Microformats has only become a popular data format that helps to structure Web content recently. For this newly open data format that was supported by some established companies such as Microsoft, Yahoo!, Mozilla, etc. the future is bright for them. It is designed for humans first and machines second, and mostly to be used in structuring Web content such as contact information or events.
There is a little unknown search engine called Virel.de that aimed to enable your contact information, they called it hCard visible on the Web. Virel is a search engine that is available in German and English. Users can search all the available contacts or events it crawled on the Web and stored in its database. All the contacts or events can be searched with a simple keyword you type in its search bar. For example, I typed in “pub,” it will return all the results relevant to my keyword from some well-known Web services such as Mixx, Technorati, and etc. (See below picture) The results return can either be saved to my email client using the vCard format, or I also can view it in a picture format, i.e. its DataMatrix.
Meanwhile, you also can create your own microformats by submitting your personal particular using the hCard creator form prepared by Virel or this Microformats Organization. Upon you completely submitted your details, you can use the code it generate and embed it to your Web site and make your microformats accessible to the public.
