Current proposals for Web services infrastructures focus on centralized approaches such as UDDI. However, with the growing number of Web services available on the Web, such a centralized approach quickly becomes impractical. In this paper, we present a novel distributed Web services catalog system, to support decentralized Web service publication and discovery. By utilizing the distributed hash table (DHT) functionality of peer-to-peer (P2P) computing, Web service catalog information is routed directly to each node in this system, and each node shoulders part of the catalog. But in P2P network, every peer is equally treated, and it does not allow peers with common business interest to federate partnerships. In fact, most applications only focus on publication and discovery of services with interest to their respective business domains. In our work, we have made improvements for this limitation, and proposed the hierarchical Web services catalog system, which enables efficient Web service publication and discovery within a specific business domain. Our initial experiments have shown that the distributed catalog system has good scalability.
