Just a couple of links that deal with the usage or testing of structured data.

Structured data is not yet relevant for content rankings, but that might change in the future (Hangout).

“Structured data markup” is a standard way to annotate your content so machines can understand and categorize it. Proper usage elevates the way data is displayed on Google Search, Facebook, Twitter, Pinterest and many others, when one of your content links is posted there.

INTEGRATION

The Knowledge Graph and You

TESTING

Really looking forward to the JSON-LD integration :)
