Querying a Service from Repository of SMaps

Web Service Composition Using Service Maps

“…Further we have proposed a framework for possible implementation of the technique. Before, [11] we have extended juddi enabling it to store SMaps in a relational database. With this experience we are now implementing our proposed query processor for SMap repository at juddi.…”

“…Earlier in [11] we have discussed on mechanism to specify and find a service that suffices a query. Here, we'll take up the case of a query that needs services from more than one SMap.…”

“…This (I/O parameters) make interface to a SMap module and this needs to be exposed to external world for interested service consumers. In [11] we have specified schemas that store SMaps in a RDBMS. Now, along with these schemas information CP's are to be stored.…”

“…The strategies most followed for service composition are: (i) search by function name (that corresponds to service functionality) (ii) following I/O match among services (iii) matching of service protocols, and these strategies work on interfaces that are exposed to external world. In our earlier work [11] we have argued a meta-description on service, i.e the way it's structured as well as promoted is useful for users to select a service of choice. For such a description we have proposed SMap a means to specify a service.…”
