Abstract

A Web service is a programmable Web application accessible using standard Internet protocols. A three-layer architecture has been suggested for Web services: service providers, service brokers, and service requesters. We propose a SOAP-oriented component-based framework to support device-independent multimedia Web services. Two intelligent agents are introduced and embedded into a proxy server and service provider server, respectively. Separating metadata from multimedia content leads to enhance SOAP flexibility. Composite capability/preference profile-based user profile management provides an easy and flexible way to split and adapt multimedia services to appropriate composite devices as well as increasing the flexibility for users to manage multiple devices. Together with an XML/XSL strategy, we ensure device independency of the system. By utilizing local caches, our agents enable the caching and streaming of multimedia transportation. In addition, our framework seamlessly incorporates cutting-edge technologies relating to Web services: SOAP, XML/XSL, and CC/PP.

一个面向soap的基于组件的框架，支持独立于设备的多媒体Web服务

Web服务是可以使用标准Internet协议访问的可编程Web应用程序。对于Web服务，建议采用三层体系结构:服务提供者、服务代理和服务请求者。我们提出了一个面向soap的基于组件的框架来支持与设备无关的多媒体Web服务。引入两个智能代理，并分别嵌入到代理服务器和服务提供者服务器中。将元数据与多媒体内容分离可以增强SOAP的灵活性。基于组合功能/首选项配置文件的用户配置文件管理提供了一种简单而灵活的方法来拆分和调整多媒体服务以适应适当的组合设备，并增加了用户管理多个设备的灵活性。结合XML/XSL策略，我们确保了系统的设备独立性。通过利用本地缓存，我们的代理启用了多媒体传输的缓存和流。此外，我们的框架无缝地集成了与Web服务相关的尖端技术:SOAP、XML/XSL和CC/PP。
