基于RM-ODP模型的G-WebService的设计

A Design for G-WebService Based on RM-ODP Model

1引言 从信息技术发展历史来看,实现信息的共享和交换是互联网技术发展的初衷.而更深一层次,实现各类应用之间的通信和互操作,是目前最迫切的需求,即从数据、信息共享交换为核心到服务之间通信、互操作为核心是互联网目前发展的总趋势.

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 architecture ,G-WebService frame work, which is the definite substitute of WebGIS, will change the existing spatial information 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.
