Requirements for Standardization on the Service Registries ISO/IEC JTC1 SC /10/161 A comment to WSSG, JTC1 SC32WG2 N

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. 2015/10/162

An Idea for Taxonomy of Registry Types 4 Domain Specialty Diversity of Stakeholder Type-1 ProcessContents Type-3 Among Experts High (Narrow) Type-2 Cross Industries (BtoB) Metadata Dependent (Non Structural) Model Dependent (Structural) Low (Generic) High Target of the Standardizations System of Systems Registry Of Registries Cross Individuals Service registry 2015/10/16

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 ) : Parts Library – TC184: ISO OTD ( Open Technical Dictionary ) – TC184: ISO29002: Concept dictionaries — Resolution services 2015/10/165

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 Type-2 Registry 2015/10/166

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. 2015/10/1613
