The RDA Metadata Standards Directory is an output of the Research Data Alliance Metadata Standards Directory Working Group, which operated between August 2013 and February 2015. It builds on the DCC Disciplinary Metadata Catalogue, originally compiled by Liz Bedford.
The Metadata Standards Directory Working Group was supported by individuals and organizations involved in the development, implementation, and use of metadata for scientific data. The overriding goal was to develop a collaborative, open directory of metadata standards applicable to scientific data can help address infrastructure challenges. This work is continued by the RDA Metadata Standards Catalog Working Group.
