Though Diamond Open Access is widely considered the most progressive publishing form for Open Access journals, Diamond Open Access journals face various challenges including (technological) standardisation, securing sustainability for journals and juggling a broad set of workflows while depending largely on voluntary work. The project CRAFT-OA (Creating a Robust Accessible Federated Technology for Open Access) aims to help standardize Diamond Open Access journals by offering technological innovations available to all Diamond Open Access journals alike. Furthermore, in cooperation with the DIAMAS project, CRAFT-OA will foster a community of practice, further enhancing Diamond Open Access publishing by uniting the scholarly community behind common goals. The proposed poster will include an overview of the key objectives of the project as well as a section dedicated to explaining which steps the project teams aim to take in order to make these goals become reality. Additionally, the poster will include a visualization of how the collaboration among the project group DIAMAS, CRAFT-OA and PALOMERA is set up. It will also show how these collaborations work on a structural level. Specifically, it will be explained how the results of DIAMAS and CRAFT-OA complement each other and will be crucial to set up a Capacity Centre supporting institutional Diamond Open Access publishers by providing all information, best practice guidelines, workflows and training materials relating to Diamond Open Access in one place.
