Make sure to provide rich metadata not only about your study, but also about the study resources or documents used (e.g., study protocols, sample data entry forms, sample patient information and consent forms, codebooks, questionnaires, data dictionaries).
In addition to the publication of study metadata, the German Central Health Study Hub allows researchers to individually publish additional study documents, link them to the study metadata, and provide information on access regulations (learn more) as well as information on the derived research data.
For machine-readable questionnaires and data dictionaries in particular, the German Central Health Study Hub provides specific overviews, filters, and searches (learn more).
