scope:

The present document specifies the set of SAREF reference ontology patterns [2] for the modelling and the description of any kind of applications-related data/information/systems. The SAREF reference ontology patterns can be applied to different verticals to provide the SAREF suite of ontologies [1] a homogeneous and predictable structure, and to achieve higher semantic interoperability. They extend and are aligned with the core of the following ontologies: W3C&OGC SOSA (Sensing, Observation, Sampling and Actuation) and SSN (Semantic Sensor Network) [i.1], QUDT (Quantity, Unit, Dimension and Type) [i.2], DUL (Dolce+DnS Ultralite Ontology) [i.3]. The present document is based on the requirements and guidelines defined in ETSI TR 103 549 [i.4] and ETSI TR 103 781 [i.5].
