This deliverable provides requirements on ontology tools and ontologies and criteria for selection of further cases. Specifically, we describe the state of the art of the initial demonstrators, addressing the relevant to the project needs, state of the affairs in the usage of ontologies and ontology tools, and the state of the FAIRness for the data in the demonstrators. We also describe how we collected the initial demonstrator descriptions and requirements, namely with surveys and through a dedicated demonstrator workshop. Further, we list the criteria for the selection of further demonstrators for the projects, and outline our future work.
