The "PUDEL" project (Publikationsdienst für wissenschaftliche Datenmodelle und Vokabulare, based at the Saxon Academy of Sciences and Humanities Leipzig) focuses on developing a comprehensive publication service that caters to the specific requirements of data models and vocabularies. The project recognizes the critical role of these resources in facilitating data interoperability, enabling data reuse, and promoting collaborative research across various disciplines. At this point, a second project phase is in preparation. It is planned to extend the prototype and to address the following tasks: exploration and discoverability of data models, further developing of PUDEL as a free and open-source software, and community building and knowledge dissemination.
