Leveraging National Federated Identity Services
Stuart Kenny, Peter Tiernan
Trinity College Dublin, Ireland
 

The Digital Repository of Ireland (DRI) is an interactive, trusted digital repository for social and cultural content held by Irish institutions. By providing a central internet access point and interactive multimedia tools, the DRI will facilitate engagement with contemporary and historical data, allowing the public, students, and scholars to research Ireland’s cultural heritage and social life in ways never before possible.

As a national infrastructure DRI must be accessible to a broad range of user, from cross-institutional research teams, to casual users from the general public. To reduce the administrative burden on the repository it would be highly desirable if accounts could be dynamically provisioned, rather than requiring the intervention of an administrator. Similarly removing the ongoing maintenance of accounts would aid in the long-term sustainability of the infrastructure.

For these reasons DRI has leveraged an existing national federated access management system, Edugate. Through this service users can access any Edugate enabled online resource using the credentials issued to them by their home institution.

The integration of this service has opened DRI to a large number of potential users, without the expected increase in administrative overhead.

Analyses of the usefulness of Software Defined Storage Solutions for Web-based Digital Preservation Applications

Peter Tiernan, Jimmy Tang, Kristina Bako
Trinity College Dublin, Ireland
 

The Digital Repository of Ireland (DRI) is an interactive, national trusted digital repository for contemporary and historical, social and cultural data held by Irish institutions. The DRI has a requirement for a massively scalable, fully featured storage solution to store and preserve digital assets. Software defined storage has brought large scale storage within the reach of ordinary engineers and developers. The power and features provided by such systems can prove revolutionary and has the potential to deliver stable, vastly scalable storage to repository infrastructures at low cost. This presentation will explore four such solutions: Ceph, iRODS, GPFS and HDFS. Their features will be analysed and tested to assess suitability for the DRI. Criteria useful to digital repositories such as High Availability, Interfaces and Interoperability, replication and data security will be used to determine which solution best fits.
