"The National Science Foundation (NSF), through its Division of Undergraduate Education, is funding the development of the National Science Digital Library (NSDL) over the next 5 years. A limited public release of the NSDL was launched on December 3, 2002. NSF expects the NSDL to become, over-time, the world's largest digital library of STEM (science, technology, engineering and mathematics) information resources and services as well as an online network of learning environments and resources for science, technology, engineering, and mathematics education at all levels.
Many of the resources that populate the NSDL collection will come from projects funded under the NSDL program and related NSF digital library initiatives. However, the goal is to include access to as many relevant STEM resources as possible, including both open access and proprietary materials.
The Core Integration (CI) team of the NSDL is distributed among a group of collaborating institutions (University Corporation for Atmospheric Research (UCAR), Cornell University, Columbia University, the San Diego Supercomputer Center, the University of California at Santa Barbara, and the University of Massachusetts at Amherst) and is aimed at the development, deployment, and support of both the technical and organizational infrastructure of the NSDL. The Cornell team is lead by a group of computer scientists and librarians.
A core component of CI responsibility is the development and maintenance of a metadata repository comprised of collection and item level metadata which serves as the basis for search and discovery services. The metadata repository will be built using a combination of methods including metadata ingest by the Open Archives Metadata Harvesting Protocol OAI-MHP. The NSDL metadata repository is built on open source, open access principles and standards and thus will also be available for harvesting by other services. While the principle of open access and free search and discovery services is a fundamental principle of the NSDL, the NSDL is concurrently looking at integrating proprietary content into it's distributed collections. Authentication and authorization services are being developed to allow for user access to fee-based content once it has been discovered within the open (i.e.free) search/browse services built on the OAI compliant NSDL metadata repository.
