Specifications for Implementing Web Feeds in DLXS Kevin S
Hawkins 1/5/2011 5:01:52 PM Page 1 of 5 * SCHOLARLY PUBLISHING OFFICE WHITEPAPER Specifications for implementing web feeds in DLXS Kevin S. Hawkins Executive Summary SPO uses DLXS to deliver nearly all of its publications online, but this software does not offer any functionality for web feeds (commonly called RSS feeds). The components of web feeds are reviewed, and recommendations are made for implementing Atom 1.0 web feeds in SPO publications using a script run during releasing which determines which content to push to the feed. Motivations Members of the editorial board of the Journal of Electronic Publishing (collid jep) and SPO staff have requested that web feed functionality be provided for SPO publications. This would allow end users to subscribe to feeds of not only serial content (the obvious use) but in theory any other collection to which content is added, especially on a regular basis. A feed could provide a single notice that a collection has been updated, perhaps with a table of contents (henceforth a small feed), or instead contain separate notices for each item added to the collection (a large feed). Components of a web feed A web feed operates with three necessary components: • a website that syndicates (or publishes) a feed • a feed standard being used by the website • the end user’s news aggregator (feed reader or news reader), which retrieves the feed periodically. A feed is an XML document containing individual entries (also items, stories, or articles). Syndicating a feed The content provider’s website often has buttons (icons called chicklets) to be used by the end user to add a feed to his or her news aggregator. -
Despliegue España-América Latina De Broadcatching E-Learning
Despliegue España-América Latina de Broadcatching e-learning Rafael García Monroy E.T.S.I.T. U.P.M. Departamento Ingeniería de Sistemas Telemáticos e-mail: [email protected] Abstract . Los avances tecnológicos y la eliminación de fronteras que resultan del potente y exponencial despliegue de Internet permiten que compartir vídeos de material educativo de gran calidad sea viable. Ya que las exigencias de los usuarios finales –alumnos- crecen paralelamente a la adopción de los avances mencionados, y las posibilidades reales de mejorar los servicios son una realidad, no queda más que emplear las herramientas existentes para crear nuevos modelos innovadores que mejoren constantemente las plataformas de difusión de conocimiento, pilar del desarrollo sostenible. El siguiente artículo describe el despliegue de un modelo e-learning basado en Broadcatching (BitTorrent, + RSS), a través del cual clases de vídeo grabadas en España podrán ser inmediatamente distribuidas a universidades latinoamericanas con las que se tenga convenio, compartiendo recursos de red y, de gran importancia, diseminando los ficheros educativos con una excelente calidad de contenido. De esta manera, la distancia, el costo de distribución y las limitaciones temporales pasan a segundo plano, permitiendo que los contenidos educativos de primera calidad tengan un acceso de naturaleza universal. Palabras clave: BitTorrent, broadcatching, e-learning, P2P, RSS, vídeo. 1 Introducción redes de distribución. Y es precisamente este el punto que hay que explotar para que el alumno obtenga el La cooperación en cualquier ámbito conlleva al mejor contenido educativo posible: la obtención de desarrollo sostenible, en que las partes implicadas vídeos de clase de alta definición que son pesados, comparten el fruto de la inversión. -

History Contents
RSS - Wikipedia, the free encyclopedia Page 1 of 6 RSS From Wikipedia, the free encyclopedia (Redirected from RSS feeds) RSS (most commonly expanded as Really Simple RSS Syndication ) is a family of web feed formats used to publish frequently updated works—such as blog entries, news headlines, audio, and video—in a standardized format. [2] An RSS document (which is called a "feed", "web feed", [3] or "channel") includes full or summarized text, plus metadata such as publishing dates and authorship. Web feeds benefit publishers by letting them syndicate content automatically. They benefit readers who want to subscribe to timely updates The RSS logo from favored websites or to aggregate feeds from many sites into one place. RSS feeds can be read Filename .rss, .xml using software called an "RSS reader", "feed extension reader", or "aggregator", which can be web-based, application/rss+xml desktop-based, or mobile-device-based. A Internet standardized XML file format allows the media type (Registration Being information to be published once and viewed by Prepared) [1] many different programs. The user subscribes to a feed by entering into the reader the feed's URI or Type of Web syndication by clicking an RSS icon in a web browser that format initiates the subscription process. The RSS reader Extended XML checks the user's subscribed feeds regularly for from new work, downloads any updates that it finds, and provides a user interface to monitor and read the feeds. RSS formats are specified using XML, a generic specification for the creation of data formats. Although RSS formats have evolved from as early as March 1999, [4] it was between 2005 and 2006 when RSS gained widespread use, and the (" ") icon was decided upon by several major Web browsers. -

Content Syndication in News Aggregators. Towards Devaluation of Professional Journalistic Criterio
Comunicar, n. 59, v. XXVII, 2019 | Media Education Research Journal | ISSN: 1134-3478; e-ISSN: 1988-3293 www.comunicarjournal.com Content syndication in news aggregators. Towards devaluation of professional journalistic criteria La sindicación de contenidos en los agregadores de noticias: Hacia la devaluación de los criterios profesionales periodísticos Dr. Concha Edo is Professor in the Department of Journalism and Global Communication at the Complutense University of Madrid (Spain) ([email protected]) (https://orcid.org/0000-0001-6960-867X) Dr. Juan Yunquera is Assistant Professor in the Department of Journalism and Audio-visual Communication at the University Carlos III of Madrid (Spain) ([email protected]) (https://orcid.org/0000-0002-4062-1659) Dr. Helder Bastos is Professor in the Department of Communication and Information Sciences at the University of Porto ([email protected]) (https://orcid.org/0000-0002-6351-4610) ABSTRACT The growing expansion of Internet access and mass-scale usage of social networking platforms and search engines have forced digital newspapers to deal with challenges, amongst which are the need to constantly update news, the increasing complexity of sources, the difficulty of exercising their function as gatekeepers in a fragmented environment in which the opinions, biases and preconceptions of pundits, their followers, Twitter users, etc. has taken on a new and decisive weight and the mounting pressure to publish certain news items simply because they sell. They must also share audiences with aggregators devoted to the business of disseminating content produced by digital news publishers, blogs and RSS feeds, which is chosen on the basis of search engine algorithms, the votes of users or the preferences of readers. -

Identifier et surveiller les thèmes de rechercher, spécifier les types d’informations, identifier des mots- clés. 2. Sélectionner des sources (avec une sélection plus large 5. que les thèmes à Diffuser/partager surveiller). les résultats 3. Collecter les résultats 4. Analyser les résultats Isabelle Rey, INRIA, Documentary watch on the web, November 2011 : http://www.slideshare.net/riverieux/documentary-watch-on-the-net Enjeux d’une veille ciblée Mieux connaître son environnement Anticiper les évolutions Pour : - Suivre, cibler, gagner du temps - Lutter contre l’infobésité - Aider à la prise de décision En : - Maintenant un flux régulier d’informations appropriées dans des champs d’intérêts précis - Analysant, évaluant les informations et partageant les connaissances produites Les différentes méthodes de la veille Deux méthodes : - Pull : l’utilisateur va chercher les informations (l’approche classique) • Le veilleur va tirer les informations à lui - Push : le service envoie l'information à l’utilisateur • L’information est « poussée » de manière automatique vers le chercheur, en fonction de ses préférences et de critères préétablis par celui-ci. On parle de profils.
