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.

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.

This chapter gives a tutorial on resource description framework (RDF), its XML representation, and Jena, a set of Java-based API designed and implemented to further simplify the manipulation of RDF documents. RDF is a W3C standard which provides a common framework for describing resources in the World Wide Web and other applications. Under this standard framework with the Jena, different resources can be manipulated and exchanged easily, which leads to cost reduction and better efficiency in business applications. In this tutorial, we present some basic concepts and applications of RDF and Jena. In particular, we use a television object to illustrate the usage of RDF in describing various resources being used, the XML syntax in representing the RDF, and the ways Jena manipulate various RDF documents. Furthermore, complete programming codes with detailed explanations are also presented to give readers a better understanding of Jena. References are given at the end for readers’ further investigation.

Application profiles fulfill similar functions to other forms of metadata documentation, such as data dictionaries. The preference is for application profiles to be machine-readable and machine-actionable, so that they can provide validation and processing instructions, not unlike XML schema does for XML documents. These goals are behind the work of the Dublin Core Metadata Initiative in the work that has been done over the last decade to develop application profiles for data that uses the Resource Description Framework model of the World Wide Web Consortium.

A presente pesquisa objetiva propor um modelo de dados abertos conectados (linked open data - LOD), para um conjunto de dados abertos legislativos da Câmara dos Deputados. Para tanto, procede-se à revisão de literatura sobre os conceitos de dados abertos, dados abertos governamentais, dados conectados (linked data), e dados abertos conectados (linked open data), seguido de pesquisa aplicada, com a modelagem de dados legislativos no modelo LOD. Para esta pesquisa foi selecionado o conjunto de dados "Deputados", que contém informações como partido político, unidade federativa, e-mail, legislatura, entre outras, sobre os parlamentares. Desse modo, observa-se que a estruturação do conjunto de dados em RDF (Resource Description Framework) é possível com reuso de vocabulários e padrões já estabelecidos na Web Semântica como Dublin Core, Friend of a Friend (FOAF), RDF e RDF Schema, além de vocabulários de áreas correlatas, como a Ontologia da Câmara dos Deputados italiana e a da Assembleia Nacional Francesa. Conforme recomendação do padrão Linked Data, os recursos foram relacionados também a outros conjuntos de LOD para enriquecimento semântico, como as bases Geonames e DBpedia. O estudo que permite concluir que a disponibilização dos dados governamentais, em especial, dados legislativos, pode ser feita seguindo as recomendações da W3C (World Wide Web Consortium) e, assim, integrar os dados legislativos à Web de Dados e ampliar as possibilidades de reuso e aplicações dos dados em ações de transparência e fiscalização, aproximando os cidadãos do Congresso e de seus representantes.


Last decade observed the exponential growth of World Wide Web (WWW) due to the growing trend of migration of each & every information on the web. In order to design the User Interface (UI) of web based application, a number of frameworks are used such as Bootstrap, WordPress, and Joomla etc. But sometimes the use of Dynamic HyperText Markup Language (DHTML) to design from scratch is preferred over frameworks. In this paper, research was carried out to compare the performance with respect to UI on different parameters of web-portals designed using frameworks viz-a-viz use of DHTML technology. Performance was compared using the tools, GTMetrix and Pingdom. Results can be used to facilitate the decision to select the framework or not, while designing the UI of webpages.

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.

Although its conceptual origins can be traced back a few decades (Bush, 1945), it is only recently that hypermedia has become popularized, principally through its ubiquitous incarnation as the World Wide Web (WWW). In its earlier forms, the Web could only properly be regarded a primitive, constrained hypermedia implementation (Bieber & Vitali, 1997). Through the emergence in recent years of standards such as eXtensible Markup Language (XML), XLink, Document Object Model (DOM), Synchronized Multimedia Integration Language (SMIL) and WebDAV, as well as additional functionality provided by the Common Gateway Interface (CGI), Java, plug-ins and middleware applications, the Web is now moving closer to an idealized hypermedia environment. Of course, not all hypermedia systems are Web based, nor can all Web-based systems be classified as hypermedia (see Figure 1). See the terms and definitions at the end of this article for clarification of intended meanings. The focus here shall be on hypermedia systems that are delivered and used via the platform of the WWW; that is, Web-based hypermedia systems.
