URI, URN e URL, una questione di definizioni : universal versus uniform

This article deals with the concepts of “Uniform Resource Indicator” (URI), “Uniform Resource Names” (URN), “Uniform Resource Characteristics” (URC) and “Uniform Resource Locator” (URL). Although it is not exhaustive because of the vastness of the topic, this article aims to offer a view on the topic to anyone who works and manages with remote electronic resources (RER) in their different aspects and different points of view. The analysed documents are: RFC Request for Comments (available in the IETF Internet Engineering Task Force’s website)and some drafts drawn up by the working groups within W3C The World Wide Web Consortium

From e-trash to e-treasure: how value can be created by the new e-business models for reverse logistics

Reverse logistics, that is, all operations related to the reuse of used products, excess inventory and packaging materials, gain increasing attention globally both for their promising financial potentials, the sustainable growth alternative they offer and the environmental positive impact they have. In this paper, we introduce reverse logistics and we explain how the adoption of e-commerce provides new possibilities to existing business models and what are the new e-business models in reverse logistics that have emerged. We compare these three new e-business models, namely, returns aggregators, specialty locators and integrated solution providers on a number of aspects and identify keys for their competitive advantage. Finally, we discuss conceptual and actual opportunities for these e-business models to thrive and advance and present some e-commerce tools that are being developed with the aim to address the distributed, dynamic and knowledge-intensive aspects of applications that contribute to the advancement of e-businesses in the field of reverse logistics.e-commerce;Reverse logistics;e-business models

NASA STI Program Coordinating Council Twelfth Meeting: Standards

The theme of this NASA Scientific and Technical Information Program Coordinating Council Meeting was standards and their formation and application. Topics covered included scientific and technical information architecture, the Open Systems Interconnection Transmission Control Protocol/Internet Protocol, Machine-Readable Cataloging (MARC) open system environment procurement, and the Government Information Locator Service

Web Based Students' Attendance System (WSAS)

A web based students’ attendance system is an appropriate solution for teachers and parents to inform the parents about their students' attendance status in school via SMS and Email services as well as to enhance the communication between teachers and parents. Research Design Methodology was adopted in this project with its five stages, which includes: Awareness of problem, Suggestion (integrated with System Development Methodology), Development (integrated with Object Oriented Development Life Cycle approach), Evaluation, and Conclusion. The prototype was developed to determine, analysis, test, and validate the user's requirements in order to rate the usability test of this system. Furthermore, the prototype was evaluated by using USE questionnaire and the usability results was presented and discussed as well

The artifactualization of reference and "substances" on the Web. : Why (HTTP) URIs do not (always) refer nor resources hold by themselves (post-print)

ISSN 2155-9708, http://www.apaonline.org/APAOnline/Publication_Info/Newsletters/APAOnline/PublicatioInternational audienceIn this paper we show that URIs, sometimes dubbed "philosophical proper names, in fact do not always refer as proper names does. We provide an account explaining why, centered around the notion of "resource", central to webarch, and that we qualify ontologically

Personalizing the web: A tool for empowering end-users to customize the web through browser-side modification

167 p.Web applications delegate to the browser the final rendering of their pages. Thispermits browser-based transcoding (a.k.a. Web Augmentation) that can be ultimately singularized for eachbrowser installation. This creates an opportunity for Web consumers to customize their Web experiences.This vision requires provisioning adequate tooling that makes Web Augmentation affordable to laymen.We consider this a special class of End-User Development, integrating Web Augmentation paradigms.The dominant paradigm in End-User Development is scripting languages through visual languages.This thesis advocates for a Google Chrome browser extension for Web Augmentation. This is carried outthrough WebMakeup, a visual DSL programming tool for end-users to customize their own websites.WebMakeup removes, moves and adds web nodes from different web pages in order to avoid tabswitching, scrolling, the number of clicks and cutting and pasting. Moreover, Web Augmentationextensions has difficulties in finding web elements after a website updating. As a consequence, browserextensions give up working and users might stop using these extensions. This is why two differentlocators have been implemented with the aim of improving web locator robustness
