Quality is a multidimensional concept. The two aspects of digital library data quality are the quality of the data in the objects themselves, and the quality of the metadata associated with the objects. Maintaining usable and sustainable digital collections necessitates maintaining high quality metadata about those digital objects. The University of North Texas Libraries recognize the strategic benefit of metadata as a means of ensuring long term access to its digital resources. This paper discusses issues related to digital resources management and describes how the University of North Texas Digital Projects Unit approaches metadata quality issues at various levels of the digital resources life cycle. It also suggests a number of metadata quality assurance procedures, tools, and associated quality assurance mechanisms.
