This document discusses measuring the quality of cultural heritage metadata. It proposes a generic "Metadata Quality Assurance Framework" tool to measure metadata quality across different schemas. The tool would measure completeness, availability, and other dimensions using structural analysis and by mapping metadata elements to discovery functions. It would provide customizable and scalable quality reports to help data curators improve metadata. The document outlines technical requirements and modules for an open source tool to systematically measure metadata at the record and aggregate level.
