It’s hardly new – not in web terms. Microformats are a method of marking-up types of content to be easily lifted or shared with other websites or applications. For instance, the name and address of your company can have certain class names attributed to your HTML elements. These class-names can then be read by a web app, which will allow a site visitor to insert those details directly into your address book with the click of a link. Microformats are not that difficult to apply – in most cases it’s just a slight modification of your HTML classes.
