The WIGOS Metadata Standard was developed in 2014 and endorsed by WMO Cg-15 (2015). Since then, the vocabularies for the exchange of WIGOS metadata have been continuously evolved and refined. The information model underpinning WIGOS metadata exchange has been defined based on ISO19156/OGC O&M and exchange of WIGOS metadata has been enabled by a formal specification of an XML exchange format. Recently, KPIs have been developed and implemented to assess the completeness and quality of WIGOS metadata records. As more and more communities have begun to consider the WIGOS metadata representation for use, certain deficiencies and new requirements have emerged that require an evolution of the specification. Moreover, the underlying international standard has also evolved. The WMO Task Team on WIGOS Metadata (TT-WIGOSMD) is responsible for managing both the WIGOS code lists as well as the exchange format. It closely interacts with the Task Team on WIS Metadata (TT-WISMD) in order to align as much as possible the evolution of these standards. The result of these efforts directly impacts on the evolution of OSCAR/Surface, WMO Climate Data Management System(s), GAW and GCW data management and other WIGOS-related activities.

The presentation will provide an update on the status of the WIGOS metadata information model and the specification of the WIGOS Metadata Representation (WMDR) as best practice for the documentation and exchange of observational metadata.
