Bing, Google and Yahoo! have announced Schema.org
Here is the info
Today we’re announcing schema.org, a new initiative from Yahoo!, Bing, and Google, to create and support a common set of schemas for structured data markup on web pages. With schema.org, webmasters and developers can learn about structured data and improve how their sites appear in search results on Bing, Google, and Yahoo!. Information and tips are available on schema.org, a one-stop resource for webmasters looking to add markup to make their pages better understood by search engines.
What is Schema.org?
This site provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognized by major search providers. Search engines including Bing, Google and Yahoo! rely on this markup to improve the display of search results, making it easier for people to find the right web pages.
Many sites are generated from structured data, which is often stored in databases. When this data is formatted into HTML, it becomes very difficult to recover the original structured data. Many applications, especially search engines, can benefit greatly from direct access to this structured data. On-page markup enables search engines to understand the information on web pages and provide richer search results in order to make it easier for users to find relevant information on the web. Markup can also enable new tools and applications that make use of the structure.
A shared markup vocabulary makes easier for webmasters to decide on a markup schema and get the maximum benefit for their efforts. So, in the spirit of sitemaps.org, Bing, Google and Yahoo! have come together to provide a shared collection of schemas that webmasters can use.
