Fedora 2.0 Open-Source DAM Solution Released The Fedora Project has announced the release of version 2.0 of its Fedora open-source digital repository software. New features include the ability to represent and query relationships among digital objects, XML encoding for Fedora digital objects, enhanced ingest and export interfaces for interoperability with other repository systems, enhanced administrative features, and improved documentation. Fedora is intended to serve as the foundation for many types of information management applications, including institutional repositories, digital libraries, records management systems, archives, and educational software.
As with prior versions of the software, all Fedora functionality is exposed through Web Service interfaces. At the core of this functionality is the Fedora object model that enables the aggregation of multiple content items into digital objects. This allows objects to have several accessible "representations." For example, a digital object can represent an electronic document in multiple formats, a digital image with its descriptive metadata, or a complex science publication containing text, data, and video. Services can be associated with digital objects, allowing dynamically-produced views, or "virtual representations" of the objects. Historical views of digital objects are preserved through a powerful content versioning system.
The new Fedora 2.0 introduces the "Resource Index" which is a module that allows a Fedora repository to be viewed as a graph of inter-related objects. Using the Resource Description Framework (RDF), relationships among objects can be declared, and queries against these relationships are supported by an RDF-based triple store. Fedora 2.0 also introduces "Fedora Object XML" (FOXML) an XML format for encoding Fedora digital objects. To support multiple XML standards, Fedora's ingest/export interface has been enhanced, permitting digital objects to be encoded in different formats. Currently, there is support for METS and FOXML. In future releases The Fedora Project plans to support other XML formats, including MPEG21-DIDL. Other new features include a mass-update utility for modifying objects, a new administrative reporting interface, improved documentation, and tutorials.
The Fedora open-source software is jointly developed by Cornell University and the University of Virginia with generous funding from the Andrew W. Mellon Foundation. Fedora 2.0 marks the final milestone in Phase I, a three year project to develop the core Fedora Repository system. Now underway, Fedora Phase II is a three year development project that will focus on advanced features including workflow, digital preservation, policy enforcement, information networks, and federated repositories.
