Is meta fb: page_id still on the website?

Question

I am using Open Graph on a website.

As mentioned in the Facebook documentation, this allowed a meta to be placed like this:

meta property = "fb: page_id" content = "your_page_id"

But the Facebook debugging tool showed an error :

Extraneous property: objects of this type do not allow named fb: page_id properties.

Other websites seem to have the same error as Mashable.com

In the other hand, on the other documentation page , the page administration seems to work only with fb: admins and / or fb: app_id. But no mention of fb: page_id.

So what are the fb: page_id metadata states on the website?

Answer 1

The behavior you describe seems to be a mistake. The question was sent to Facebook and accepted:

http://developers.facebook.com/bugs/144705805635591/?browse=search_4f0323eb790c29273088132 .

Now it is resolved.

Answer 2

I have no answer for this, but I am also looking for it. OGP was not required to function, but was to understand the pages. Lately, I can't see fb: page_id being mentioned more in ogp.me or facbook docs.
