Overview of SC 32/WG 2 Standards Projects Supporting Semantics Management Open Forum 2005 on Metadata Registries 14:45 to 15:30 13 April 2005 Larry Fitzwater U.S. Environmental Protection Agency & ISO/IEC JTC 1/ SC 32/WG 2 Convener

Open Forum 2005 on Metadata Registries 2 Abstract  This presentation will give an overview of the ISO/IEC JTC 1/SC 32/WG 2 work on metadata registries, common logic, metamodel framework, and other projects. This includes work to extend the ISO/IEC metadata registry standard to handle complex concept structures. It will discuss liaisons with TC 37, OMG, W3C and other organizations.

Open Forum 2005 on Metadata Registries 3 What is Metadata?  Metadata is data about data  It’s just plain, ordinary, everyday, garden variety data  It is found in documents, messages, images, sound streams, data sets, Web sites and videos  It provides information about the data or resource

Open Forum 2005 on Metadata Registries 4 Why is Metadata Important?  Promotes clearer understanding  Helps users find information  Promotes more efficient use/reuse of information  Promotes better data management

Open Forum 2005 on Metadata Registries 5 How Does Organized Metadata Promote Better Data Management?  Provides a consistent model for capturing data about data  Captured in one place  Provides details on the custodian of the data  Links directly to online data  Reduces risk of duplicating data collections

Open Forum 2005 on Metadata Registries 6 What is the Role of a Data Registry?  Keeps facts necessary to clearly describe, inventory, analyze, and classify data  Supports data standards development process and distribution  Provides a source of well-formed data elements and value domains  Promotes the reuse of data in Agency systems and beyond  Enables data sharing, data integration, and data comparability  Serves as the central source of metadata information about Agency data
