Web 3.0, or the Semantic WebThese concepts are still taking shape, although there are already some applications trying to gain momentum in this space known as the Semantic Web.
Web 3.0 Definition (from Wikipedia): Web 3.0 is one of the terms used to describe the evolutionary stage of the Web that follows Web 2.0.
Given that technical and social possibilities identified in this latter
term are yet to be fully realised the nature of defining Web 3.0 is
highly speculative. In general it refers to aspects of the internet
which, though potentially possible, are not technically or practically
feasible at this time.
Semantic Web definition (from Wikipedia): 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. It derives from World Wide Web Consortium director Sir Tim Berners-Lee's vision of the Web as a universal medium for data, information, and knowledge exchange.
Nova Spivack defines Web 3.0 as: "Web 3.0, in my opinion is best defined as the third-decade of the
Web (2010 - 2020), during which time several key technologies will
become widely used. Chief among them will be RDF and the technologies
of the emerging Semantic Web. While Web 3.0 is not synonymous with the
Semantic Web (there will be several other important technology shifts
in that period), it will be largely characterized by semantics in
general.
Web 3.0 is an era in which we will upgrade the back-end of the Web,
after a decade of focus on the front-end (Web 2.0 has mainly been about
AJAX, tagging, and other front-end user-experience innovations.) Web
3.0 is already starting to emerge in startups such as my own Radar Networks, but will really become mainstream around 2010.
Why is defining Web 3.0 as a decade better than just about any other
possible definition of the term? Well for one thing, it can't easily be
co-opted by any company or individual for their own commercial ends.
It's also a completely unambiguous definition -- it refers to a
particular time period and everything that happens in Web technology
during that period. This would end the debate about what the term means
and move it to something more useful to discuss: What technologies and
trends will actually become important in the coming decade of the Web?"
