Despite the plethora of acronyms that confuse - and an aweful economy, the reality is that Web 3.0 has arrived.
- Web 1.0 used servers to host pages and intelligence. Browser software had little intelligence. Users benefit from easy access.
- Web 2.0 transferred knowledge from servers to intelligent browsers that managed the presentation. Acronyms like AJAX, JSON, XML, and others described data transfer and control protocols. Users benefit from more interesting and varied user experiences.
- Web 3.0 allows integration of data from many servers to the intelligent browser. Users will begin to see new services - that are no longer restricted to the content of one server provider.
- Yahoo, Google, and Microsoft have opened their search robots for use by applications. This includes the treasure trove of pages, images, videos, music, and other data that are scanned by their army of robots and stored in their databases.
- Microformats define information about people, companies, events, reviews, locations, and other structured data. Data is no longer locked into a database. It's available as data hidden in pages that robots can understand, extract, and process. Semantic web - it's the intelligent inference to deliver more value to users at websites.
- Opensocial attempts to open the information about people, friends, and photos - locked behind garden-wall environments like FriendFeed, Myspace, and LinkedIn - available for use on any website.
- Other projects attempt to open databases of product information - stored at Amazon, eBay, and other locations - for use in web 3.0 websites.
- Cloud computing offers services such that site creators no longer need computers as servers, databases to hold content, and sites to hold pages. Services such as Youtube host video, FlickR or Picasa hosts images, and Blogger or Wordpress hosts pages. All the parts needed for a web 3.0 website reside with various public providers. RSS feeds, a simplified web service, are the public transport for moving data from one server to the browser.
