Web 1.0 – That Geocities & Hotmail era was all about read-only content and static HTML websites. People preferred navigating the web through link directories of Yahoo! and dmoz.
Web 2.0 – This is about user-generated content and the read-write web. People are consuming as well as contributing information through blogs or sites like Flickr, YouTube, Digg, etc. The line dividing a consumer and content publisher is increasingly getting blurred in the Web 2.0 era.
Web 3.0 – This will be about semantic web (or the meaning of data), personalization (e.g. iGoogle), intelligent search and behavioral advertising among other things.
If that sounds confusing, check out some of these excellent presentations that help you understand Web 3.0 in simple English. Each takes a different approach to explain Web 3.0 and the last presentation uses an example of a "postage stamp" to explain the "semantic web".

Most of the web users are well known about some common terminologies: web1.0, web2.0 and web3.0. So what are the uses of these terminologies? What are differences between them? After the invention of World Wide Web the idea behind the technology has been absolutely changed. It opens the new way to see the world through internet. It makes our day to day life easier in all around. We can easily operate our business globally. We can join a MNC and able to work from home easily.

The term Web2.0 was first introduced by Oandrsquo;Reilly during the brainstorming discussion MediaLive International. The information available in this form is quite different from the past web1.0. It began in 2002 with new ideas to exchange as well as share the content such as Wiki, Weblogs, Widgets, and Tagging etc.
Key difference between web1.0 and web2.0
In Web 1.0 it is only for read. But in web2.0 you can express yourself by writing.
The former was only for corporate bodies. And the later is about you and your communities.
In web.20 you not only interact with site and webmaster you can also communicate with others who access that website.
Web 1.0 was the age of one and only language i.e. HTML web 2.0 is the field of XML.
While web1.0 was depended on advertising, web 2.0 has been popularized by word of mouth.
Previously was meant for website but web 2.0 is not for site it is also about blogs.
In Web 1.0 there was nothing to exchange. Everything was about one way. Through the emergence of web 2.0 you can exchange your thoughts with other and easily converse with them.
The Web 3.0 could be defined as semantic web, personalization like iGoogle, My Yahoo etc.
The semantic web is a more developed extension of WWW. Wit the help of this technology the web content can be conveyed not only in form of natural language, but also be readable by software agent which letting them to locate, share and assemble information more easily. The concept comes out from Sir Tim Berners-Lee the director of W3C with the vision to make the web medium for exchanging the data, information knowledge.
Other features of web 3.0
- It will be more portable and personal.
- More focused on the preferences of individuals (Me-onomy)
- Advertising oriented.
- Widgets with drag and drop facilities.
- Dynamic content.
- User behavior, user engagement etc.

- Some significant features of web 2.0 technology
- Clean and Simple design
- Number of columns is few.
- Simple navigation which is fixed in every pages of the site.
- Central layout

What is the Semantic Web?
The Semantic Web is a web that is able to describe things in a way that computers can understand.- The Beatles was a popular band from Liverpool.
- John Lennon was a member of the Beatles.
- "Hey Jude" was recorded by the Beatles.
Sentences like the ones above can be understood by people. But how can they be understood by computers?
Statements are built with syntax rules. The syntax of a language defines the rules for building the language statements. But how can syntax become semantic?
This is what the Semantic Web is all about. Describing things in a way that computers applications can understand it.
The Semantic Web is not about links between web pages.
The Semantic Web describes the relationships between things (like A is a part of B and Y is a member of Z) and the properties of things (like size, weight, age, and price)
 * | "If HTML and the Web made all the online documents look like one huge book, RDF, schema, and inference languages will make all the data in the world look like one huge database" Tim Berners-Lee, Weaving the Web, 1999 |
The Resource Description Framework
The RDF (Resource Description Framework) is a language for describing information and resources on the web.Putting information into RDF files, makes it possible for computer programs ("web spiders") to search, discover, pick up, collect, analyze and process information from the web.
The Semantic Web uses RDF to describe web resources.
If you want to learn more about RDF, please read our RDF tutorial.
How can it be used?
If information about music, cars, tickets, etc. were stored in RDF files, intelligent web applications could collect information from many different sources, combine information, and present it to users in a meaningful way.Information like this:
- Car prices from different resellers
- Information about medicines
- Plane schedules
- Spare parts for the industry
- Information about books (price, pages, editor, year)
- Dates of events
- Computer updates
Can it be understood?
The Semantic Web is not a very fast growing technology.One of the reasons for that is the learning curve. RDF was developed by people with academic background in logic and artificial intelligence. For traditional developers it is not very easy to understand.
One fast growing language for building semantic web applications is RSS. If you want to learn more about RSS, please read our RSS tutorial.
