The level of service that metadata-based systems could provide is directly influenced by the metadata characteristics. Several of these characteristics are encompassed under the concept of “quality”. As important as it is for these systems, metadata quality is a poorly researched area due to its inherent complexness and subjectiveness. This section presents the main theoretical approaches to the definition of metadata quality and its multiple dimensions. It also presents and compares the most followed frameworks to estimate the quality of metadata records. To provide a real perception of the current status of metadata quality, this section also describe several manual and automated studies in real digital repositories. Full examples of how these studies are conducted are also provided. Finally, the section presents a selection of strategies and tools to evaluate the quality of metadata. The section closes with conclusions about the current state of research on metadata quality and perspectives for the future.
