Based on the Open access workflow model developed in the predecessor project OA-HVerlag, the research team addressing the question of how data exchange between the systems involved in the workflow can be made more robust and compatible. In this project, the academic approach of a communication structure is being developed. This data transfer container will ensure access to project-specific content and systematize and facilitate the transformation of metadata standards for the distribution of the publication on different platforms. In addition, a toolbox of consulting materials for modelling OA workflows were created and a production system for producing OA monographs was developed.
