Discover SOS into ONTOCAT

Discover SOS into ONTOCAT by SWRLSWRL (Semantic Web Rule Language) :a standard language which uses rules (i.e., if-then statements)to express knowledge in ontologies ObservationOffering (?offering) ∧ hasObservedProperty (?offering, CO) ∧ hasUOM (CO, PPM) ∧ hasObservation (?offering, ?o) ∧ Observation (?o) ∧ hasValue (?o, ?v) ∧ moreThan (?v, 30) → SevereCO (?o) (any string started with ? is an instance that belongs to the class)
