Facebook Debugger can't fetch open graph metadata

I have a simple web page with includes a javascript redirect and has a few opengraph metadata.

The page parses correctly on OpenGraph.in ( http://bit.ly/pMehOj ) and even validat开发者_StackOverflowes correctly on the w3c validator

But it miserably fails to parse with the Facebook Debugger ( http://bit.ly/nyGWlM )..

What could be wrong?

You must have link to the open graph protocol

Add xmlns:og="http://ogp.me/ns#" in your html declaration as below :

html lang="en" xmlns:og="http://ogp.me/ns#"
