Implementing PREMIS RDF in the Fedora4 Linked Data Platform
1North Carolina State University Libraries; 2University of North Carolina at Chapel Hill
As part of the migration from Fedora 3 to Fedora 4, the repository team at the University of North Carolina at Chapel Hill has undertaken to migrate the encoding of its preservation and rights metadata as well. This presentation will discuss the motivations behind moving from XML PREMIS logs to storing PREMIS as RDF and challenges behind implementing this. We will discuss the data model for PREMIS events in RDF and make the case for repositories wanting to move towards an RDF based approach for PREMIS event logs in Fedora 4. It will also discuss findings related to performance and usability implications of the approaches investigated.

Applying Repository Systems to Audiovisual Preservation
1Indiana University, United States of America; 2WGBH Educational Foundation, United States of America
Managing the preservation and access of digital audio-visual files continues to be a complicated challenge. The size of the files, the variety in file formats, and the sheer volume of files complicates workflows, and system processing. This presentation will discuss the HydraDAM project, a partnership between WGBH and Indiana University. We will discuss workflows undertaken at a broadcast station archive and at a university using a Hydra and Fedora system implementation to manage the influx of media preservation files.
Due to their size, files are stored outside of the Fedora repository proper, but technical and preservation metadata, including PREMIS data, is managed directly within Fedora 4. The design and implementation of HydraDAM2 to manage PREMIS events will be reviewed, along with the project’s experience in integrating external high-capacity asynchronous storage and connecting HydraDAM2 to workflows and systems for access. We will also touch on the idea of using Fedora to also store legal and rights metadata for media materials.
