<li>Abstract:
<p>The Semantic Sensor Network (SSN) ontology is an
RDFS/OWL ontology for describing observations made
by sensors implementing specified procedures, the
studied features of interest and the observed
properties, along with samples used in the
observations and the sampling activities that
created them, as well as actuations which follow a
similar semantics and data structure.
