Web 3.0 is about creating a more “intelligent” Web.  It is a way for us to tell computers  how to take the enormous amount of data that already exists and each of us generate on a daily basis and deliver it to us in a more meaningful and usable way.  Web 3.0 promises to take away the repetitive tasks that machines can do at a fraction of the speed, and enable people to do what is uniquely human… to simplify and humanize our online experience.

Web 3.0 is a collection of technologies that consist of the semantic web, linked data, natural language processing (NLP), artificial intelligence, mashups, & APIs.  Regardless of the specific technology the core idea behind Web 3.0 is that when your information is organized you can extract much more meaningful and actionable insight from that information.

There are few challanges of web 3.0

* Creating structuring data – unfortunately, the first step in making Web 3.0 a reality is in the web developer hands. Web developers have to start using RDFa and Microformats to “mark up human-readable data with machine-readable indicators for browsers and other programs to interpret” (get more info about the differences between RDFa and microformats ). During his presentation at the conference, Aza Raskin, head of User experience of Mozilla Labs, stated that “we have the chicken and the egg problem”…we know RDFa & microformats are good but no one uses them because there are very few use cases right now for the general public to widely adapt the practice and use cases can’t be created until the public starts to mark up their data.
* Sharing Data across the Web – Another challenge that we are facing is convincing organizations to share their data so it can be re-used in a more functional way.  In the Web 3.0 world, content developers have to get over the notion that users have to come to their website to get the information they need.
* User Interfaces – Deciding the best way to display the massive amounts of data in a usable and meaningful way will be challenge for all of us and we will all have to experiment with what works best.  One of the ways to solve this problem is to open your application code to users via an API and let the users decide how they want to consume your data by developing their own interfaces for the devices of their choice.
* Indexing and Scaling all the data – The semantic web will not happen any time in the near future because of scale…the technology is just not there and right now it’s impossible to index all of the content from all of the people creating content in the world.

Web 3.0 is still in it’s infancy and we still have a lot of challenges that need to be solved.  According to Peter Sweeney, Founder & CTO of Primal fusion, in order to push Web 3.0 through we have to have another “industrial revolution”….”In 1996 Web 1.0 was just about getting us online. Web 2.0 was revolutionary. Getting consumers involved in content was absurd until companies started doing it”.
