Metadata quality study for the national science digital library (NSDL) metadata repository

Metadata repositories are loosely-controlled environments where each discrete metadata dataset retains its independent identity, multiple standards were applied, and records were contributed on a voluntary-based system. As more integrated digital libraries take such an approach in order to provide comprehensive collections, quality of the metadata records describing these collections items has drawn increased attention, since they function as a ‘window of a digital library collection and its services and directly involve in the success or failure of any information seeing performance. This poster reports the preliminary findings from a project funded by the National Science Foundation to study the quality of the metadata records in the National Science Digital Library (NSDL)s Metadata Repository.

Providing parallel metadata for digital libraries with linguistically heterogeneous documents

Discusses multilingual and culture-dependent metadata issues affecting the GREEN digital library and proposes a robust approach to internationalizing digital library collections.

The NSF NSDL GREEN Digital Library: Green's Functions Research And Education Enhancement Network

Greens functions are powerful mathematical tools with strong pedagogical value providing not only solutions to difficult problems but also visualization for understanding phenomena. The majority of upper division engineering and materials science students receive very little exposure to Greens functions and the boundary element method. The G reens Functions R esearch and E ducation E nhancement N etwork (GREEN) Digital Library which the authors are developing will, therefore, play an important role in undergraduate and graduate education. The National Science Foundation has launched the National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL) program to stimulate and sustain continual improvements in the quality of science, mathematics, engineering, and technology education. The NSDL Program is a major digital library initiative and the GREEN Digital Library is a collaboration of the Center for Theoretical and Computational Materials Science of the Materials Science and Engineering Laboratory at the National Institute of Standards and Technology, Kent State University, and the Massachusetts Institute of Technology. This paper describes the primary components of the GREEN Digital Library, an organized collection of educational materials integrating research, education, and application of Greens functions to serve undergraduate and graduate communities: 1. Problem Bank: A bank of available “real-world” problems, introduced by industrial participants. 2. Code Bank: Working code for solved Greens functions routines. 3. Archive: A list of citations to relevant literature, and published / unpublished works subject to copyright restrictions, with links elsewhere for additional information. 4. Teaching Bank: A collection of lecture / course notes from existing university courses, as well as providing a forum for discussion of approaches to teaching this material.
