摘要
According to the existing multidimensional description idea for services,the authors designed a data model for a digital library service registry based on the IESR data model.This DLSR data model consists of five core entities:service,business,agent,collection and method.It offers an efficient way to release and discover digital library services.At the end of this paper,a mapping from the DLSR data model to the UDDI data model is proposed,which provides a technical solution to implement a DLSR system based on UDDI registry center.Both the data model and the mapping solution have been applied to the development of the OFSR system and proved to be effective.
