Web 3.0 aka World Wide Database

Picture Holder1

The transition from the so called Web 1.0 to Web 2.0 would have seemed seamless if you have been a part of the World Wide Web since the late 90s. However, when you compare the functionalities between what you can do today and what you could do back then, the level of interactivity that exists today is a clear sign of how far the Web has come. With interaction becoming two-way, web sites that earlier stopped at providing information to the user is now increasingly dependent on the user to pool in content. Interdependency between the web site and the user is only going to grow in time and organizations that can capitalize on this will benefit the most from the Web's next leap, or rather Web 3.0.

Simply put, Web 3.0 is about imparting structure to the massive amounts of un-structured data, collected during Web 2.0, which is the first step towards true artificial intelligence. This will lead to the availability of high-quality customized information depending on the user’s ‘Web profile’.
Currently a search query depends solely on the key words that a user gives as input to the search engine. So if you want to know the latest news on Java the search engine gives you all results that contain the word. The first page of results would include news on the Indonesian islands as much as the popular programming language. But if your ‘Web Profile’ is brought into the picture, your search query would suddenly become context-oriented, based on your browsing history. Therefore, you would get to see results exactly based on what you are looking for, without having to shuffle your keywords.
What the above example indicates is that meta-data will define how the structuring of data occurs. Every piece of information on the Web will be referenced by these tags and coupling that with the context will result in useful information.
Google is Storing Away Your 'Web Profile' By Way of a Game
Companies such as Google are already getting their biggest client and customer – the user, to do this for them here , cleverly disguised it in the form of a game. This process enables computers to technically read web sites, check the relevance of the information and judge whether it is an appropriate match or not.
Contextual Search Results and the Semantic Web
As more of the Web transitions to this new form, you will be able to simply ask a a search engine -- “Where can I go for a weekend trip?” -- and based on your current location, time and other constraints you can expect reasonably accurate options listed in the search results. You would also get to see a list of hotels recommended by your trusted travel partner and links to book flights from your favorite airline. Although no one has quite figured out how to do it yet, this seems to be where we are heading. Welcome to the Semantic Web!
At the 2008 edition of the gold standard for India's software developer ecosystem, Great Indian Developer Summit, Jon Aizen had said that the semantic web is a decade old vision promoted by web visionaries like Sir Tim Berners Lee in which the web will become a set of semantically interconnected "databases" for programs to interact with, mash together and in general make sense of it all.
Tim-Berners Lee has been quoted as saying, "I have a dream for the Web to become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A ‘Semantic Web’, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The ‘intelligent agents’ people have touted for ages will finally materialize."
But as a bottom up technological adoption approach, it has failed miserably, and outside some research labs none of its icon technologies (e.g. RDF/OWL) have gained much traction. In fact, the web has continued to evolve as a messy technological babel tower.
So Jon, the co-founder and CTO of Dapper had advocated a new, top-down approach that transforms the existing web into a semantic web, where every site becomes a semantically aware API, using a combination of structure analysis algorithms and user generated effort. In his talk at GIDS 2008, Jon showcased the creation of semantic APIs from any site and presented the promise such approach holds for the advancement of fields such as semantic search.
HTML 5 WebSockets and API-Mashups
Context based searching is just one side to the web 3.0 story. It is being prophesied that Web 3.0 will see an abuse (in a good sense of course) of the API-mashup concept. With HTML 5 waiting on the border for wide scale usage and the kind of support it offers for application embedding within the browser, you should be able to intertwine your trusted chat application with Google Maps showing you the location of where exactly the other person at the end of line is sitting.
At the 2009 edition of Great Indian Developer Summit, the co-founder of Kaazing Corporation, Jonas Jacobi, spoke about how the HTML 5 specification is set to forever change the way in which we build applications for the Web. One innovation - WebSocket - in particular will enable full-duplex HTTP communication, and finally bring an end to the tired "click and wait" paradigm traditionally associated with the Web.
Prior to the introduction of WebSockets, bi-directional browser communication has been an elusive beast. Attempts to address this gap in the Internet architecture has circled around server-initiated message deliver or "push" techniques, commonly known as Comet or ReverseAjax, and typically achieved with an astonishing assortment of browser hacks. But, the emerging standards outlined in the HTML 5 specification, developers can now take advantage of a full-duplex communications channel that operates over a single socket. More specifically, WebSockets enable browsers to open a socket connection to any TCP-based back-end service (for example, JMS, JMX, IMAP, Jabber, and so on) allowing developers to easily create applications such as Web-based chat, and online trading, betting, and collaboration. Thus, with the help of WebSockets the browser now enjoys the first citizenry of network communications that has long been enjoyed by desktop applications.
As we get closer to such a system, questions on the morality of the Web will begin to rise.  If your web profile -- your avatar -- is stored on a server somewhere in a remote location, will it be accessible to others? Can somebody search for you? While speculators can answer these questions, we welcome you to the World Wide Database!
