Dada la necesidad de la Agencia Andaluza de la Energía de mantener el callejero del Inventario de Instalaciones Energéticas Municipales (INVIEM) se plantea la necesidad de utilizar un visor web de edición cartográfica con capacidad de edición para poder realizar las actuaciones oportunas sobre la información espacial, para ello se decide la utilización del estándar WFS/T (Web Feature Service Transactional) y la utilización de software libre en todos los niveles del sistema a implementar. Este desarrollo será el comienzo de una migración completa de todo el sistema actual a una plataforma integrada por completo con productos de software libre

This project is a Web Geographic Information System built on an Open Source geographic structure like MapServer (Minnesota University) and PostgreSQL/PostGIS (object relational database management system). The study case is a web site for expeditions in a specific Brazilian region

ka-Map ("ka" as in ka-boom!) is an open source project that is aimed at providing a javascript API for developing highly interactive web-mapping interfaces using features available in modern web browsers. ka-Map currently has a number of interesting features. It sports the usual array of user interface elements such as: interactive, continuous panning without reloading the page; keyboard navigation options (zooming, panning); zooming to pre-set scales; interactive scalebar, legend and keymap support; optional layer control on client side; server side tile caching

Degut a la falta d'informació, de temps, no saber a on buscar. . . moltes vegades no ens assabentem, o ho fem massa tard, d'events als que ens hauria agradat assistir, com podrien ser concerts,conferències, activitats esportives, etc. L'objectiu d'aquest projecte serà aprofitar les capacitats de les xarxes socials per crear un lloc web que permeti enviar i geolocalitzar events que podran ser revisats i promoguts pels usuaris, de forma que es pugui suplir aquesta mancança. La solució implementada haurà de proporcionar les següents funcionalitats: enviament d'events (permetrà afegir les dades principals d'un event i geolocalitzar-lo en el mapa); organització de la informació (es disposarà de categories i metacategories per agrupar els events, a més d'un sistema d'etiquetes que facilitarà les cerques en el contingut del web); exploració dels events existents (mitjançant el mapa es podrà veure les dades de qualsevol event); sistema de votació (atorgarà la capacitat per poder decidir quina informació és més rellevant); agenda personal (servirà per registrar events i d'aquesta manera poder rebre notificacions que informin de canvis o simplement que serveixin com a recordatori); comunicació entre usuaris (es realitzarà a través de comentaris al peu dels events i/o d'un xat intern); sindicació web (distribuirà el contingut utilitzant l'estàndard RSS; disponibilitat d'una API simple (permetrà l'accés a certa informació des d'aplicacions externes)

En la web del Institut Cartogràfic de Catalunya se puede navegar por la cartografía oficial de Catalunya, así como descargarla en diferentes formatos, gracias a la aplicación Vissir2, evolución de la histórica Visir (VISor del Servidor de Imágenes Ráster). Nos propusimos que esta nueva versión superase ciertas limitaciones de la herramienta existente: debía poder evolucionar fácilmente en el tiempo, y acercar el uso de nuestros datos y servicios al público más amplio posible. Por ello, se optó por una aplicación basada en software libre y orientada a servicios web con protocolos estándar. En la parte de cliente se ejecuta OpenLayers, una aplicación Javascript muy completa y fácilmente adaptable. En la parte del servidor, TileCaché sirve los datos cartográficos rápidamente y siempre actualizados gracias a una adaptación propia. Pero Vissir2 también utiliza servicios web de producción propia para la impresión, la localización de topónimos, la conversión de coordenadas o la consulta de productos descargables, todos ellos con un protocolo ligero y sencillo. Gracias a esta aplicación los usuarios pueden hacer búsquedas predictivas de topónimos, enlazar a una vista determinada, incrustar un pequeño mapa en su web, descargar un jpeg con la vista actual –o imprimirla–, descargar los datos en diversos formatos, consultar la leyenda del mapa, medir longitudes y áreas, transformar coordenadas, consultar la fecha de elaboración de un producto determinado, o superponer capas con transparencia

Our work is focused on alleviating the workload for designers of adaptive courses on the complexity task of authoring adaptive learning designs adjusted to specific user characteristics and the user context. We propose an adaptation platform that consists in a set of intelligent agents where each agent carries out an independent adaptation task. The agents apply machine learning techniques to support the user modelling for the adaptation process

Hypermedia systems based on the Web for open distance education are becoming increasingly popular as tools for user-driven access learning information. Adaptive hypermedia is a new direction in research within the area of user-adaptive systems, to increase its functionality by making it personalized [Eklu 961. This paper sketches a general agents architecture to include navigational adaptability and user-friendly processes which would guide and accompany the student during hislher learning on the PLAN-G hypermedia system (New Generation Telematics Platform to Support Open and Distance Learning), with the aid of computer networks and specifically WWW technology [Marz 98-1] [Marz 98-2]. The PLAN-G actual prototype is successfully used with some informatics courses (the current version has no agents yet). The propased multi-agent system, contains two different types of adaptive autonomous software agents: Personal Digital Agents {Interface), to interacl directly with the student when necessary; and Information Agents (Intermediaries), to filtrate and discover information to learn and to adapt navigation space to a specific student

Search engines - such as Google - have been characterized as "Databases of intentions". This class will focus on different aspects of intentionality on the web, including goal mining, goal modeling and goal-oriented search. Readings: M. Strohmaier, M. Lux, M. Granitzer, P. Scheir, S. Liaskos, E.

The Web is now so ingrained in our lives that it is easy to forget that it is less than twenty years old. But the History of Web goes back much further, to the pioneering technologists who built the first hypertext systems and the men and women before them who imagined great libraries of interconnected information that would augment human intellect and drive civilization forward. In this lecture we will explore the pre-digital origins of the Web, look at how it developed into the mass communication system we have today, and speculate on the next stages of its evolution in the context of Web Science and Social Media.

Web 2.0 is sometimes described as the read/write web, giving everyday users the chance to create and share information as well as to consume information created by others. Social media systems are built on this foundation of participation and sharing, but what is the mindset of these users, and are they quite so everyday as we might suppose? The skills and attitudes held by users can be described as their literacy, and there has been a lot of debate over the last few years about how to describe these literacies, and design for them. One field that has been changed radically by this notion is Technology Enhanced Learning (TEL) where a fierce debate has raged about the potential of a new generation of highly literate digital natives, and Edupunks have argued for open and personal systems that challenge traditional models of institutional control. In this session we look at the arguments surrounding digital literacy and examine TEL as an example of how social media can change an application domain.

Building software for Web 2.0 and the Social Media world is non-trivial. It requires understanding how to create infrastructure that will survive at Web scale, meaning that it may have to deal with tens of millions of individual items of data, and cope with hits from hundreds of thousands of users every minute. It also requires you to build tools that will be part of a much larger ecosystem of software and application families. In this lecture we will look at how traditional relational database systems have tried to cope with the scale of Web 2.0, and explore the NoSQL movement that seeks to simplify data-storage and create ultra-swift data systems at the expense of immediate consistency. We will also look at the range of APIs, libraries and interoperability standards that are trying to make sense of the Social Media world, and ask what trends we might be seeing emerge.
