The session will host impulse talks with ample room for discussion. For the first time in the history of the Semantic Web, Archivo offers the possibility to create a Unified Semantic Ontology Space (USOS), a holistic view over all available ontologies. Instead of soft and fuzzy principles such as FAIR, we will discuss hard, implementable criteria to evaluate ontologies in preparation of a well-defined, measurable standard, which will ultimately yield better and more reliable ontologies for industrial applications. Another discussion topic is the central collaboration on links and mappings between ontologies to create a more dense and well-connected web of ontologies
