A general comment, microdata appears to be incredibly verbose for
authors when using multiple vocabularies to describe things, the example
at http://dev.w3.org/html5/md/#examples is almost painful to read, let
alone write.
Is there no way to reduce the repetition of long URIs for properties and
types as illustrated by the Turtle equivalent in the referred to
example? Does HTML or Microdata cater for this in any way?
When we did the usability studies for this we found that in practice (and
much to my surprise) the verbosity had no impact on the usability of the
language, so we didn't do anything to reduce it.
When you did that usability study, if I remember correctly, there was
only 6 test subjects, all Google employees, and I believe volunteers.
That does not make a study you can extrapolate from.
Furthermore, in practice, most use cases for microdata don't involve
multiple vocabularies but a single vocabulary explicitly named using
itemtype="", for which the vocabulary's short names are used.
Actually, I don't think there is any "practice". I've not seen microdata
used in the wild. Not to say there isn't, but I've not seen it.
