Abstract

While Web Services already provide distributed operation execution, the registration and discovery with UDDI is still based on a centralized repository. In this paper we propose a distributed XML repository, based on a Peer-to-Peer infrastructure called pXRepository for Web Service discovery. In pXRepository, the service descriptions are managed in a completely decentralized way. Moreover, since the basic Peer-to-Peer routing algorithm cannot be applied directly in the service discovery process, we extend the basic Peer-to-Peer routing algorithm with XML support, which enables pXRepository to support XPath-based composite queries. Experimental results show that pXRepository has good robustness and scalability.
