Metadata – Data With a Purpose
• What is Metadata?– Data about data– Descriptive information
that characterizes a set of quantitative and/or qualitative measurements and distinguishes that set from other similar measurement sets. - (L. Olsen)

Global Change Master Directory (GCMD)
MissionAssist the scientific community in the discovery of Earth science data, related services, and ancillary information, which includes descriptions of platforms and instruments.Our responsibility is to provide discovery-level metadata of Earth science resources and provide scientists a comprehensive and high quality database to reduce overall expenditures for scientific data collection and dissemination.

Discovery Level Metadata
7
•The GCMD hosts discovery level metadata describing data set collections and subsets through the CEOS IDN Directory Interchange Format (DIF).
•Information (keywords) that can be used to identify and locate the data that meet the user's requirements (via a Web browser, a Web based catalogue, etc). - British Atmospheric Data Centre

Portals: Virtual subsets of the directory, allowing organizations to maintain and document their contributed data set and service descriptions.
Portals may provide a targeted science or application-specific focus for agencies, science focus groups, consortia, etc.
