The University College Dublin has launched the Irish Virtual Research Library and Archive Repository.
Here's an excerpt from the press release:
VRLA is a digital archive containing a number of digitised collections from UCD’s holdings, of use and interest to Irish humanities researchers. The IVRLA has developed a sophisticated interface enabling users to browse, search, tag and cite digital objects and view or download them in a variety of file formats. This interface sits on top of an open source repository architecture that functions as the IVRLA’s base content store. An elaborate collection model has been developed ensuring all content is viewed within context and structure. This model is particularly suited for organic primary source collections and enables hierarchy and sub-division in how objects are arranged and held within collections.
