项目摘要

In this research, we have investigated the architecture for XML-based information systems which have flexibility and operability as hypertext-systems. This architecture also aims for management facility for integrity constraints and multimedia information. The results of this research project are the followings ;1. Quality improvement in 3D graphics for multimedia information.We have improved the quality of 3D graphics presentation for multimedia information.2. Design and implementation of a Web-based information system.In order to clarify the problems to use multimedia information seamlessly in Web-based systems, we have designed and implemented, ONIGIRI, an information shareing system for disasters. In this implementation, we have clarified the problem that end-user can not easily upload the multimedia contents to the server.3. In usage of video contents, it is necessary that the client accesses should be properly distributed among video servers in order to decrease the workload of network traffic and disk I/O.Thus, we have investigated on the basic experiment to construct a video server on a Linux-based clustered computer.4. Development and usage environment for hypermedia contentsIn order to create a hypermedia content, including the video data, as XML (SMIL format) documents on the network distributed environment, we have designed and developed a tool for SMIL authoring. And, we have also developed the basic access control facility for video contents.

在这项研究中，我们研究了基于XML的信息系统的体系结构，这些信息系统具有超文本系统的灵活性和可操作性。该体系结构还旨在用于管理设施的完整性约束和多媒体信息。该研究项目的结果是以下; 1。用于多媒体信息的3D图形的质量改进。我们改善了用于多媒体信息的3D图形演示质量。2。为了阐明在基于Web的系统中无缝使用多媒体信息的问题，我们设计和实施了基于Web的信息系统。在此实施中，我们阐明了最终用户无法轻易将多媒体内容上传到服务器的问题。3。在使用视频内容时，有必要在视频服务器之间正确分发客户端访问，以减少网络流量和磁盘I/O的工作量。因此，我们已经对基本实验进行了调查，以在基于Linux的集群计算机上构建视频服务器。4。 HyperMedia Contents的开发和使用环境命令创建HyperMedia内容（包括视频数据），例如网络分布式环境上的XML（SMIL格式）文档，我们为SMIL创作设计并开发了一种工具。而且，我们还为视频内容开发了基本的访问控制设施。
