I'm going over Facebook's Open Graph API. All of it seems simple and is explained well except for the fb:admins meta tag. What is this for?
For example:
<meta property="fb:admins" content="USER_ID"/>
Facebook says this: A comma-separated list of either Facebook user IDs or a Facebook Platform application ID that administers this page. It is valid to include both fb:admins and fb:app_id on your page. I'm just not sure what this is.
I guess it is the combination of the ids that is tripping me up.
