Scaling up Service Composition with Downloadable Directory Digests
نویسندگان
چکیده
The composition of services that are indexed in a large-scale service directory often involves many complex queries issued by the service composition algorithm to the directory. These queries may cause considerable processing effort within the directory, thus limiting scalability. In this position paper we present a novel approach to increase scalability: The directory offers a compact directory digest that service composition clients can download to solve the hard part of the composition problem locally. In order to obtain the final solution, only a reduced number of simple directory queries is needed.
