On the first day of the event, we will begin with welcome and introductions, review the agenda, and then break into groups to work on a variety of tasks. Groups may be identified as those working on intellectual content, intellectual property, technical, etc.
The days themselves will be structured something like this. Coffee/tea will be provided. Lunch is on your own.

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 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 requires that metadata be stored in RDF. This is where the need for a PBCore RDF ontology comes in.
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 American Archive of Public Broadcasting and the Association of Moving Image Archivists (AMIA) PBCore Advisory Subcommittee.
The Schema Team is working on an updated version of PBCore (PBCore 2.1), the changes of which will consist of minor tweaks and bug fixes, and is expected to be released in March 2015. Other Teams on the Subcommittee are working on PBCore outreach, education, documentation, and a new website.
Participants should sign up for a working group. On the days of the event, these sections will be filled with suggestions and links to documentation created by the working groups.
