Implementing PREMIS RDF in the Fedora4 Linked Data Platform

Sonoe Nakasone1, Benjamin Pennell2

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.


9:30am - 10:00am

Fedora Repository lessons learned at ICPSR

Harshakumar Ummerpillai, Thomas Murphy, Matthew Richardson

ICPSR, United States of America

ICPSR have been developing a new digital assets management system based upon the new architecture called Archonnex@ICPSR. Fedora V4.x is one of the core components in the technology stack. This presentation aims to share the lessons we learned over the past 18 months building the new OpenICPSR system which allows self-publication of data by social science researchers. We will demo some of the key features developed to administer Fedora system. Also it might be of interest to communities trying to build a new GUI for Fedora. We developed a JavaScript based UI for Fedora administration, a custom flavored data encryption for security and customized export/import utility with version support. Some of the key features of Fedora (easy to use ReST API) that we have used are versioning, fixity, and transaction support. Some of the challenges were lack of SPARQL query support and some software code bugs that is hindering versioning and ability to sync data more effortlessly with UI.


10:00am - 10:30am

Applying Repository Systems to Audiovisual Preservation

Jon W. Dunn1, Karen Cariani2

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.
