BlogForever: D3.1 Preservation Strategy Report

This report describes preservation planning approaches and strategies recommended by the BlogForever project as a core component of a weblog repository design. More specifically, we start by discussing why we would want to preserve weblogs in the first place and what it is exactly that we are trying to preserve. We further present a review of past and present work and highlight why current practices in web archiving do not address the needs of weblog preservation adequately. We make three distinctive contributions in this volume: a) we propose transferable practical workflows for applying a combination of established metadata and repository standards in developing a weblog repository, b) we provide an automated approach to identifying significant properties of weblog content that uses the notion of communities and how this affects previous strategies, c) we propose a sustainability plan that draws upon community knowledge through innovative repository design

Accesibilidad a los contenidos audiovisuales en la Web a través de HTML5

Desde hace años asistimos a un continuo incremento de contenido audiovisual como vídeo en la Web, por ello que sea muy importante tener en cuenta requisitos de accesibilidad al incluirlo en la web para que todos los usuarios puedan acceder al contenido independientemente de sus características de acceso y contextos diversos de uso. Un contenido vídeo en la web debe ir acompañado de manera sincronizada de alternativas como subtitulado y audiodescripción entre otros, pero además el agente de usuario (reproductor) a través del cual los usuarios acceden debe ser también accesible. Como solución universal está el nuevo estándar HTML5 aun en desarrollo que proporciona algunas ventajas para la accesibilidad en lo que a contenido audiovisual se refiere. En este proyecto se presenta un estudio de estándares a cumplir para incluir contenido audiovisual en la Web, se valora si el nuevo estándar HTML5 da soporte y como caso de estudio se ha desarrollado un reproductor accesible en HTML5. _____________________________________________________________________________________________________________________In recent years, we have seen a continuous increase of audiovisual content like video on the Web. It is very important to consider accessibility requirements when the video is included in the web page enabling users to have access to the content, regardless of users access features and diverse contexts of use. Video content on the Web must be accompanied by synchronized alternatives such as caption and audio description, furthermore the user agent (player) must be accessible too. A universal solution is the new standard HTML5, although it is still under development. It provides some advantages for accessibility as far as audiovisual content is concerned. In this project, a study is presented, which includes standards and requirements that need to be fulfilled when there is audiovisual content on the Web. A case study with a web accessible player has been developed in order to assess if the new HTML5 standard really offers accessibility requirements support.Ingeniería Técnica en Informática de Gestió

Adding state to declarative languages to enable web applications

On the web, media tend to be encoded in declarative formats, which facilitate accessibility, reuse, and transformation. Web applications, on the other hand, are created with more procedural technology and do not enjoy these benefits. In this thesis we examine how this can be fixed. We examine a small part of the problem space, adaptive time based applications, and investigate how we can extend existing declarative languages to fa

Accesibilidad no intrusiva en la comunicación audiovisual en la web

La brecha digital existe incluso en las economías más avanzadas. Sólo ciertos segmentos de la población se están beneficiando de las Tecnologías de la Información y la Comunicación. Muchas personas quedan excluidas debido a la edad, baja alfabetización, discapacidad o debido a que viven en regiones remotas. La accesibilidad para todos, incluidas las personas mayores y con discapacidad, es un requisito esencial para lograr la tan deseada inclusión social. Pero tal como se pretende demostrar, el hecho de alcanzar la conformidad con las pautas de accesibilidad o las normas establecidas, no es suficiente para garantizar una accesibilidad no intrusiva. El concepto de accesibilidad no intrusiva, aquí propuesto, supone cubrir las necesidades y preferencias de cualquier usuario sin interferencias debidas al requisito de cubrir la necesidad o preferencia de un grupo determinado de usuarios que, por su situación de discapacidad, en su más amplio sentido, lo requieran. Quizás donde resulta más molesta o inoportuna la «accesibilidad intrusiva» es en los contenidos multimedia en la web, por lo que el modelo accesibilidad no intrusiva aquí propuesto se centra, precisamente, en ese tipo de contenidos. De manera que el objetivo general de esta tesis es definir un modelo de presentación de contenidos multimedia que, cumpliendo con los requisitos de accesibilidad, no genere ningún tipo de intrusividad en la experiencia de uso. Por tanto, sus objetivos específicos son: a) identificar los elementos que pueden resultar intrusivos en la presentación de contenido multimedia, b) determinar los requisitos que han de cumplir en el modelo que se propone, c) diseñar las interfaces necesarias para garantizar la libertad y comodidad del usuario y, d) validar el modelo diseñado..

The Missing Link: An Introduction to Web Development and Programming

Web development is an evolving amalgamation of languages that work in concert to receive, modify, and deliver information between parties using the Internet as a mechanism of delivery.While it is easy to describe conceptually, implementation is accompanied by an overwhelming variety of languages, platforms, templates, frameworks, guidelines, and standards. Navigating a project from concept to completion often requires more than mastery of one or two complementing languages, meaning today’s developers need both breadth, and depth, of knowledge to be effective. This text provides the developer with an understanding of the various elements of web development by focusing on the concepts and fundamentals through the examples within, providing a foundation that allows easier transition to other languages and a better understanding of how to approach their work. The reader will be introduced to topics in a manner that follows most project development methods, from initial conceptualization and design through front end development, back end development, and introducing additional concepts like accessibility and security, while focusing on responsive design techniques. Each section of the text includes opportunities to practice the material and assess increased knowledge after examining the topics.https://knightscholar.geneseo.edu/oer-ost/1016/thumbnail.jp

MediaSync: Handbook on Multimedia Synchronization

This book provides an approachable overview of the most recent advances in the fascinating field of media synchronization (mediasync), gathering contributions from the most representative and influential experts. Understanding the challenges of this field in the current multi-sensory, multi-device, and multi-protocol world is not an easy task. The book revisits the foundations of mediasync, including theoretical frameworks and models, highlights ongoing research efforts, like hybrid broadband broadcast (HBB) delivery and users' perception modeling (i.e., Quality of Experience or QoE), and paves the way for the future (e.g., towards the deployment of multi-sensory and ultra-realistic experiences). Although many advances around mediasync have been devised and deployed, this area of research is getting renewed attention to overcome remaining challenges in the next-generation (heterogeneous and ubiquitous) media ecosystem. Given the significant advances in this research area, its current relevance and the multiple disciplines it involves, the availability of a reference book on mediasync becomes necessary. This book fills the gap in this context. In particular, it addresses key aspects and reviews the most relevant contributions within the mediasync research space, from different perspectives. Mediasync: Handbook on Multimedia Synchronization is the perfect companion for scholars and practitioners that want to acquire strong knowledge about this research area, and also approach the challenges behind ensuring the best mediated experiences, by providing the adequate synchronization between the media elements that constitute these experiences

Architectures for ubiquitous 3D on heterogeneous computing platforms

Today, a wide scope for 3D graphics applications exists, including domains such as scientific visualization, 3D-enabled web pages, and entertainment. At the same time, the devices and platforms that run and display the applications are more heterogeneous than ever. Display environments range from mobile devices to desktop systems and ultimately to distributed displays that facilitate collaborative interaction. While the capability of the client devices may vary considerably, the visualization experiences running on them should be consistent. The field of application should dictate how and on what devices users access the application, not the technical requirements to realize the 3D output. The goal of this thesis is to examine the diverse challenges involved in providing consistent and scalable visualization experiences to heterogeneous computing platforms and display setups. While we could not address the myriad of possible use cases, we developed a comprehensive set of rendering architectures in the major domains of scientific and medical visualization, web-based 3D applications, and movie virtual production. To provide the required service quality, performance, and scalability for different client devices and displays, our architectures focus on the efficient utilization and combination of the available client, server, and network resources. We present innovative solutions that incorporate methods for hybrid and distributed rendering as well as means to manage data sets and stream rendering results. We establish the browser as a promising platform for accessible and portable visualization services. We collaborated with experts from the medical field and the movie industry to evaluate the usability of our technology in real-world scenarios. The presented architectures achieve a wide coverage of display and rendering setups and at the same time share major components and concepts. Thus, they build a strong foundation for a unified system that supports a variety of use cases.Heutzutage existiert ein großer Anwendungsbereich für 3D-Grafikapplikationen wie wissenschaftliche Visualisierungen, 3D-Inhalte in Webseiten, und Unterhaltungssoftware. Gleichzeitig sind die Geräte und Plattformen, welche die Anwendungen ausführen und anzeigen, heterogener als je zuvor. Anzeigegeräte reichen von mobilen Geräten zu Desktop-Systemen bis hin zu verteilten Bildschirmumgebungen, die eine kollaborative Anwendung begünstigen. Während die Leistungsfähigkeit der Geräte stark schwanken kann, sollten die dort laufenden Visualisierungen konsistent sein. Das Anwendungsfeld sollte bestimmen, wie und auf welchem Gerät Benutzer auf die Anwendung zugreifen, nicht die technischen Voraussetzungen zur Erzeugung der 3D-Grafik. Das Ziel dieser Thesis ist es, die diversen Herausforderungen zu untersuchen, die bei der Bereitstellung von konsistenten und skalierbaren Visualisierungsanwendungen auf heterogenen Plattformen eine Rolle spielen. Während wir nicht die Vielzahl an möglichen Anwendungsfällen abdecken konnten, haben wir eine repräsentative Auswahl an Rendering-Architekturen in den Kernbereichen wissenschaftliche Visualisierung, web-basierte 3D-Anwendungen, und virtuelle Filmproduktion entwickelt. Um die geforderte Qualität, Leistung, und Skalierbarkeit für verschiedene Client-Geräte und -Anzeigen zu gewährleisten, fokussieren sich unsere Architekturen auf die effiziente Nutzung und Kombination der verfügbaren Client-, Server-, und Netzwerkressourcen. Wir präsentieren innovative Lösungen, die hybrides und verteiltes Rendering als auch das Verwalten der Datensätze und Streaming der 3D-Ausgabe umfassen. Wir etablieren den Web-Browser als vielversprechende Plattform für zugängliche und portierbare Visualisierungsdienste. Um die Verwendbarkeit unserer Technologie in realitätsnahen Szenarien zu testen, haben wir mit Experten aus der Medizin und Filmindustrie zusammengearbeitet. Unsere Architekturen erreichen eine umfassende Abdeckung von Anzeige- und Rendering-Szenarien und teilen sich gleichzeitig wesentliche Komponenten und Konzepte. Sie bilden daher eine starke Grundlage für ein einheitliches System, das eine Vielzahl an Anwendungsfällen unterstützt

Website accessibility issues in Western Australian public libraries

Website accessibility is a very real and pressing issue for public libraries internationally. Tim Berners-Lee credited with founding the Web, states The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect. (Henry & McGee, 2010). There is wide-spread support for adherence to the Web Content Advisory Guidelines Version 1.0 and 2.0 (WCAG) throughout Federal, State and Local levels of government in Australia. The Guidelines have also been affirmed by the Australian Human Rights Commission, disability advocacy groups such as Vision Australia, and the Australian Library and Information Association. The Australian Government issued a press release in February 2010 which mandates conformance with WCAG 2.0 by 2015 for all government sites. In order to accommodate this, a new transition strategy has been provided by the Australian Government. While adherence to the Guidelines is clearly mandated, the level of adherence within the public libraries in Western Australia has not been tested until now. Public libraries, by their very nature, should be providing an equality of access to their collections and services. This research assesses the level of adherence to the Web Content Advisory Guidelines (Version 1.0 and 2.0) of public libraries within Western Australia. Through on-line website accessibility evaluation tools, manual checklists, surveys and interviews, this research identifies the level of compliance to these Guidelines as well as the implementation barriers and level of understanding within Western Australia. The assessment of the website accessibility of public libraries in Western Australia operated as a case study methodology incorporating both quantitative and qualitative assessment tools. An analysis of the research methods and findings is provided in this dissertation. The findings of the research demonstrate that at present no public library website in Western Australia with an on-line catalogue link, other than the State Library of Western Australia, conforms to the WCAG Version 1.0 or 2.0 at any level of compliance. Libraries identify a number of barriers to implementation of the guidelines including lack of understanding of the necessity of compliance, lack of understanding of the benefits of compliance, time and cost. The theoretical framework suggested in this research suggests that with increased understanding of the issues and increased support, libraries should be in a better position to work toward website accessibility
