Is there any way to validate the Open Graph protocol meta tags for Facebook integration?

Question

Is there any way to validate the Facebook Open Graph protocol meta tags in the head section of my website? Code below.

<meta property="og:title" content="my content" />
<meta property="og:type" content="company" />
<meta property="og:url" content="http://mycompany.com/" />
<meta property="og:image" content="http://mycompany.com/image.png" />
<meta property="og:site_name" content="my site name" />
<meta property="fb:admins" content="my_id" />
<meta property="og:description" content="my description" />

-edit- I mean validating the html. Sorry for the confusion! Right now my site isn't valid because of these tags.

Solution 1

Facebook URL Linter?

EDIT: Ah, then refer to this question.

Solution 2

... open graph meta tags will only validate in HTML5....
