Lisa ----- The ever-increasing applicability of digital content in all aspects of research, learning, commerce, and entertainment is paralleled by the need for effective solutions to ensure the long-term preservation and use of that content. Properly managing information about the digital formats used to represent content lies at the heart of preservation activities. The Unified Digital Format Registry project (UDFR, http://www.udfr.org/) is developing a reliable, sustainable, and publicly available semantic knowledge base of file format representation information for use by the international digital curation, preservation, and repository communities. Oversight for the project rests with a group of stakeholders drawn from academic and national libraries and archives around the world, including the University of California, Harvard University, the Florida Center for Library Automation, the Library of Congress, Library and Archives Canada, the British Library, the UK and US National Archives, the Koniklijke Bibliotheek and Nationaal Archief of the Netherlands, and many others. The project is funded by the Library of Congress as part of its National Digital Information Infrastructure Preservation Program. The incumbent will be responsible for implementing the UDFR system, and is expected to provide innovative thinking and technical expertise while drawing on the body of useful experience from the PRONOM and GDFR projects and the UDFR consortium. The developer will consult regularly with UC3 staff and will work under the supervision of the project architect. The final open source system must be flexible, scalable, reliable, sustainable, and consistent with best practices and advances in web-based information services, service-oriented architectures, information preservation, and semantic web and linked data technologies. The UC Curation Center (UC3) at the California Digital Library (CDL) is one of the world's premier digital curation programs. UC3 is a creative partnership of the CDL, the ten campuses of the University of California, and the international curation community, providing innovative services and solutions to ensure the long-term usability of the University's valuable digital content.
