This catalog describes quality problems in research data focusing on material cultural objects and related data models. It has been compiled as part of the KONDA research project. This catalog aims to elicit requirements for a generic quality management process for research data through exchange with the community. The catalog is the result of qualitative interviews and a workshop with cultural heritage data experts. Within the catalog, each quality problem is described by a structured profile that includes aspects such as the quality dimensions affected, examples, causes, and ideas for improvement.
