The aim is to enable cost transparency not only at institutional and national level, but also to facilitate international comparisons. The project focuses on the development of a standardized metadata schema to record, retrieve, and map all publication costs of a scientific institution in a structured form.enhttp://purl.org/coar/access_right/c_abf2persistent identifierspublication costsopenCost metadata schemaperzistentní identifikátorypublikační poplatkyopenCost metadatové schémaEnhancing Cost Transparency: The Role of Persistent Identifiers in the OpenCost Metadata Schemaconference poster
