Web 3.0 - What’s coming!

Web 3.0 is a term used to describe the future of the World Wide Web. Following the introduction of the phrase “Web 2.0″ as a description of the recent evolution of the Web, many technologists, journalists, and industry leaders have used the term “Web 3.0″ to hypothesize about a future wave of Internet innovation.

Following are some of the key development anticipated in Web 3.0:

API Providers

These are the raw hosted services that have powered Web 2.0 and will become the engines of Web 3.0 — Google’s search and AdWords APIs, Amazon’s affiliate APIs, Lulu’s API etc. a seemingly infinite ocean of RSS feeds, a multitude of functional services. More and more companies will start offering thier service, data, connectivity via thier own APIs.

API Integrators

These are the intermediaries that take some of the hassle out of locating all those raw API services by bundling them together in useful ways. Obvious examples today are the various RSS aggregators, and emerging web services marketplaces like the StrikeIron service.

Web 3.0 Applications

These will not be like the established application categories we are used today, such as CRM, ERP or office, but a new class of composite applications that bring together functionality from multiple services to help users achieve their objectives in a flexible, intuitive and self-evident way.

In nutshell, Web 3.0 will provide;

A new generation of services-based, composite applications that are tailored to fit the work processes that people actually need.

Transforming the Web into a ‘Database’

The first step towards a “Web 3.0″ is the emergence of “The Data Web” as structured data records are published to the Web in reusable and remotely queryable formats, such as XML, RDF, ICDL and microformats. SPARQL technology provides a standardized query language and API for searching across distributed RDF databases on the Web. The Data Web enables a new level of data integration and application interoperability, making data as openly accessible and linkable as Web pages. The Data Web is the first step on the path towards the full Semantic Web.

An evolutionary path to artificial intelligence

Web 3.0 has also been used to describe an evolutionary path for the Web that leads to artificial intelligence that can reason about the Web in a quasi-human fashion. IBM and Google are implementing new technologies that are yielding surprising information such as making predictions of hit songs from mining information on college music Web sites. collaborative filtering services like del.icio.us, Flickr and Digg that extract meaning and order from the existing Web and how people interact with it. Can you build a similar one.

3D Web

Another possible path for Web 3.0 is towards the 3 dimensional vision championed by the Web3D Consortium. This would involve the Web transforming into a series of 3D spaces, taking the concept realised by ‘Second Life’ further. This could open up new ways to connect and collaborate using 3D shared spaces.

Semantic Web

The Semantic Web is an evolving extension of the World Wide Web in which the semantics of information and services on the web is defined, making it possible for the web to understand and satisfy the requests of people and machines to use the web content. Humans are capable of using the Web to carry out tasks such as finding the Finnish word for “cat”, reserving a library book, and searching for a low price on a DVD. However, a computer cannot accomplish the same tasks without human direction because web pages are designed to be read by people, not machines. The semantic web is a vision of information that is understandable by computers, so that they can perform more of the tedious work involved in finding, sharing and combining information on the web.

Currently, the World Wide Web is based mainly on documents written in Hypertext Markup Language (HTML), a markup convention that is used for coding a body of text interspersed with multimedia objects such as images and interactive forms. Metadata tags, for example

provide a method by which computers can categorise the content of web pages.

The semantic web takes the concept further; it involves publishing the data in a language, Resource Description Framework (RDF), specifically for data, so that it can be categorized as human perception and be “understood” by computers. So all data is not only stored, but filed and well handled.

HTML describes documents and the links between them. RDF, by contrast, describes arbitrary things such as people, meetings, or airplane parts.

Some believe that emerging technologies such as the Semantic Web will transform the way the Web is used, and lead to new possibilities in artificial intelligence.

Web 2.0 exist today and had already shift the presentation of data on internet. Web 3.0 will not only make a hugh diffrence, but will change the whole methodology all togehter.
