f8

We shared an update last week about the products launched at f8 and that over 50,000 websites have already implemented the new social plugins to become more personalized. We created the Open Graph protocol in support of social plugins as part of our efforts to help realize the vision of the Open Graph. Any website can implement the Open Graph protocol. It allows any web page to become a rich object in any social graph, making it easy to find what people are liking across the Web -- from a movie to a blog. To start integrating the Open Graph protocol into your Web pages, read our documentation .

After f8: Implementing the Open Graph Protocol around the Web -

The Open Graph Protocol Design Decisions

The Open Graph Protocol

The Open Graph protocol enables any web page to become a rich object in a social graph. For instance, this is used on Facebook to allow any web page to have the same functionality as any other object on Facebook. While many different technologies and schemas exist and could be combined together, there isn't a single technology which provides enough information to richly represent any web page within the social graph. The Open Graph protocol builds on these existing technologies and gives developers one thing to implement. Developer simplicity is a key goal of the Open Graph protocol which has informed many of the technical design decisions . To turn your web pages into graph objects, you need to add basic metadata to your page.
