The University of California Curation Center (UC3) is pleased to announce the availability of the Unified Digital Format Registry (UDFR).  http://udfr.org/

The goal of the UDFR project is to "unify" the function and data holdings of PRONOM and GDFR into a new semantically-enabled, community-supported, open source registry of format representation information.  The initial UDFR data were imported from the IANA MIME type registry and PRONOM, and include information about:

*         846 file formats

*         28 character encodings

*         17 compression algorithms

*         1,198 MIME types

*         548 external signatures (file extensions)

*         494 internal signatures (magic numbers)

*         268 software packages

*         156 agents

The UDFR is based on the OntoWiki semantic wiki platform and the Virtuoso RDF quadstore.  A user's guide to the UDFR, including an introductory "Getting Started" section, is available at http://udfr.org/docs.  Use of the UDFR is open to the public, although contribution of new, or editing of existing, data requires prior self-service account registration.

Development of the UDFR was generously supported by the Library of Congress as part of its National Digital Information Infrastructure Preservation Program (NDIIPP).  More information about the UDFR project is available at http://udfr.org/project.  A mailing list, [log in to unmask]<mailto:[log in to unmask]>, is available for comments and discussion.  To subscribe, follow the instructions at http://udfr.org/docs.
