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.
