible including ID schema that were used in MDR standards (e.g. IRDI)

• MFI 6 should take one of those as the recommended identification scheme

• MFI 6 should provide an own ID scheme for miscellaneous object (attached model profiles), e.g.

Note: DOI (Digital Object Identification), Ubiquitous Center (Japan),

30

Classification Schema

• MFI 6 should provide an own model classification scheme

• Those schema should consist of;– Purpose and mission– Industrial sector– Modeling View point– Domin Context

Note:UN/CEFACT TMG is discussing the Business Context Method

Requirements; (Cont’d)

• Requirement-8: (contents standardization) The MFI-6 should not to try to standardize any domain

specific contents of registries. The harmonization processes for each contents may be responsible for domain specific organizations.

• Requirement-9: (Identification & Classification ) However, the MFI-6 should provide normative bases for

referencing the identification and classification schema
