A web service interface puts three kinds of constraints on the users of the service. First, the interface specifies the methods that can be called by a client, together with types of input and output parameters; these are called signature constraints. Second, the interface may specify propositional constraints on method calls and output values that may oc- cur in a web service conversation; these are called consis- tency constraints. Third, the interface may specify temporal constraints on the ordering of method calls; these are called protocol constraints. The interfaces can be used to check, first, if two or more web services are compatible, and second, if a web service A can be safely substituted for a web ser- vice B. The algorithm for compatibility checking verifies that two or more interfaces fulfill each others’ constraints. The algorithm for substitutivity checking verifies that service A demands fewer and fulfills more constraints than service B.","lang":"eng"}],"date_updated":"2021-01-12T07:59:50Z","quality_controlled":0,"conference":{"name":"WWW: World Wide Web Conference"}}
