Abstract
The quality of the metadata records in a digital library has a critical effect on its information access and retrieval. The open source Metadata Repository at the National Science Digital Library (NSDL) comprises of collections of metadata submitted from various data providers and is open for harvesting by the public. Since metadata in the repository came from many different data providers, there is a lack of consistency. This lack of consistent hampers the information services provided by the NSDL to its own web users as well as to aggregators who harvest the NSDL data. The goal of this study is to assess the quality of the current metadata records in the NSDL Repository. We harvested over one million Dublin Core metadata records submitted through November 2005 to the repository using the Open Archives Initiative Protocol (OAIP). The data harvested was loaded into an Excel database and exhaustive tabulations of all the Dublin Core metadata fields were performed. The criteria of quality assessment are based on the following areas: consistency, completeness, accuracy and local additions of data providers. This study reports on the results of the tabulations and assessment of metadata quality. Information organizations and institutions will benefit from the results of this study in determining which parts of the repository they aim to harvest. The data collected for this study will be made available to the public to contribute to promoting studies on metadata quality improvement by enabling other researchers to have access to the data for further analysis.
