[jira] [Commented] (TIKA-728) Return RDFa meta tags via Metadata

["Ken Krugler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13113472#comment-13113472 ] 

Ken Krugler commented on TIKA-728:
----------------------------------

That's what I was afraid of :)

My head starts to hurt when I have to deal with namespaces and RDF.

So I think I'll just patch my local copy to do the Q&D thing, and wait for someone with more XML/RDF-fu to deal with it properly.

> 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/"
