About the CED²AR Project

The Comprehensive Extensible Data Documentation and Access Repository (CED²AR) is funded by the National Science Foundation (NSF), under grant #1131848 and developed by the Cornell Node of the NSF Census Research Network (NCRN). The Cornell NCRN branch includes researchers and developers from the Cornell Institute for Social and Economic Research (CISER) and the Cornell Labor Dynamics Institute. CED²AR is designed to improve the discoverability of both public and restricted data from the federal statistical system. The project is based upon leading metadata standards and ingests data from a variety of sources.
