FGDC/CSDGM - Federal Geographic Data Committee Content Standard for Digital Geospatial Metadata

BGDC policy states that non-Federally authored standards that are endorsed by the FGDC have the same status as FGDC developed standards. Since ISO 19115 and the associated standards are endorsed by the FGDC, federal agencies are encouraged to transition to ISO metadata as their agencies are able to do so.
