Why am I getting the error "Required Property Missing" when integrating Facebook Open Graph?
I am attempting to integrate Facebook open graph into my site but I ran it through the URL Linter (https://developers.facebook.com/tools/lint) and I get the error: "Required Property Missing, og:title is required"
I'm concerned it's because my html is not valid or is missing something:

You are defining the homepage as the url to use with og:url, when you should be using the current URL or leave it out completely.
og:url - The canonical URL of your object that will be used as its permanent ID in the graph, e.g., http://www.imdb.com/title/tt0117500/.
