Structured Data Dashboard on Google Webmaster Tools

Google announced another cool data feature on Google Webmaster Tools - the Structured Data Dashboard! This new tool, which is under the "Optimization" section of Google Webmaster Tools, breaks out the structured data Google finds on your web site at three levels:

• Site-level view: the Structured Data Dashboard, which is under Optimization, aggregates this data (by root item type and vocabulary schema). Root item type means an item that is not an attribute of another on the same page.
• Item type-level view: Google parses and stores a fixed number of pages for each site and item type. They are stored in decreasing order by the time in which they were crawled.
• Page-level view: Google has a details page showing all attributes of every item type on the given page (as well as a link to the Rich Snippet testing tool for the page in question).
