Starting with teaching herself HTML in 1996 (and dreaming in it for a while), Denise R. Jacobs has worked at creating and maintaining websites, web application localization, web project management, and teaching web design/development since then.
Currently, Denise is a Web Solutions Consultant with her company PapillonEffect.com in Miami, Florida. She helps individuals and businesses increase their web knowledge, transform their web presence, and bring their websites into the 21st century with standards-based markup, web 2.0 tools, and the use of Social Media.
Microformats are small patterns of HTML to represent commonly published things like people, events, blog posts, reviews and tags in web pages.
Great. So what good does that do?
Microformats are a way of adding simple markup to human-readable data items such as events, contact details or locations, on web pages, so that the information in them can be extracted by software and indexed, searched for, saved, cross-referenced or combined.
In other words…
Microformats capitalize on the way people already work with and use the web, and add an additional layer of information that enhances functionality and use of the content on your pages.
Microformats are based on clean, semantic (X)HTML (aka POSH). If you use this already, you are very close to using microformats, and you won't have to do much additional work to implement them on your site.
Microformats add information to a web page using mostly the class attribute (although sometimes the id, title, rel or rev attributes too). The class names are semantically rich and describe the data they encapsulate.
