The basic goal in designing Credo is to provide simple and intuitive access to digital collections within a repository architecture that is both robust and flexible and that adheres to open standards. The flexibility of the underlying Fedora Commons Repository software (maintained by the DuraSpace Organization) allows us to continue to develop Credo and to add additional features as we explore the best ways to deliver digital content to the public.

To provide richly detailed descriptions and finely-tuned discovery tools, we used the Metadata Object Description Schema (MODS) to describe all objects in Credo. SCUA has developed an extensive set of best practices detailing our implementation of MODS for the description of manuscripts at the item-level.

Although Credo is not a digital preservation system, we have made sure to use open, platformindependent standards and have maintained detailed information about our digital objects, which we have structured in metadata and outlined in external documentation. As the UMass Amherst Libraries develop a full digital preservation infrastructure, we are confident the digital collections in Credo will be available far into the future.
