MatD³ is intended to provide a simple solution for making diverse datasets available individually and rapidly. MatD³ is an open-source, dedicated database and web application framework designed to store, curate and disseminate experimental and theoretical materials data generated by individual research groups or research consortia.

A research group can set up its own instance of MatD³ and publish scientific results or simply use an existing online MatD³ instance. Disseminating research data in this form enables broader access, reproducibility, and repurposing of scientific products. MatD³ is a general purpose database that does not focus on any specific level of theory or experimental method. Instead, the focus is on storing and making accessible the data and making it straightforward to curate them.
