Web 2.0

Web 2.0 (also known as Participative (or Participatory) and Social Web) refers to websites that emphasizes user-generated content, ease of use, participatory culture and interoperability (i.e., compatible with other products, systems, and devices) for end users. move from personal websites to blogs and blog site aggregation, from publishing to participation, from web content as the outcome of large up-front investment to an ongoing and interactive process, and from content management systems to links based on 'tagging' website content using keywords (folksonomy).The Web we know now, which loads into a browser window in essentially static screenfuls, is only an embryo of the Web to come. The first glimmerings of Web 2.0 are beginning to appear, and we are just starting to see how that embryo might develop. The Web will be understood not as screenfuls of text and graphics but as a transport mechanism, the ether through which interactivity happens. It will appear on your computer screen, on your TV set your car dashboard your cell phone hand-held game machines maybe even your microwave oven.Netscape framed 'the web as platform' in terms of the old software paradigm: their flagship product was the web browser, a desktop application, and their strategy was to use their dominance in the browser market to establish a market for high-priced server products. Control over standards for displaying content and applications in the browser would, in theory, give Netscape the kind of market power enjoyed by Microsoft in the PC market. Much like the 'horseless carriage' framed the automobile as an extension of the familiar, Netscape promoted a 'webtop' to replace the desktop, and planned to populate that webtop with information updates and applets pushed to the webtop by information providers who would purchase Netscape servers.It's a story about community and collaboration on a scale never seen before. It's about the cosmic compendium of knowledge Wikipedia and the million-channel people's network YouTube and the online metropolis MySpace. It's about the many wresting power from the few and helping one another for nothing and how that will not only change the world but also change the way the world changes.Blogs, wikis and RSS are often held up as exemplary manifestations of Web 2.0. A reader of a blog or a wiki is provided with tools to add a comment or even, in the case of the wiki, to edit the content. This is what we call the Read/Write web. Talis believes that Library 2.0 means harnessing this type of participation so that libraries can benefit from increasingly rich collaborative cataloging efforts, such as including contributions from partner libraries as well as adding rich enhancements, such as book jackets or movie files, to records from publishers and others.'Nobody really knows what it means... If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along... Web 2.0, for some people, it means moving some of the thinking client side, so making it more immediate, but the idea of the Web as interaction between people is really what the Web is. That was what it was designed to be... a collaborative space where people can interact.''The task before us is to extend into the digital world the virtues of authenticity, expertise, and scholarly apparatus that have evolved over the 500 years of print, virtues often absent in the manuscript age that preceded print'. Web 2.0 (also known as Participative (or Participatory) and Social Web) refers to websites that emphasizes user-generated content, ease of use, participatory culture and interoperability (i.e., compatible with other products, systems, and devices) for end users. The term was invented by Darcy DiNucci in 1999 and later popularized by Tim O'Reilly and Dale Dougherty at the O'Reilly Media Web 2.0 Conference in late 2004. The Web 2.0 framework only specifies the design and use of websites and does not place any technical demands or specifications on designers. The transition was gradual and, therefore, no precise date for when this change happened has been given. A Web 2.0 website allows users to interact and collaborate with each other through social media dialogue as creators of user-generated content in a virtual community. This contrasts the first generation of Web 1.0-era websites where people were limited to viewing content in a passive manner. Examples of Web 2.0 features include social networking sites or social media sites (e.g., Facebook), blogs, wikis, folksonomies ('tagging' keywords on websites and links), video sharing sites (e.g., YouTube), hosted services, Web applications ('apps'), collaborative consumption platforms, and mashup applications. Whether Web 2.0 is substantially different from prior Web technologies has been challenged by World Wide Web inventor Tim Berners-Lee, who describes the term as jargon. His original vision of the Web was 'a collaborative medium, a place where we all meet and read and write.' On the other hand, the term Semantic Web (sometimes referred to as Web 3.0) was coined by Berners-Lee to refer to a web of content where the meaning can be processed by machines. Web 1.0 is a retronym referring to the first stage of the World Wide Web's evolution. According to Cormode and Krishnamurthy, 'content creators were few in Web 1.0 with the vast majority of users simply acting as consumers of content.' Personal web pages were common, consisting mainly of static pages hosted on ISP-run web servers, or on free web hosting services such as GeoCities. With Web 2.0, it became common for average web users to have social-networking profiles (on sites such as Myspace and Facebook) and personal blogs through either a low-cost web hosting service or through a dedicated host (like Blogger or LiveJournal). In general, content was generated dynamically, allowing readers to comment directly on pages in a way that was not common previously. Some Web 2.0 capabilities were present in the days of Web 1.0, but were implemented differently. For example, a Web 1.0 site may have had a guestbook page for visitor comments, instead of a comment section at the end of each page (typical of Web 2.0). During Web 1.0, server performance and bandwidth had to be considered—lengthy comment threads on multiple pages could potentially slow down an entire site. Terry Flew, in his 3rd edition of New Media, described the differences between Web 1.0 and Web 2.0 as a, Flew believed these factors formed the trends that resulted in the onset of the Web 2.0 'craze'. Some common design elements of a Web 1.0 site include: The term 'Web 2.0' was coined by Darcy DiNucci, an information architecture consultant, in her January 1999 article 'Fragmented Future':
