Abstract

Service description is the underlying basis of different service tasks. In this paper, we proposed two service description extensions to enhance the scalability of SOA. First we proposed multi-input operation to increase the flexibility of service interface. Second, we encode service dependency into service description. Service dependency is not only an empirical knowledge for reliable service composition, but it is also a distributed service recommendation and discovery mechanism, which is more scalable than centralized service discovery mechanisms such as UDDI.
