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.

在本研究中，我们探讨以XML为基础的资讯系统架构，使其具有超文字系统的弹性与可操作性。该体系结构还旨在提供完整性约束和多媒体信息的管理设施。本研究之主要成果如下：1.多媒体信息三维图形的质量改进：提高了多媒体信息三维图形的质量.基于Web的信息系统的设计与实现为了解决多媒体信息在Web系统中的无缝利用问题，我们设计并实现了一个灾害信息共享系统ONIGIRI。在这个实现中，我们已经澄清了问题，最终用户不能很容易地将多媒体内容上传到服务器.在视频内容的使用中，为了减少网络流量和磁盘I/O的工作量，客户端访问应该在视频服务器之间进行适当的分配。因此，我们研究了在基于Linux的集群计算机上构建视频服务器的基础实验.超媒体内容的开发和使用环境为了在网络分布式环境下将包括视频数据在内的超媒体内容创建为XML（SMIL格式）文档，我们设计并开发了一个SMIL创作工具。此外，我们还开发了视频内容的基本访问控制设施。
