集成Ｉｎｔｅｒｎｅｔ上大量自治的、异构的数据和计算资源将是今后软件业的主要挑战之一．作为一种应用系统从位于Ｉｎｔｅｒｎｅｔ上的远程服务结点获取数据并进行数据集成处理的机制，Ｉｎｔｅｒｎｅｔ市场越来越受到业界的重视．文中提出了一个面向空间应用系统的Ｉｎｔｅｒｎｅｔ市场模型ＳＭＡＲＴ，通过其提供的服务类型和服务提供者与用户之间的交互方式描述了该模型．最后，讨论了ＳＭＡＲＴ市场模型的一个原型系统ＡＣＴ－ＴＡＰ．
Integrating a large number of autonomous, heterogeneous data and computing resources on the Internet will be one of the major challenges for the software industry in the future. As a mechanism for application system to get data and process data integration from remote service nodes located on the Internet, the Internet market is getting more and more attention from the industry. In this paper, an Internet market model SMART for space application system is proposed, which is described by the type of service it provides and the interaction between service provider and user. Finally, we discuss ACT-TAP, a prototype system of the SMART market model.
