Integrating hypertext with information systems through dynamic mapping

This dissertation presents a general hypertext model (GHMI) supporting integration of hypertext and information systems through dynamic mapping. Information systems integrated based on this model benefit from hypertext function-alities (such as linking, backtracking, history, guided tours, annotations, etc.) while preserving their own computation capabilities. Although systems supporting integration of hypertext and interface-oriented information systems do exist in hypertext literature, there is no existing model or system effectively supporting integration of hypertext and computation-oriented information systems. GHMI makes its major contributions by both extending and specifying the well-known Dexter Hypertext Reference Model. GHMI extends the Dexter model to overcome its limitations. GHMI also maps its capabilities to the extended Dexter model with appropriate specifications to meet the requirements of our dynamic mapping environment. The extended Dexter functions apply bridge laws in the hypertext knowledge base to map information system objects and relationships to hypertext constructs at run-time. We have implemented GHMI as a prototype to prove its feasibility

Authority in the Virtual Sangat : Sikhism, Ritual and Identity in the Twenty-First Century

In her paper Authority in the Virtual Sanga. Sikhism, Ritual and Identity in the Twenty-First Century, Doris Jakobsh analyses the change of authority based on her research on Sikhs on the Internet. She stresses the Web as a ‘third place’ of communication among the Sikhs as well as the phenomenon of new authorities online. However, this does not imply the replacement of the traditional seats of authority, the Akal Takht, SGPC, or gurdwara managements, but one can recognize a significant shift away from these traditional sites of authority toward the ‘new authorities’, the intermediaries of cyberspace. Her analysis shows that this aspect of the Sikh experience brings with it the most profound challenges and, most importantly, a need to bridge the post-modern individual, i.e. ‘Sikh tradition’ intertwined and legitimated by the metanarrative, and the proliferation of new authorities who have become intermediaries of Sikhism online by virtue of their expertise within the digital domain

Consolidation of Cyberjournalism: Progress and Regressions of 20 Years of History

This article is about the evolution of online media in the past 20 years on the Internet considering the following basic features: hypertext, globalization, instantaneity, multimedia convergence, globalization, updating, digital newspaper and magazine libraries, personalization, interactivity. The result we found is a strong disparity between the online media in developed countries compared to the online media in Latin American countries. Although all elements have grown, unfortunately there has been a very limited development in the element of interactivity. This feature is part of the impact and importance of the Information and Communication Technologies (TIC’S). A quantitative methodology based on content analysis and morphological analysis developed in 2000 and 2014 was applied

Migration from client/server architecture to internet computing architecture

The Internet Computing Architecture helps in providing a object-based infrastructure that can be used by the application developers to design, develop, and deploy the ntiered enterprise applications and services. For years of distributed application development, the Internet Computing Architecture has helped in providing various techniques and infrastructure software for the successful deployment of various systems, and established a foundation for the promotion of re-use and component oriented development. Object-oriented analysis is at the beginning of this architecture, which is carried through deploying and managing of finished systems. This architecture is multi-platform, multi-lingual, standards-based, and open that offers unparalleled integration capability. And for the development of mission critical systems in record time it has allowed for the reuse of the infrastructure components. This paper provides a detailed overview of the Internet Computing Architecture and the way it is applied to designing systems which can range from simple two-tier applications to n-tier Web/Object enterprise systems. Even for the best software developers and managers it is very hard to sort through alternative solutions in today\u27s business application development challenges. The problems with the potential solutions were not that complex now that the web has provided the medium for large-scale distributed computing. To implement an infrastructure for the support of applications architecture and to foster the component-oriented development and reuse is an extraordinary challenge. Further, to scale the needs of large enterprises and the Web/Internet the advancement in the multi-tiered middleware software have made the development of object-oriented systems more difficult. The Internet Computing Architecture defines a scaleable architecture, which can provide the necessary software components, which forms the basis of the solid middleware foundation and can address the different application types. For the software development process to be component-oriented the design and development methodologies are interwoven. The biggest advantage of the Internet Computing Architecture is that developers can design object application servers that can simultaneously support two- and three-tier Client/Server and Object/Web applications. This kind of flexibility allows different business objects to be reused by a large number of applications that not only supports a wide range of application architectures but also offers the flexibility in infrastructure for the integration of data sources. The server-based business objects are managed by runtime services with full support for application to be partitioned in a transactional-secure distributed environment. So for the environments that a supports high transaction volumes and a large number of users this offers a high scaleable solution. The integration of the distributed object technology with protocols of the World Wide Web is Internet Computing Architecture. Alternate means of communication between a browser on client machine and server machines are provided by various web protocols such as Hypertext Transfer Protocol and Internet Inter-ORB Protocol [NOP]. Protocols like TCP/IP also provides the addressing protocols and packetoriented transport for the Internet and Intranet communications. The recent advancements in the field of networking and worldwide web technology has promoted a new network-centric computing structure. World Wide Web evolves the global economy infrastructure both on the public and corporate Internet\u27s. The competition is growing between technologies to provide the infrastructure for distributed large-scale applications. These technologies emerge from academia, standard activities and individual vendors. Internet Computing Architecture is a comprehensive, open, Network-based architecture that provides extensibility for the design of distributed environments. Internet Computing Architecture also provides a clear understanding to integrate client/server computing with distributed object architectures and the Internet. This technology also creates the opportunity for a new emerging class of extremely powerful operational, collaboration, decision support, and e-commerce solutions which will catalyze the growth of a new networked economy based on intrabusiness, business -to-business (B2B) and business-to-consumer (B2C) electronic transactions. These network solutions would be able to incorporate legacy mainframe systems, emerging applications as well as existing client/server environment, where still most of the world\u27s mission-critical applications run. Internet Computing Architecture is the industry\u27s only cross-platform infrastructure to develop and deploy network-centric, object-based, end-to-end applications across the network. Open and de facto standards are at the core of the Internet computing architecture such as: Hyper Text Transfer Protocol (HTTP)/ Hyper Text Markup Language (HTML)/ Extensible Markup Language (XML) and Common Object Request Broker Architecture (CORBA). It has recognition, as the industry\u27s most advanced and practical technology solution for the implementation of a distributed object environment, including Interface Definition Language (IDL) for languageneutral interfaces and Internet Inter Operability (MOP) for object interoperability. Programming languages such as JAVA provides programmable, extensible and portable solutions throughout the Internet Computing Architecture. Internet Computing Architecture not only provides support, but also enhances ActiveX/Component Object Model (COM) clients through open COM/CORBA interoperability specifications. For distributed object-programming Java has also emerged as the de facto standard within the Internet/Intranet arena, making Java ideally suited to the distributed object nature of the Internet Computing Architecture. The portability that it offers across multi-tiers and platforms support open standards and makes it an excellent choice for cartridge development across all tiers

Reproduced and Emergent Genres of Communication on the World-Wide Web

The World-Wide Web is growing quickly and being applied to many new types of communications. As a basis for studying organizational communications, Yates and Orlikowski [1, 2] proposed using genres. They defined genres as, “typified communicative actions characterized by similar substance and form and taken in response to recurrent situations” [1, p. 299]. They further suggested that communications in a new media will show both reproduction or adaptation of existing communicative genres as well as the emergence of new genres. We studied this phenomena on the World-Wide Web by examining randomly selected Web pages (100 in one sample and 1000 in a second) and categorizing the type of genre represented. Perhaps most interestingly, we saw examples of genres being adapted to take advantage of the linking and interactivity of the new medium, such as solicitations for help and genealogies. We suggest that Web site designers consider the genres that are appropriate for their situation and attempt to reuse familiar genres
