== Summary & Background==
The PBCore RDF Ontology Hackathon is occurring out of a growing need for PBCore users to express their metadata in RDF. A number of PBCore users contribute to and are part of the [http://projecthydra.org/ Project Hydra] community, a collaborative, open source effort to build digital repository software solutions at archives institutions. Hydra is built on a framework that uses Fedora Commons as the repository for storing metadata. Many users are seeking to update their Fedora repositories to the latest version (Fedora 4), which provides a great opportunity to develop an RDF data structure. If PBCore had an RDF ontology, it would be easier for PBCore users to take full advantage of Fedora 4 capabilities in managing data and encourage adoption of Fedora 4.
<br>[http://www.pbcore.org PBCore] is a metadata schema for audiovisual materials. Its original development in 2004 was funded by the Corporation for Public Broadcasting, with a goal of creating a metadata standard for public broadcasters to share information about their video and audio assets within and among public media stations. Since its conception, PBCore has been adopted by a growing number of audiovisual archives and organizations that needed a way to describe their archival audiovisual collections. The schema has been reviewed multiple times and is currently in further development via the [http://www.americanarchive.org American Archive of Public Broadcasting] and the [http://amianet.org/ Association of Moving Image Archivists (AMIA)] PBCore Advisory Subcommittee.
