Fedora is a robust, modular repository system for the management and dissemination of digital content. It is especially suited for digital libraries and archives, both for access and preservation. It is also used to provide specialized access to very large and complex digital collections of historic and cultural materials as well as scientific data.
Fedora's flexibility enables it to integrate gracefully with many types of enterprise and web-based systems, offering scalability (e.g., millions of objects) and durability (e.g., all of the information is maintained in files with no software dependency, from which the complete repository can be rebuilt at any time). It also provides the ability to express rich sets of relationships among digital resources and to query the repository using the semantic web's SPARQL query language.
Fedora has a worldwide installed user base that includes academic and cultural heritage organizations, universities, research institutions, university libraries, national libraries, and government agencies.
