1. Metadata Catalogue and Knowledge Network
ICSU-WDS Members’ Forum

2. Working Group Charter: Background
The ICSU-WDS Scientific Committee identified at its 7th meeting (1-2 November 2012), the need to update the concept of the WDS Data Portal and build an online open WDS Metadata Catalogue that can be used to discover and access the quality-assessed scientific data and information holdings of WDS Regular and Network members.
The WDS-SC also subsequently identified the need to test the feasibility of developing a scalable and agile WDS Knowledge Network, which draws information from the WDS Metadata Catalogue but which is heavily supplemented with additional data and information from a variety of other sources.

6. Example: GEO BON Guidance
General guidelines in respect of data management
Specific guidelines to foster semantic interoperability
Data shared in global repositories that serve a specific data family and is well established.
Remaining data published and catalogued using widely adopted interoperable service standards and content schema
Community should play a role in extending such service standards and content schema where deficiencies exist.
