  1. 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

  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 11179 metadata registry standard to handle complex concept structures. It will discuss liaisons with TC 37, OMG, W3C and other organizations.

  3. What is Metadata? • Metadata is data about data • It’s just plain, ordinary, everyday, gardenvariety data • It is found in documents, messages, images, sound streams, data sets, Web sites and videos • It provides information about the data or resource

  4. Why is Metadata Important? • Promotes clearer understanding • Helps users find information • Promotes more efficient use/reuse of information • Promotes better data management

  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

  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
