QDR selects, ingests, curates, archives, manages, durably preserves, and provides access to digital data used in qualitative and multi-method social inquiry. The repository develops and publicizes common standards and methodologically informed practices for these activities, as well as for the reusing and citing of qualitative data. Four beliefs underpin the repository’s mission: data that can be shared and reused should be; evidence-based claims should be made transparently; teaching is enriched by the use of well-documented data; and rigorous social science requires common understandings of its research methods.
