A few days ago Facebook announced their new Open Graph Protocol. It’s basically a way for people to interact with pages on the internet (in theory pages representing real world items, but it will be hard to moderate) in basically the same way as they do with existing Facebook pages.
For a page to be eligible all you need to do is add a few meta tags to it specifying it’s name and type (film, book, actor, product, game etc.). To actually do anything useful, you then add a Facebook “like” button. Once some people have liked it, it appears in their Facebook news feed like any other item (with the data you added in the meta tags). One of the optional meta tags you can add specifies user IDs of Facebook users who can administrate the page. If you do, you can get access to the same sort of admin page you get with any traditional Facebook page.
Conveniently I just developed a use for this sort of thing so I added support to my blog. A few edits to the theme and cunning use of WordPress’s custom fields and now any page or post on my site can support Open Graph. Currently the only support is on the Gravitas page.
