Web-Based Geospatial Technology Tools for Metropolitan Planning Organizations

Las aplicaciones y datos geoespaciales son herramientas importantes en las manos de los planificadores de transporte. El advenimiento de la car-tografía basada en la web y el desarrollo de aplicaciones dinámicas de la Internet (RIA) se pueden utilizar para desplegar datos espaciales para hacer disponible fácilmente la información. La aplicación del Transportation Environment Land Use Data Enterprise (TELUDE) desarrollada por el Durham, Chapel Hill, Carrboro Metropolitan Planning Organization (MPO DCHC) combina Sistemas de Información Geográfica (SIG), RIA, y programación web para lograr este objetivo. La aplicación TELUDE transforma las aplicaciones de escritorio y de recolección de datos espaciales en información accesible desde varias ubicaciones para los análisis. La arquitectura, desarrollo, despliegue y funciones de doce herramientas y varias funciones de planificación de transporte se analizan en este documento. Datos provenientes de diferentes fuentes se combinaron mediante secuencias de comandos y aplicaciones a través de la web en un entorno fácil de usar propicio para la presentación de informes y análisis. La aplicación TELUDE demuestra que la combinación de datos espaciales, scripting, programación, tecnología web y de servidores para mejorar la disponibilidad de datos e información para los planificadores de transporte.

Applying model-driven engineering to the development of Rich Internet Applications for Business Intelligence

Business Intelligence (BI) applications have been gradually ported to the Web in search of a global platform for the consumption and publication of data and services. On the Internet, apart from techniques for data/knowledge management, BI Web applications need interfaces with a high level of interoperability (similar to the traditional desktop interfaces) for the visualisation of data/knowledge. In some cases, this has been provided by Rich Internet Applications (RIA). The development of these BI RIAs is a process traditionally performed manually and, given the complexity of the final application, it is a process which might be prone to errors. The application of model-driven engineering techniques can reduce the cost of development and maintenance (in terms of time and resources) of these applications, as they demonstrated by other types of Web applications. In the light of these issues, the paper introduces the Sm4RIA-B methodology, i.e., a model-driven methodology for the development of RIA as BI Web applications. In order to overcome the limitations of RIA regarding knowledge management from the Web, this paper also presents a new RIA platform for BI, called [email protected], which extends the functionalities of traditional RIAs by means of Semantic Web technologies and B2B techniques. Finally, we evaluate the whole approach on a case study--the development of a social network site for an enterprise project manager.

An adaptable and personalized web telecommunication model

During the last decade, improvements in network, software, and hardware capabilities have leveraged the development of rich Internet applications (RIAs) that offer new and better user experiences. This new deal in the landscape of Internet technologies led us to reconsider the integration of telecommunication on the web. Instead of creating yet another artificial bridge between Internet and various telecommunication architectures, we tried to design a brand new communication model adapted to the intrinsic properties of the web. We implemented a prototype built on an innovative container-based mechanism which provides this new web-telco infrastructure with a high degree of flexibility and a complete adaptability to its environment. Then we defined open interfaces to guarantee fine-grained control and personalization of the communication sessions. Finally, we tested this new approach through a live experimental platform in order to measure the impact of our model in real conditions. To date, the experiments have provided compelling results which demonstrate a real interest from end users and new opportunities for services providers and telecom operators.

The use of AJAX in searching a bibliographic database

Purpose – The purpose of this paper is to describe the use of AJAX for searching the Biblioteche Oggi database of bibliographic records.Design/methodology/approach – The paper is a demonstration of how bibliographic database single page interfaces allow the implementation of more user‐friendly features for social and collaborative tasks.Findings – AJAX is an important technique in Web 2.0. It allows the development of rich internet applications that use only one web page. Using AJAX it is possible to improve a bibliographic database's user interface. Thanks to this technology, bibliographic applications will be more flexible for updating and formatting information, simpler in managing session history, and easier for saving data modified by users. Usability tests demonstrated that users have appreciated the new interface, but accessibility remains a problem.Originality/value – The paper highlights the use of a Web 2.0 tool for a relevant application in the library/information world.

Meeting accessibility guidelines: lessons from Australia

The internet is regarded as a hub for information, commerce and education and this raises issues of universal access for citizens being able to participate in a knowledge-driven economy. Universal access to the internet has become a human rights issue that allows all members of a society, including people with disabilities, the right to access its vast repository of information. In Australia, the Disability Discrimination Act of 1992 makes it is unlawful to discriminate against people with disability. However, the Act is not specific about online accessibility. It does not, for instance, include reference to the Web Accessibility Initiative (WAI) Guidelines as does the US Section 508 of the Rehabilitation Act. According to research reported in this paper, we found that the majority of websites in Australian educational institutions have significant obstacles that would make it difficult for people with disabilities to use. The central question posed by this paper is: Why is it that, despite best intentions, policy frameworks, the availability of a wealth of resources, testing devices and so on, many vocational education and training websites and resources fail to comply with the accessibility standards? It concludes that with the rapid development of Rich Internet Applications (RIA) technologies, the ability of education providers to reach accessibility standards becomes even more important as a focus for institutional policy development and implementation.
