The University of Maryland Libraries has launched its Digital Collections repository.
Here's an excerpt from the announcement:
This release marks two and a half years of work in the creation of a repository that serves the teaching and research mission of the University of Maryland Libraries. Many of the objects are digital versions from Maryland's Special Collections (such as A Treasury of World's Fairs Art and Architecture) or are new virtual collections (The Jim Henson Works). Other collections (such as Films@UM) support the teaching mission of the Libraries. This release also marks the integration of electronically available finding aids, ArchivesUM, into the repository architecture, creating a framework for digital objects to be dynamically discovered from finding aids.
The repository is based on the Fedora platform, uses Lucene for indexing, and Helix for streaming video. The repository features almost 2500 digital objects, with new objects added monthly. Object types currently delivered include full text (both TEI and EAD), video, and images. Objects can be discovered within a collection context or via a search across multiple collections. Cross-collection discovery is achieved through a common metadata scheme and controlled vocabulary. This metadata scheme also provides for individual collections to have more granular domain-specific metadata.
An FAQ for the repository is available.
