基于RM—ODP模型的G—WebService的设计

Web Service,as a new standard framework for distributed computing,is to solve the existing problem of cross-platform communication and collaboration between distributed applications. Evolving from the Web Service ar-chitecture ,G-WebService framework, which is the definite substitute of WebGIS, will change the existing spatial infor-mation applications into geo-services. This paper first introduces the Web Service concept and the related standards,and then discusses the G-WebService architecture and implementation from five viewpoints,which is based on RM-ODP.
