just as a heads in case some try to look for this in their browser: the
microdata API is not implemented by any of the popular browsers (at least
I'm not aware of any). It was part of WebKit and Blink for a few months but
was removed. This post
<http://manu.sporny.org/2013/microdata-downward-spiral/> has more details
and links (while the facts in this post are accurate, be warned that it is
biased towards RDFa).
