For detailed information, a MFI registry accesses repositories that stores complete models.

MFI Part6 Registration procedure

The difference from MDR Part6Under the assumption that complete models (ontologies,

process modeles, service modes etc.) exist outside of MFI, MFI only registers a common parts of models with its administered items.

So, it is a key issue of MFI Part6 that the synchronization of a complete model and its common parts in a MFI registry.

This issue is particular to MFI Part6 and may be out of the scope of MDR Part6.

Points to be discussed (1 of 2)

Initial submissionBefore synchronization, the initial submission (and its authorization)

is necessary.The procedure of the initial submission might be almost the same as

MDR Part6.But, some new issues exist.For example, MFI Part 3 distinguishes a reference ontology and a

local ontology. So, when some organization wants to register some ontology in a MFI registry as a reference ontology as its initial submission, what is a condition of a necessary procedure?

Explicit conditions are better? such as: An ontology which is already ISO standard (e.g. ISO 18629 PSL

etc.) can be automotically a reference ontology. Or a procedural requirement is better? such as: To be registered as a reference ontology, it needs the authorization of

XXXX.

OKABE, Masao 4

Points to be discussed (2 of 3)

Synchronization There are two ways.

1. Periodical crawling by MFI After initial submission is authorized, a MFI registry periodically crawls

to the repositories that store complete models.

2. Update submission by the owners(initial submitter) Something like “When a complete model is updated, its update has to

be submitted to a MFI registry by the owner within 1 week”

For a well-authorized and frequently updated complete modeles such as Gene ontology, 1. is better. But, there may be the cases that 2. is better.

Should MFI Part6 allow both?

Points to be discussed (3 of 3)

Other issuesProcedure for the information that cannot be gained even from a

complete model? Unfortunately, there are some. Example

–Registration authority–authoritative-extent of MFI Part3 Ed2–non-functional properties of MFI Part7 ?

Change notification service To promote the registration to a MFI registry, it should provide some

services to submitters (owners). Change notification service is a minimal one. Should it be included in MFI Part6?

Future Work

Based on the discussion today, I will prepare a material for the London interim meeting in November.

Prepare CD expectedly by 2010-02-0, as stated at Resolution WG 2 / 7, in 32N1880-WG2-Resolutions-JeJuDraft-r5.
