I used the FB page linter to verify that all the meta information I\'m using is correct. According to the graph url, my page id is 157797447612809, yet when I try to publish a
The Geopoint object is described here:
https://developers.dev.facebook.com/docs/opengraph/complextypes/#geopoint
Example:
<meta property="your-og-app:location:latitude" content="37.416382">
<meta property="your-og-app:location:longitude" content="-122.152659">
<meta property="your-og-app:location:altitude" content="42">
I have spent too many hours on this but it doesn't seem possible. Then I came accross with this answer. I think this feature is currently open only to Foursquare. Facebook API docs doesn't have anything related to this.
I think you'd need to add at least the location related tags e.g. og:longitude & og:latitude.
See this graph output for a page that has these og tags and checkins.

BTW: I hope you get the irony of this example 8)
I'm also not sure if you can checkin to a og:type=food page. It may have to be one of the places types e.g. landmark - see types info on the OpenGraph page. However the example above is for og:type=company so you'd need to test the different types to see.
Since there is absolutely no documentation by Facebook on this matter, I solved this by looking at what foursquare has done and a lot of trial and error.
When defining your open graph object within facebook, you must add a property of type GeoPoint. I called mine location. Define in the object page meta like this:
<meta property="mytestapp:location:latitude" content="37.791" />
<meta property="mytestapp:location:longitude" content="-122.395" />
Now when you debug/lint this object it register as a place, just like the foursquare HQ. You can check in and create map views for actions that include this object.
