Welcome to the Global Digital Format Registry!

The GDFR is meant to be a distributed and replicated registry of format information
populated and vetted by experts and enthusiasts world-wide.

Formation of the Unified Digital Formats Registry (UDFR)

In April 2009 the GDFR initiative joined forces with the UK National Archives' PRONOM registry initiative under a new name - the Unified Digital Formats Registry (UDFR). The UDFR will support the requirements and use cases compiled for GDFR and will be seeded with PRONOM's software and formats database.

For more information about the UDFR, plase see the UDFR website.
