US-Turkey Cooperative Research: Query Languages for XML with Multimedia Presentations

9912229Ozsoyoglu项目描述：该项目支持俄亥俄州克利夫兰凯斯西储大学（CWRU）电气工程与计算机科学研究系Gultekin Ozsoyoglu教授与土耳其安卡拉比尔肯特大学计算机工程与信息科学系Ozgur Ulusoy博士的合作项目。他们计划研究XML的查询语言，XML是可扩展标记语言，被万维网联盟提议作为标准的web标记语言。本研究有两个目标：研究将XML文档存储到数据库中的方法，以及查询这些数据库的方法；用多媒体表示扩展XML，并研究嵌入XML的多媒体表示的存储、传递和查询。XML规范还没有在XML文档中合并基于内容的多媒体数据建模。此外，目前的半结构化数据操作语言和数据模型还不能处理多媒体，更不用说处理web中的XML文档中的表示和同步问题了。本研究将对基于内容的多媒体数据以及XML中的多媒体表示进行建模，修订/合并/整合XML语言提案和多媒体数据/表示语言，并研究由此产生的新定义语言的查询处理问题。范围：该主题被广泛认为是下一代全球信息系统的关键问题领域。XML显然正在成为在Internet上提供数据（出版物和其他数据）的标准。我们正处于XML完整规范的早期阶段，在数据库对XML数据的支持方面也处于初级阶段。CWRU小组在多媒体数据库方面有经验。比尔肯特大学的团队在分布式和实时系统方面拥有丰富的专业知识。该项目的文献和其他资源很容易从网上获得；因此，在土耳其从事这个项目的学生不需要专门的设施。除了与土耳其的一位同事合作外，还将在CWRU设施培训一名土耳其研究生。该项目符合国际项目部（INT）支持互利研究的使命。

9912229Ozsoyoglu Description: This project supports a cooperative project by the Professor Gultekin Ozsoyoglu, Department of Electrical Engineering and Computer Science research at Case Western Reserve University (CWRU), Cleveland, Ohio and Dr. Ozgur Ulusoy, Department of Computer Engineering and Information Science, Bilkent University, Ankara, Turkey. They plan to investigate query languages for XML, the Extensible Markup Language which is proposed as a standard web Markup language by the World Wide Web Consortium. The research has two goals: to study ways of storing XML documents into databases, and querying such databases; and to extend XML with multimedia presentations, and investigate XML-embedded multimedia presentation storage, delivery, and querying. XML specifications do not yet incorporate content-based multimedia data modeling within XML documents. In addition, present semistructured data manipulation languages and data models do not yet deal with multimedia, much less with presentations and synchronization issues in XML documents in the web. This research will model content-based multimedia data as well as multimedia presentations within XML, revise/merge/consolidate XML language proposals and multimedia data/presentation languages, and investigate the query processing issues of the resulting newly defined languages. Scope: The topic is widely recognized as a critical problem area for the next generation of global information systems. XML is clearly emerging as the standard according to which data (publications as well as other data) will be made available on the Internet. We are in the early stages of the full specification of XML and in the infancy of database support for XML data. The CWRU group has experience with multimedia databases. The group at Bilkent has complimentary expertise in distributed and real-time systems. Literature and other resources for the project are easily obtained from the Web; thus students in Turkey working on this project will not need specialized facilities. In addition to the collaboration with a colleague in Turkey, there will be training of a Turkish graduate student at the CWRU facilities. This project fits the mission of the Division of International Programs (INT) for support of mutually beneficial research.
