Abstract

In this paper, we present a new framework complete with implementation, for a digital repository that will address some of the most difficult issues facing repository managers today: how to enable federated identity access, rapidly changing access control requirements, and the management of multiple metadata standards for different types of digital objects.

Our work draws together leading industry standards in the area of authentication, authorization, and metadata management, and apply them in a new and innovative way to the repository landscape. As a demonstration, we apply our work to a speech annotation research project which makes use of a repository to manage its culturally sensitive data.
