What is Microformats?
This is one way of enabling web as semantic. The current web markups are very keen on displaying content on the browsers. As an user we know what is on the page, as a system it just displays it. However, how can develop a system to organize, collect and manage the contents from web pages? Previously, it is impossible. There are millions of terra bytes of content exist in the web. But now, Semantic Web which was initiated by Tim Berner Lee helps us to make this possible.
Microformats are one such standard which reuse existing markup elements to convey semantic of the data. For example, the following snippet shows a hCard telephone contact details.
