摘　　要： 本研究给出了一种新的分布式应用系统构造模型——可扩展的独立分布式应用互操作与集成模型XIOM/(eXtensible InterOperation and Integration Model/)，并给出了相应规范。XIOM面向大粒度的分布式独立应用系统的集成与互操作，实现分布不同的应用系统的跨平台、跨语言的通信与数据交换。 随着计算机网络与数据库技术的发展，分布式计算已成为当今计算机软件，特别是计算机应用的新潮流、新模式，新的分布式计算模式、方法及支撑工具与环境不断出现，其中数基于远程对象调用的分布对象/(DistributedObiects/)技术最为典型。但这种方法局限于代码级的过程调用，模型缺少可扩展性，缺少对点对点互操作的透明支持，不适合于大粒度的关系松散的分布式独立应用系统的集成与互操作，而这些正是分布式计算的新要求和新趋势。XIOM就是为解决这些问题而提出的一种新的方法体系，它对上述的分布式计算问题给出了新的完整解决。它中的XITP协议、CSC模式、XAM模型、KBM密钥管理体制以及XOIML和、XEML等标记语言，不仅在XIOM中起重大作用，而且也是相应领域内的有效的新的模型、方法和语言。 XIOM的工作模式是客户／服务器／客户/(CSC/)模式，支持全双工的点对点互操作。XML文档是XIOM的统一的接口数据和消息，XIOM客户通过交换XML文档实现互操作与集成。由于XML的可扩展性，使得XIOM也是可扩展的模型，这点主要体现在XIOM的接口协议XITP上。 XIOM也是一种应用生成框架，它将分布式应用系统抽象并模型化为固定部分和可变部分。固定部分用XIOM消息代理XMA和一系列API实现。可变部分是应用程序的浅层扩允/(XOIM API调用/)。 XIOM中的通信协议是可扩展的接口传输协议XITP/(eXtensible InterfaceTransfer Protocol/)。XITP是面向XM XIOM/(extensible InterOperation and Integration Model/), advanced by the research work, is a new model for the construction of distributed applications. It mainly aims at the solutions to the interoperation and integration of self-existing distributed applications in large granularity, making them communicate and transfer data between different operating systems and different programming languages. With the increasing development in computer network and database technology, the distributed computing has become a new trend and model of computer applications, and increasing new computing models, methods and tools for the distributed computing are coming into being, among which the Distributed Objects technology based on remote object invocations is a good representative. However, the distributed object technology is limited to code level procedure calls, and is inextensible to work models and nontransparent in point to point interoperation supporting. Therefore it is not suitable for the interoperation and integration of self-existing distributed applications in large granularity and with a high independency. XIOM is right to these problems that constitute the new requirements and trends of the distributed computing. It is a completely new method system that gives a new and full solution to the problems mentioned above. Its interoperation protocol XITP, work model CSC, document access model XAM, key distribution and management system KBM. markup language XOIML and CEML, and so on are not only its important parts, but also effective new models, methods and languages in related field. The communication objects in XIOM work in CSC/(Client//Server//Client/) model. CSC is a new model advanced by the research work that is an evolution of the traditional Customer//Server model. It supports full duplex point to point interoperation.
