Slide3Introduction to Discovery Level Metadata
A data set description (metadata) that provides information to determine if a particular data set meets the users’ needs.Typically provides essential information to enable a user to find out if a particular dataset exists, the data’s location, and ownership, and how to obtain further information.The metadata includes the science discipline of the data, data location, spatial coverage, data provider, data resolution, data quality, etc. Discovery level metadata is found in “portals” and metadata registries.A controlled keyword vocabulary helps provide a consistent search and discovery of data.

Slide6Relevance to Data Management Discovery level metadata makes it easier to find relevant data in portals, metadata registries, and data inventory systems.
Being able to find and distinguish data from other similar data sets makes maintaining a data inventory easier because data managers have a better understanding of the content in their system.Creating and maintaining metadata is part of a data management lifecycle.
