NCore: Architecture and Implementation of a Fedora-based Digital Library

Ihtaca, NY A paper by Dean B. Krafft, Aaron Birkland, and Ellen J. Cramer that provides details about NCore—an open source architecture and software platform for creating flexible, collaborative digital libraries—is now available. This paper will be presented at the Joint Conference on Digital Libraries (JCDL) 2008 in Pittsburgh, PA.
NCore was developed by the National Science Digital Library (NSDL)NSDL Annotation project, and serves as the central technical infrastructure for NSDL. NCore consists of a central Fedora-based digital repository, a specific data model, an API, and a set of backend services and frontend tools that create a new model for collaborative, contributory digital libraries. This paper describes NCore, presents and analyzes its architecture, tools and services; reports on the experience of NSDL in building and operating a major digital library with NCore during the past year; and the experience of the Digital Library for Earth Systems Education in porting their existing digital library and tools to the NCore platform.
