First Public Working Draft: Extensions to the Semantic Sensor Network Ontology

The Spatial Data on the Web Interest Group has published a First Public Working Draft of Extensions to the Semantic Sensor Network Ontology. This specification describes some extensions to the Semantic Sensor Network Ontology, published as a W3C Recommendation in 2017, to enable linking to the ultimate feature-of-interest for an observation, act of sampling, or actuation, and homogeneous collections of observations, in which one or more of the properties may be shared by all members of the collection.
