April Registries F Using this term loosely, there are several types of registries in the area of data management and interchange. F The registries have some common, overlapping content, which is extended and utilized in different ways. F The registries vary according to the intended purpose, granularity of contents, the level of semantics management.

April Theme: Semantic Interoperability between Registries F Users will have to work with several of these registries simultaneously, since the registries perform different functions. F There is a need for the registries to interoperate, since they contain related and sometimes overlapping information. The data must be kept updated and synchronized with a minimum of effort.

April In Brief: F Organize a major conference drawing together standards developers, software developers and practitioners. The major topic will be semantic interoperability between registries. F ISO/IEC is primarily aimed at semantics management and will be the focus of the practitioner tracks, with implementations in the above named areas. Special emphasis will be given to interoperation between registries, UDDI registries, XML registries/repositories, database catalogs, etc. F The conference organizers will work with standards developers, software developers and practitioners to encourage progress toward interoperability. The conference is intended to showcase progress made. F The conference is expected to have separate tracks for various communities of interest. F We expect that presenters will be invited, rather than sending out a call for papers. F The conference is expected to have multiple sponsors/hosts, with ISO/IEC JTC 1 SC32 (Data Management and Interchange) /WG 2 (Metadata) as the initial sponsor and EPA/GSA/HHS the initial hosts.
