Web 3.0 as Different Formats of Web
The Semantic Web
The term ?Semantic Web? refers to "Defined" Web that is an alliance of World Wide Web Consortium (W3C) and others to provide a standard for defining data structures on the Web. Semantic Web refers to the use of XML-tagged data that matches the Resource Description Framework (RDF).
Sometimes it is refers to "Web 3.0," that is a debatable topic, but in the form of Web 3.0, the main goal of the Semantic Web becomes to identify exact required data that matches the keywords. e.g. if we search Web 3.0 in Google / yahoo / msn or any advance search engines using specific key words, there are millions of web pages appears on the window in which only very few have some information and all other pages are worthless.
Web 3.0 in terms of Semantic Web is the third generation of World Wide Web in which machines can read sites similar to human being and also follows your instructions. For example if you order to check your schedule against the schedules of all the dentists and doctors within a 10-mile radius if follows tour order and provide the appropriate information.
The 3D Web
3-D refers to the three dimensional design that represents the virtual looks of any object from three different sides simultaneously. A user can view the true picture of any building, any location or any object and walk through the location without leaving the computer desk on his/her system. Though these are the virtual pictures but seem to be real. These technologies are extensively being used in a wide range of services like computer games, Virtual Reality (VR) models and Multimedia solutions.
Now, 3-D technology has come on the Internet and has become a new trend of Web. Now user can go house hunting across town or take a tour of the world or can walk through a Second Life?style virtual world, surfing for data and interacting with others in 3D. The 3d web is being used massively in online computer games, virtual world tour, Geospatial engineering, online high tech research, online software development, online shopping, online telecommunication and social networking sites. Google Earth, Wiki Earth, MySpace, You Tube are the biggest examples of 3D web users.
The terms Media-Centric Web refers to the web where users can find true similar graphics and sound on the other media, not just the keywords. e.g. if users searches any favorite movie/ graphics/ music in the search engines, can find the exact desired thing on the other media.
The Pervasive Web
The pervasive web refers the uses of web in the wide range of area in which the web has now been reached not only in computers and cell phones but also in clothing, appliances, and automobiles and much more, e.g. web based bedroom windows that checks weather and self open or close it according to climate.
Web 3.0 in terms of pervasive web refers to those websites, which are going to be transformed into web services and will depict and expand their information to the world.
