It is the –machine interpretable– exposure of a –human understandable– command to a network. While a coswot:OperationOfInterest is specific to a service of interest, a coswot:OperationKind is an archetype of operations.</rdfs:comment> <metadata:prefixIRI>coswot:Operation</metadata:prefixIRI> <skos:note xml:lang="en">Typically, a device connected to a given network offers one service for each of its functions of interest, and each service has one operation per command of interest of the function of interest it represents.</skos:note> <skos:note xml:lang="en">An operation may be described in terms of its inputs and outputs using OP coswot:hasInput and coswot:hasOutput. Inputs and outputs of operations typically describe the expected schema or shape of network messages.</skos:note> <rdfs:isDefinedBy rdf:resource="https://w3id.org/coswot/core/services_operations"/> <rdfs:label xml:lang="en">Operation</rdfs:label> <skos:example xml:lang="en">In the set of operations exposed by a smart washing machine on a given network, one may be dedicated to set the water temperature for the washing cycle, and expected as input a enumerated value.
