MetaData for Geodata

Endorsed Specification
Description
 

The CGDI supports peer registries that contain metadata about geodata resources. These registries identify the agencies that are responsible each attribute dataset, and descriptions of that attribute data. They also contain information on how to access the data.

The content of the registry is defined by the U.S. Federal Geographic Data Committee's "Content Standard for Digital Geospatial Metadata".

Other Info
 

A new North-American Geospatial Metadata Profile for ISO 19115 has recently been developed. This profile will become an alternative to the current CSDGM profile.

Geodata Resource Registries will need to be used to store information about geolinked data resources. CSDGM is not appropriate for the metadata required for geolinked data for two reasons.

  1. A large portion of the metadata associated with the Geographic Data Discovery Service is irrelevant for users of geolinked data.
  2. Important metadata required for geolinked data is missing from CSDGM, such as the names of the linkage fields in both datasets.
