text: We present a language for specifying web service interfaces. 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.
