For DOACH, Diamond OA Journals are quality-assured scholarly journals that meet the DIAMAS definition.

Diamond Open Access journals are owned by the scientific community. Scholars have full control over the publishing process, from author rights to editorial workflows.

Researchers can access and publish scholarly content without any fees regardless of their affiliation and geographic location.

Diamond OA enables publications in a diversity of languages, formats and subjects that meet the needs of researchers and are tailored to the output of their research. This is important not only for journals but also for long-form publications.

Diamond OA journals are predominantly run within academic institutions and societies that are not profit-oriented. These prioritise journal quality over commercial considerations. The financing of Diamond OA books is still in flux; there are promising models of community-funding such as the Open Book Collective.
