Abstract

• This presentation describes efforts underway to
  increase the capabilities of metadata registries
  which will result in a new Edition (E3) of
  ISO/IEC 11179 family of standards. Major
  advancements include semantics management
  capabilities.

What is Metadata?

• Metadata is data about data
• Its 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
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
