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

该项目支持俄亥俄州克利夫兰凯斯西部储备大学(CWRU)电气工程和计算机科学研究系的Gultekin Ozsoyoglu教授和土耳其安卡拉比尔肯特大学计算机工程和信息科学系Ozgur Ulusoy博士的合作项目。他们计划研究可扩展标记语言XML的查询语言，可扩展标记语言是由万维网联盟建议作为标准Web标记语言的。本研究有两个目标：一是研究如何将XML文档存储到数据库中并对其进行查询；二是利用多媒体演示对XML进行扩展，并研究嵌入XML的多媒体演示的存储、传递和查询。XML规范还没有将基于内容的多媒体数据建模合并到XML文档中。此外，目前的半结构化数据操作语言和数据模型还没有处理多媒体，更不用说Web中的XML文档中的表示和同步问题了。这项研究将在XML中对基于内容的多媒体数据和多媒体表示进行建模，修改/合并/合并XML语言建议和多媒体数据/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显然正在成为在互联网上提供数据(出版物和其他数据)所依据的标准。我们正处于完整的XML规范的早期阶段，并且处于对XML数据的数据库支持的初级阶段。CWRU小组在多媒体数据库方面有经验。比尔肯特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，在土耳其从事该项目的学生将不需要专门的设施。除了与土耳其的一位同事合作外，还将在CWRU的设施中培训一名土耳其研究生。该项目符合国际方案司(INT)支持互惠研究的使命。

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.
