 This deliverable introduces the ontologies that have been developed in the context of the InterConnect project to cope with the variety of use cases and services implemented by the Interconnect large scale pilots. According to ontology engineering best practices, the Interconnect ontologies reuse already existing ontologies and, in particular, they extend the SAREF suite of ontologies promoted and maintained by ETSI.
