With the rapid advance of the Internet, management of structured documents such as XML documents has become more and more important (Marchiori, 1998). As a simplified version of SGML, XML is recommended by W3C (World Wide Web Consortium, 1998a; World Wide Web Consortium, 1998b) as a document description meta-language to exchange and manipulate data and documents on the WWW. It has been used to code various types of data in a wide range of application domains, including a Chemical Markup Language for exchanging data about molecules, the Open Financial Exchange for swapping financial data between banks and banks and customers, as well as a Geographical Markup Language for searching geographical information (Bosak, 1997; Zhang & Gruenwald, 2001). Also, a growing number of legacy systems are adapted to output data in the form of XML documents.

The eXtensible Markup Language (XML) is a World Wide Web Consortium (W3C) recommendation which has widely been used in both commerce and research. As the importance of XML documents increase, the need to deal with these documents increases as well. This chapter illustrates the methodology that has been used throughout the research, discussing all its parts and how these parts were adopted in the research.

On 3rd November, 1993, ESIS announced its Homepage on the World Wide Web (WWW) to the user community. Ever since then, ESIS has steadily increased its Web support to the astronomical community to include a bibliographic service, the ESIS catalogue documentation and the ESIS Data Browser. More functionality will be added in the near future. All these services share a common ESIS structure that is used by other ESIS user paradigms such as the ESIS Graphical User Interface (Giommi and Ansari, 1993), and the ESIS Command Line Interface. A forms-based paradigm, each ESIS-Web application interfaces to the hypertext transfer protocol (http) translating queries from/to the hypertext markup language (html) format understood by the NCSA Mosaic interface. In this paper, we discuss the ESIS system and show how each ESIS service works on the World Wide Web client.

The World Wide Web (WWW) emerged in 1989, developed by Tim Berners-Lee who proposed to build a system for sharing information among physicists of the CERN (Conseil Européen pour la Recherche Nucléaire), the world’s largest particle physics laboratory. Currently, the WWW is primarily composed of documents written in HTML (hyper text markup language), a language that is useful for visual presentation (Cardoso & Sheth, 2005). HTML is a set of “markup” symbols contained in a Web page intended for display on a Web browser. Most of the information on the Web is designed only for human consumption. Humans can read Web pages and understand them, but their inherent meaning is not shown in a way that allows their interpretation by computers (Cardoso & Sheth, 2006). Since the visual Web does not allow computers to understand the meaning of Web pages (Cardoso, 2007), the W3C (World Wide Web Consortium) started to work on a concept of the Semantic Web with the objective of developing approaches and solutions for data integration and interoperability purpose. The goal was to develop ways to allow computers to understand Web information. The aim of this chapter is to present the Web ontology language (OWL) which can be used to develop Semantic Web applications that understand information and data on the Web. This language was proposed by the W3C and was designed for publishing, sharing data and automating data understood by computers using ontologies. To fully comprehend OWL we need first to study its origin and the basic blocks of the language. Therefore, we will start by briefly introducing XML (extensible markup language), RDF (resource description framework), and RDF Schema (RDFS). These concepts are important since OWL is written in XML and is an extension of RDF and RDFS.

The rapid growth of the World Wide Web provides major new opportunities for distributed databases, especially in macromolecular science. A new generation of technology, based on structured documents (SD), is being developed which will integrate documents and data in a seamless manner. This offers experimentalists the chance to publish and archive high-quality data from any discipline. Data and documents from different disciplines can be combined and searched using technology such as eXtensible Markup Language (XML) and its associated support for hypermedia (XLL), metadata (RDF) and stylesheets (XSL). Opportunities in crystallography and related disciplines are described.

Analysis of E-marketing Strategies The Internet has led to an increasingly connected environment, and the growth of Internet usage has resulted in declining distribution of traditional media: television, radio, newspapers and magazines. Marketing in this connected environment and the use of that connectivity to market is e-marketing. E-Marketing embraces a wide range of strategies, but what underpins successful e-marketing is a user-centric and cohesive approach to these strategies. While the Internet and the World Wide Web have enabled what we call New Media, the theories that led to the development of the Internet have been developed since the 1950s. This paper focuses on only e-marketing strategies, not the plan of e-marketing.

İnternet kaynaklarının makinaca anlaşılabilir olmamasından dolayı, kullanıcıların bilgi ihtiyacını karşılamada sorunlar yaşanmaktadır. Kaynakların yapısal olarak gösterilmemesi ve nasıl yorumlanması ge­rektiğinin ilgili kaynağa özgün çözümlerle hal/edilmeye çalışılması, ilk göze çarpan nedenleri oluşturmaktadır. lnternet kaynaklarının gerek sa­yısal ve gerekse de hacimsel olarak çok hızlı artışı göz önünde bu­lundurıJlduğunda, içerik sözcüklere dayalı arama makinalarına ilaveten, otomatik kaynak keşfine ve bilginin harmanlanmasına olanak veren ya­zılım araçlarının gerekliliği ortaya çıkmaktadır. Bu tür yazılım araçlarının başarısı ise, işlenecek kaynakların modellenmesinin standart bir biçimde yapılmasına çok yakından bağlıdır. RDF (Resource Description Fra­mework), böyle bir çabadan doğan anlamsal bir modellemedir ve bu model üzerinde yapılan çalışmalar WWW (World Wide Web) Kon­sorsiyumu tarafından kontrol edilmektedir. DC (Dublin Core) üstveri ele­manları, elektronik katalog bilgilerini tutmak için, RDF"in genişletilebilirlik özelliği kullanılarak tanımlanmıştır. Bu makalede, RDFIDC modeli kul­lanılarak Türkçe elektronik kaynakların içeriklerinin tanımlanmasını sağ­layan H-DCEdit adlı editör aracı tanıtılacaktır. RDF modelinin seri/eştirme sözdizimi olarak SGML (Standard Generalized Markup Language) kul­lanılmıştır. Bu çalışmaya ek olarak, RDF/DC belgelerinin, DSSSL (Do­cument Style Semantics and Specification Language) standardı yar­dımıyla farklı belge biçimlerinde yeniden biçimlenmesi de sağlanmıştır.

Recently, the use of XML continues to grow in popularity, large repositories of XML documents are going to emerge, and users are likely to pose increasingly more complex queries on these data sets. In 2001 XQuery is decided by the World Wide Web Consortium (W3C) as the standard XML query language. In this article, we describe the design and implementation of an efficient and scalable purely relational XQuery processor which translates expressions of the XQuery language into their equivalent SQL evaluation scripts. The experiments of this article demonstrated the efficiency and scalability of our purely relational approach in comparison to the native XML/XQuery functionality supported by conventional RDBMSs and has shown that our purely relational approach for implementing XQuery processor deserves to be pursued further.

More and more, internal applications are being moved from legacy systems into a more flexible Webbased environment. The issue concerning World Wide Web technologies is important to today’s businesses. Decision making in this area is complex and needs to consider carefully the characteristics and needs of the entities employing these technologies. It has furthermore become clear that the Internet, in particular the World Wide Web, is playing an increasingly larger role in how people communicate. Through this research, technologies used to serve dynamic Web content are compared. This comparison includes performance as well as cost issues, the things that professionals in the business world face when deciding the best implementation of Web server technologies. Existing studies cover a limited scope of the overall picture, and research has thus been focused into very narrow aspects of the global entity. However, the continuing developments in Web technologies dictate the need for a broad scope approach to comparative studies in this field. Such a scope is pursued in this research.

Particularly Since the publication of Edward Said’s Orientalism, the issue of representation has loomed large in the consciousness of many Middle East scholars as we ply our trade. While this issue is undeniably important in our research, it may be even more crucial in our teaching. Encountering students whose only exposure to the Middle East has come through the evening news places a heavy burden on a teacher to respond to prevalent stereotypes about the region and replace them with a more complex, contextualized picture. One way to do this is to supplement the use of standard scholarly works on the region with primary documents in which a wide range of Middle Easterners “speak for themselves.” As scholars have pointed out in the Bulletin, the World Wide Web (www) provides many opportunities to do this in new ways. As a political scientist I chose to provide students in my Government and Politics of the Middle East course with these types of primary sources by designing a project in which students studied the strategies and goals of political activists of many stripes, and the responses of governments to them, by consulting the websites of political movements and newspapers.
