The Data Documentation Initiative (DDI) is an effort to establish
an international criterion and methodology for the content, presentation,
transport, and preservation of "metadata" about datasets
in the social and behavioral sciences. Metadata (data about data)
constitute the information that enables the effective, efficient,
and accurate use of those datasets.

ISO/IEC 11179 Metadata Registry Implementation Coalition 
http://www.ushik.org/mrc/
The 11179 Metadata Registry Consortium is a forum for information
exchange on the implementation of metadata registries based on the
ISO/IEC-11179 Specification and Standardization of Data Element standard.
Consortium members are interested in addressing ISO/IEC-11179 reference
implementations of metadata registries, influencing commercial vendors
to support ISO/IEC-11179 in their tools, developing methods to support
metadata exchange between metadata registries, sharing information
and lessons learned on implementation approaches, being an advocate
and clearinghouse for metadata registry issues, and developing partnerships
to support data management across organizations.
