WMO Core Metadata Standard

This is a draft metadata standard for the WMO and is a core profile to ISO 19115. The expert team's documents reference a controlled vocabulary, but also emphasize the need to build ontologies.

This core provides a general definition for directory searches and exchange that should be applicable to a wide variety of WMO datasets at the discovery level. Like the fundamental standard ISO 19115, the WMO Core Metadata Standard does neither specify how these metadata should be archived or presented to users nor does specify any particular implementation (this is currently underway with the development of ISO 19139.

The IOOS DMAC is coordinating with this effort.
