The Taxonomy of Digital Research Activities in the Humanities (TaDiRAH ) has by now developed a long and vibrant history. Over the years, it has grown through a wide range of collaborations, driven by international and interdisciplinary exchange as well as the commitment of numerous contributors from the digital humanities community. At present, a new phase is beginning that envisions the collaborative further development of TaDiRAH. Core content and initial language versions are already in place; now we would like to involve the community more closely, bring together existing expertise, and jointly shape the next steps. One key objective is to further develop TaDiRAH sustainably, strengthen its international interoperability, and establish it firmly for the long term. We invite everyone interested to actively contribute — whether through feedback, content contributions, discussions, or participation in linguistic extensions — as we explicitly view the further development of TaDiRAH as a collaborative process. For existing language versions, we are looking for active contact persons who can serve as points of contact and support maintenance, coordination, and further development. At the same time, we would also like to specifically ask who might be interested in contributing to additional translations and linguistic extensions. The technical and conceptual development is carried out transparently via GitHub (https://github.com/dhtaxonomy/TaDiRAH). Changes are documented, discussed, and versioned there. Participation is also possible for people without extensive technical expertise; supporting materials and introductory resources are available (https://zenodo.org/records/20762024). Contributions are possible on different levels: – Editorial and conceptual contributions – Translations and linguistic adaptations – Discussion of terminology, structures, and use cases – Technical support and review – Networking and increasing visibility within the community. Please do not hesitate to contact us: [email protected]. As next steps, additional language versions are planned, particularly Polish (PL) and Turkish (TR). Interested contributors are warmly invited to get involved. Interested individuals are also warmly invited to subscribe to the mailing list: https://www.listserv.dfn.de/sympa/info/tadirah. At present, there are two Germany-based data competence centers with a concrete interest in the further development of TaDiRAH and in sustainably advancing related efforts. HERMES (https://hermes-hub.de) and SODa (https://sammlungen.io/), represented by IGSD e.V. (https://igsd-ev.de), are currently supporting TaDiRAH by increasing its visibility and fostering exchange between projects and communities. At the same time, involving and activating the community also serves to identify potential pathways for the long-term sustainability of the project activities. They contribute to visibility, promote exchange between projects and communities, and support the sustainable institutionalization of these activities. We are delighted to be taking part in this year’s EADH 2026 in Kraków and warmly invite everyone to attend our session. The programme will be available here shortly: https://eadh2026.confer.uj.edu.pl/programme.
