Marking up structured data - Webmasters/Site owners Help. Rich snippets (microdata, microformats, RDFa, and Data Highlighter) Snippets—the few lines of text that appear under every search result—are designed to give users a sense for what’s on the page and why it’s relevant to their query. If Google understands the content on your pages, we can create rich snippets—detailed information intended to help users with specific queries. For example, the snippet for a restaurant might show the average review and price range; the snippet for a recipe page might show the total preparation time, a photo, and the recipe’s review rating; and the snippet for a music album could list songs along with a link to play each song. These rich snippets help users recognize when your site is relevant to their search, and may result in more clicks to your pages.
Three steps to rich snippets: 1. Google suggests using microdata, but any of the three formats below are acceptable. 2. Google supports rich snippets for these content types: 3. That’s it! Use HTML markup if... Value Class Pattern. The value-class-pattern solves two of the three most challenging issues that microformats have encountered in their entire history: accessibility and localization. After many long months of focused iterating (repeatedly researching, brainstorming, testing, documenting) led by Ben Ward, the value-class-pattern alpha draft is ready to use and support. Publish and implement Several publishers have already started using the value-class-pattern, including this blog, and some implementations have already started supporting it as well. Everyone who publishes content marked up with microformats or develops microformats implementations such as parsers and authoring tools should take a close look at supporting the value-class-pattern in the content they are publishing and the tools they are implementing.
If and when you encounter any issues or have feedback regarding the value-class-pattern, please add them to the value-class-pattern-issues and value-class-pattern-feedback pages respectively.

This February, Google released its Social Graph API, which allows developers to give users the option to easily find data on their social connections around the web. Google itself, however, hasn't really implemented any of this technology yet. Starting today, however, it seems Google is starting to surface some of this information from your Social Graph in your Google Profile, which might be a first sign that Google is planning to do more with these profiles than it has done so far.
Google has also started implementing the hCard microformat there. The first person to noticed this was Chris Messina. Google's Social Graph API harnesses this information from XFN and FOAF data that is published by Wordpress, Twitter, or any other social network or blog that wants to implement these open standards. hCard Also, as Chris Messina points out in this video, the profiles now also support the hCard microformat, which makes importing them into other products a lot easier.
