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."}],"publication_status":"published","article_processing_charge":"No","fulldoi":"https://doi.org/10.1145/1060745.1060770","date_published":"2005-05-01T00:00:00Z","title":"Web service interfaces","date_created":"2018-12-11T12:09:33Z","acknowledgement":"This research was supported in part by the ONR grant N00014-02-1-0671 and by the NSF grants CCR-0234690 and CCR-0225610.","type":"conference","publisher":"ACM","_id":"4576","status":"public","date_updated":"2026-09-30T14:12:48Z","year":"2005","extern":"1"}]
