>                 URL: https://issues.apache.org/jira/browse/TIKA-728
>             Project: Tika
>          Issue Type: Improvement

> Open Graph <meta> tags currently get stripped out, and also aren't put into the metadata map.
> The reason why is that Open Graph uses RDFa:
> http://stackoverflow.com/questions/2704942/html-validation-error-for-property-attribute/2705090#2705090
> Since <meta property="xxx" content="yyy" /> isn't valid for XHTML 1.0, these tags can't be emitted.
> We could take a tag like:
> <meta property="og:url" content="http://www.imdb.com/title/tt0117500/" />
> and put it into the metadata map as "og:url" => "http://www.imdb.com/title/tt0117500/"
