Web service directory is an important component of SOA-oriented urban spatial information sharing platform. The current UDDI and UDDI-based UBR have been poorly used actually. One the one hand, the business services of urban spatial information sharing platform have some characteristics such as diversity, complexity and security, so the increase of Web services make the maintenance of UBR become very difficult. On the other hand, because there is no corresponding exchanging and connecting mechanism among the private services registry libraries, it results in the new services island among each UGIS. Aiming at the problems mentioned above, the paper designs and implements a distributed Web service directory in SOA-oriented urban spatial information sharing platform. According to the characteristics of urban spatial information sharing services, through distributed portal service directory and node service directory, it can reasonably organize private or semi-private services registered libraries and easily implement mutually communications among them. It can transfer the business services to all UGIS information node service directory, avoid the implementation bottleneck and the difficulties of information maintenance which caused by the centralized model and improve the SOA-based application services availabilities.
