ABSTRACT

Web Services are interacting to meet the business objectives on the Internet. These interactions are modeled using standard language and called as Web service choreography language. The successful interactions are dependent on functional as well as non functional feature of these services. The non functional features are based on time and space related values. The space related values may be considered as location preferences of the web service. These location preferences have been considered as location affinity. This location affinity plays an important role in the successful completion of web service choreography. In this paper, the operational semantics of web service choreography has been proposed with the location affinity which is derived from the web service. A methodology for computation of Location Affinity of a Role and Web Service Choreography has proposed.
