Aye, posted.
Initially thought for html representation of metadata, is to put it in attribute. But then I noticed that in resumes, people would type address and contact details in the same format. So I switch to div tags, but that seems rather limiting.
I think the best option for representing metadata is http://www.w3schools.com/tags/tag_dl.asp . It was recommended in html5 doctor. Incidentally there is a talk on description list here in this site e.g.
<h1>Authorship</h1>
<dl class="metadata authorship" >
<dt>Authors:</dt>
<dd>Remy Sharp</dd>
<dd>Rich Clark</dd>
<dt>Editor:</dt>
<dd>Brandan Lennox</dd>
<dt>Category:</dt>
