Master data directories and Catalog Interoperability

While the 'Catalog Interoperability' (CI) project began as a NASA effort to facilitate identification, location, and access to data of interest to space and earth sciences researchers, it now has a membership encompassing numerous U.S. and international agencies as well as academic institutions. CI is creating a global network of interconnected directory, catalog, and inventory systems. Its directories contain brief summary information about data sets, and can either furnish automated links to other information systems yielding greater detail on matters of interest or indicate to whom requests for additional information can go.
