Required predicates: name Optional predicates: aboutURI metadata oneLineDescription providesResource The owl:Restriction on sswap:providedBy refines the class definition so as to prohibit the reasoner from otherwise incorrectly infering that swap;Provider is a rdfs:subClassOf sswap:Resource. sswap:providedBy is not a valid predicate for a sswap:Provider. See sswap:Resource for notes on sswap:providesResource and sswap:providedBy.
