Web 2.0 refers to a large set of ideas and techniques which encourage user interaction, communication, and collaboration, where web acts as a platform.

In short it is the changing trends in the use of World Wide Web technology and web design.

The term “Web 2.0” was coined by O’Reilly in 2004 during a team discussion on a potential future conference about the Web.

The goal of Scientific Information Resource Division, BARC is acquisition, preservation and dissemination of knowledge in all fields of nuclear science and technology and to bring innovations in related fields. The implementation of RSS 2.0 is one such approach. By offering RSS services, LAKSHYA provides readers the updated contents from a wide range of digital resources. In order to clear up some of the inconsistencies between RSS versions and the problems with the way they interoperate, we are under planning & development of a newly standardized syndication system “Atom”.
