Is it possible to get rich Spotlight results for local items? I want to show the "play" button for an audio file locally stored on the device in the search results.
The Spotlight session from the WWDC lists
<div itemscope itemtype=
"http://schema.org/AudioObject">
<meta itemprop="contentUrl" content="http://abc.com/x.m4a" />
</div>
or
<meta property="og:audio" content="http://example.com/music.m4a">
for this. How would I use this? Am I supposed to be able to add that (using the appropriate local file URL) to the HTMLContentData attribute? (Hint: that didn't work for me)
