1, 2, 3: the constantly evolving Web

To understand the "Real Time Web", you must know the evolution of the Web as each new "version" of the Web is partly result of the shortcomings of the previous version (techniques, use ...). It also comes complete, not replace it.

Web 2.0

Web 2.0 or collaborative Web / participatory symbolizes the interactive Web where users no longer just a consumer but a producer of information.

– compare des sites/services Web anciens (ce qu'il appelle le Web 1.0) et les nouveaux sites/services Web (ce qu'il appelle le Web 2.0). The genesis of the term "Web 2.0" was in 2003 Lorqui Dale Dougherty - co-founder of the publishing company O'Reilly Media - compare sites / services Web elders (what he calls Web 1.0) and new sites / Web Services (what he calls Web 2.0). Its comparative table of Web services 1.0/Web 2.0 was then taken over by Tim O'Reilly in his seminal article of Web 2.0 in October 2005.

Web 2.0 is no longer a "website" (with its well-defined limits), but rather a web platform based on a set of principles without specific limitations:

• the user becomes a producer of information on media Web that do not belong (eg blog)
• information comes to the Internet through syndication RSS feeds
• Web becomes a personalized management by the user data stream (suitable reader and not necessarily a Web browser, custom display ...)
• Web 2.0 promotes the collective intelligence service as shown in Wikipedia versus Encyclopedia Unniverselle one (each user can edit an article and change it from another Wikipedia)
• the interaction and sharing transform the Web into social media,
• the "Websites" become Web services (eg Google Docs ) ever built by its use by users (via mashups and widgets, a Web service can be created from existing Web services like Google Maps or PayPal ).

Focus on the blog: the blog has allowed many non-computer users to publish on the Web (importance of permalinks to label information and thus be able to share). With the addition of RSS feeds, it also has transformed access to information because information is now on the Internet, it can be edited on other Web sites (and therefore more shareable) and that information can be read on drives other than the web browser. A major point that makes RSS a break there is no interaction between the creator of the RSS and its user (the user uses it without asking his consent to the creator).

« ), wiki et non CMS , divers lecteurs Web et pas seulement les navigateurs Web, avec la multiplication des interactions le web 2.0 ressemble plus à ce qui se passe dans un cerveau que le Web 1.0, coopération et pas contrôle, widgets, mashups, AJAX . Here are the keywords of Web 2.0 and an attitude not a technology, Internet contributor, rich user experience, "an implicit architecture of participation" and not of the publication, and blog permalinks, RSS feeds and syndication (rupture of use need not agree as to use it), interaction, Web platform, Web services, sharing, social media, social networking, social bookmarking, beta permanent SEO and not the domain name, the data stream , data management, decentralization, tags and not categories (unlike the taxonomy folksonomy), multiple Web sources ("long tail") and not just a few reference sites, a system without an owner, open standards, collective intelligence and wisdom of crowds ("Wisdom of Crowds"), and not wiki CMS, various readers, not just Web browsers, with the proliferation of Web 2.0 interactions is more like what happens in a brain that the Web 1.0, cooperation and not control, widgets, mashups, AJAX.

Examples of iconic Web 2.0: Wikipedia , Google Maps , Google Docs , Delicious , Blogger , MySpace , Facebook , YouTube , Flickr .
