Schema.org is a semantic markup format for online data. The format was published by Google, Bing and Yahoo! search engines in summer 2011.
The purpose of semantic markup is to make the internet more structured and understandable for search engines and special programs that extract and process information in order to better display it in search results.
You can mark up documents using special attributes that are entered directly in HTML code. You don't need to create any separate export files.
Why use microformats
You can use semantic markup to improve your site's snippets in the search results.
Compare the snippets for a page from a Yandex.Dictionaries partner site. One snippet is based on semantic markup and the other one isn't.

The standard provides a set of classes describing a variety of entities and their properties. There are already several hundred of them. The standard is constantly being improved, with adding new properties and extending the existing ones.
Basic markup principles
Schema.org markup is carried out in two steps:
First you wrap a certain type in a container and specify the markup schema:
<div itemscope itemtype="http://schema.org/Organization" > ... </div>
Then you enter the appropriate values for each markup attribute:
<span itemprop="streetAddress">Lev Tolstoy, 16</span>
Document without markup
