Query: The Mellon Fedora Project: Digital Library Architecture Meets XML and
  Web Services   The University of Virginia received a grant of $1,000,000 from the Andrew W.
Mellon Foundation to enable the Library, in collaboration with Cornell
University, to build a digital object repository system based on the Flexible
Extensible Digital Object and Repository Architecture (Fedora). The new system
demonstrates how distributed digital library architecture can be deployed using
web-based technologies, including XML and Web services. The new system is
designed to be a foundation upon which interoperable web-based digital
libraries can be built. Virginia and collaborating partners in the US and UK
will evaluate the system using a diverse set of digital collections. The
software will be made available to the public as an open-source release.
