web 2.0
- 3. Within 15 years the Web has grown from a group work tool for scientists at CERN into a global information space with more than a billion users. Currently, it is both returning to its roots as a read/write tool and also entering a new, more social and participatory phase. These trends have led to a feeling that the Web is entering a ‘second phase’—a new, ‘improved’ Web version 2.0. 'Web 2.0', it means using the standards which have been produced by all these people working on Web 1.0.“ Web 1.0 was all about connecting people. It was an interactive space, and I think Web 2.0 is of course a piece of jargon, nobody even knows what it means. If Web 2.0 for you is blogs and wikis, then that is people to people. INTRODUCTION
- 4. A second phase in the development of the world wide web. From a collection of websites to a complete platform of interactive web applications for end users of the web. It is a social software which enables online interaction,facilitates virtual and creates virtual environments where people can collaborate or create virtual communities.
- 5. Though there is a controversy still going on over the definition of Web 2.0, yet it has some basic common characteristics. These include: --- Web 2.0 use network as a platform as it deliver or receive applications thoroughly via a browser. Users gets, manipulates and controlled the data on the site. Participatory architecture in which user can add or edit value to the application according to their requirement. A rich, interactive, user-friendly interface based on Ajax or similar frameworks. Some social-networking aspects. Enhanced graphical interfaces such as gradients and rounded corners (absent in the so-called Web 1.0 era). CHARACTERISTICS
- 6. A web 2.0 website may usually feature a number of following techniques: Rich Internet application techniques, optionally Ajaxbased. Cascading Style Sheet, CSS . Semantically valid XHTML markup and the use of Microformats. Organization and collection of data in RSS/Atom. Clean and meaningful URLs. Excessive use of folksonomies (in the form of tags or tagclouds). Use of wiki software either completely or partially (where partial use may grow to become the complete platform for the site) partially, e.g. the LAMP solution stack. XACML over SOAP for access control between organizations and domains . Blog publishing. Mashups (A mix up of content and Audio usually from different musical style). REST or XML Webservice APIs.

- 9. Thats web 2.0. There are a lot of things that get lumped into web 2.0, but thats it in a nutshell. Everything else that gets pulled in, AJAX, rounded corners, community, is just window dressing. Web 2.0 isnt a technology, its a change in how the technology is used. CONCLUSION
