Study Report on ROR (Registry Of Registries)

1. SC32WG2 N 1263 Study Report onROR(Registry Of Registries) 2009.6.23 Hajime Horiuchi MFI Project Leader

2. Scope Specify a standard registry to enable users to discover other registries and the services they provide. This standard provides an infrastructure to enable the interoperability among registries that were constructed according to different registry standards or domain specific requirements. This standard specifies metamodels that describe registries and their services

3. Original Schedule • Study report 1: 2008.11 (Portuge) • Study report 2: 2009.06 (Jeju) • WD: 2009.06 (Project split: MFF-9? ) • CD: 2009.XX should be extended

4. Agreement • We desire to share common facilities such as Administered Item, Designation and Identification between MDR and MFI standards. • Those should be investigated at the CD2 stage for 11179-3 (edition 3) • MFI standards should take those changes into account at the appropriate stage for each part.

5. SC32 perspectives to the registry Standardization • SC32 recognize that there are so many different registry or metadata standard activities in both ISO or outside of ISO. • To clarify requirements to the Service Registry standards, A taxonomy of registry type should be investigated in the discussion of the those standardizations.

7. An Idea for Taxonomy of Registry Types Target of the Standardizations Process Contents High (Narrow) Type-1 System of Systems Model Dependent (Structural) Among Experts Domain Specialty Registry Of Registries Type-2 Cross Industries (BtoB) Metadata Dependent (Non Structural) Service registry Type-3 Low (Generic) Cross Individuals Diversity of Stakeholder High 102 108

8. Type-1 Registry • Dedicated Registries for specialized closed domains such as Space & Air, Defense, Automobile or Medical industries to support high skilled engineer/experts like SOSE (System of Systems Engineering) • Sharing models and process by domain experts. • Registry User: limited experts. • Example: • TC184: ISO13584 (IEC 60130 ) : Parts Library • TC184: ISO 22745 OTD ( Open Technical Dictionary ) • TC184: ISO29002: Concept dictionaries — Resolution services

9. Type-2 Registry • Registries to support cross industries B to B business information sharing in the e-business such as the Supply Chain or Traceability. • ebXML RIM & RS is a typical standard in this type. • But, different registry standards or non standardized registries were implemented in each industry domains (Heterogeneous Registries) • Registry User: various different business domain experts • ROR (Registry of Registries)standard might be needed

11. Type-3 Registry • Registry for discovery of services and orchestration of services. • the UDDI is typical registry in this type. • Registry User: Unlimited • Problems: • Who should be responsible in the contents maintenance • How to segregate from Google or Yahoo

12. Comparison of Registry Types

13. Summary of comparison • Risk at Type-2 & Type-3 • Concentration of Maintenance efforts • Concentration of RA(Registration Authority） • Difficulty on the tracking changes or versions • Difficulty on assurance of ID or URI persistency • Small returns on the registration efforts at users • How to differentiate from Google or Yahoo Needs for standards of registry content definitions that enable Automatic Syndication without any central maintenances.

15. Recommendations for WSSG • The Service Registry should be considered as a type of the registries • It should be investigated that Registry Standards for type-2 still needed to ensure the integrity and the security in Business domains (BtoB) or not. • To promote standardization by the PAS procedure at this area, it is needed to organize and coordinate SDOs in both ISO & Industrial consortia more widely. • SC32 initiated study projects on ROR and Metamodel for Service Definition, then,SC32 appreciates to share study results with the WSSG.

Problems • Risk at the CentralizedRegistry • Concentration of Maintenance efforts • Concentration of RA(Registration Authority） • Difficulty on the tracking changes or versions • Difficulty on assurance of ID or URI persistency • Small returns on the registration efforts at users • How to differentiate from Google or Yahoo • Who should be responsible to the dependability of registries 12th Open Forum for Metadata Registry, Seoul, Korea
