Success of any web product and application relies upon how thoughtfully and wisely technology has been implemented for developing and deploying that product -- be it e-commerce product or e-learning product. Alongside pedagogy, application of appropriate technology is the important determinant for an effective and engrossing learning experience of…

This study seeks an affirmative answer to the question whether a knowledge-based approach to system of systems interoperation using semantic web standards and technologies can provide the centralized control of the capability for exchanging data and services lacking in a federation of systems. Given the need to collect and share real-time…

The Open Biomedical Ontology (OBO) Foundry initiative is a collaborative effort for developing interoperable, science-based ontologies. The Basic Formal Ontology (BFO) serves as the upper ontology for the domain-level ontologies of OBO. BFO is an upper ontology of types as conceived by defenders of realism. Among the ontologies developed for OBO…

Enterprise architecture (EA) implementation refers to a set of activities ultimately aiming to align business objectives with information technology infrastructure in an organization. EA implementation is a multidisciplinary, complicated and endless process, hence, calls for adequate education and training programs that will build highly skilled…

The Service Oriented Computing (SOC) paradigm, defines services as software artifacts whose implementations are separated from their specifications. Application developers rely on services to simplify the design, reduce the development time and cost. Within the SOC paradigm, different Service Oriented Architectures (SOAs) have been developed.…

Evolutionary and revolutionary approaches have dominated the study of scientific, technological and institutional change. Yet, being focused on change within a single field, these approaches have been mute about a third, pervasive process. This process is found in a variety of cases that range from open source software to the Monte Carlo method to…

Describes international standards for information technology, including an emerging standard for interchangeable multimedia and hypermedia scripts. Highlights include data interchange standards; HyTime (Hypermedia/Time-Based Structuring Language); DSSSL (Document Style Semantics and Specification Language); SPDL (Standard Page Description…

Data integration is one of the single most challenging tasks any district can face. Fortunately for school districts throughout the country with data scattered in disparate systems, an open specification known as the Schools Interoperability Framework (SIF) is mitigating that challenge. SIF has emerged as a cornerstone of K-12 data warehousing,…

Adaptation and personalization services in e-learning environments are considered the turning point of recent research efforts, as the "one-size-fits-all" approach has some important drawbacks, from the educational point of view. Adaptive Educational Hypermedia Systems in World Wide Web became a very active research field and the need of…

More than a decade ago, the predominant means by which colleges and universities deployed major information systems shifted from in-house development to the acquisition of packaged software. The author of this article suggests, however, that institutionally defined business or academic processes may or may not fit the embedded definition of…

Project CUPID (the Consortium for University Printing and Information Distribution) has created a system for distributed printing over the Internet of finished, high-quality, production documents. Topics include the new printing systems; standards and common procedures; the architecture; extension to software systems; copyrights and the…

Secondary vocational-technical education programs in Mississippi are faced with many challenges resulting from sweeping educational reforms at the national and state levels. Schools and teachers are increasingly being held accountable for providing true learning activities to every student in the classroom. This accountability is measured through…

Describes the layered model of Open Systems Interconnection (OSI); summarizes the three upper and lower layers; and discusses data communications standards associated with specific layers. Architectural concepts are explored, including hierarchy and abstraction, levels of dialogue, internetworking, and end-to-end communication. OSI is compared…

This article examined the search functions for all individual EAD Web sites listed on the Library of Congress Web site in 2003. In particular, the type of search engine, search modes, options for searching, search results display, search feedback, and other features of the search systems were studied. The data analysis suggests that there have…

Explains how the Directory Service (CCITT X.500/ISO 9594) became an international standard in response to the difficulties of keeping data on information network users current and accessible. Uses of X.500 are described, a technical overview is provided, its functions and protocols are assessed, and directory projects and products are discussed.…
