Not sure how useful this might be around microformats, but one thing I
think helped with Atom design was looking at it in entity-relationship
terms. RDF and UML are formal ways, but an informal X and Z are
things, Y is their relationship kind of model may be enough to see
where vocabulary interaction potentially might (or might not) work.

In Atom, here and there you have things like RDF's bnodes, e.g.

<feed>
   <author>
      <name>Norman Walsh</name>
   </author>
</feed>

Which can be read as:

feed                     (entity)
-author-                (relationship)
[somebody]          (entity)
-name-                 (relationship)
"Norman Walsh"   (entity)

things are going astray if you have unintermediated (entity)(entity)
or (relationship)(relationship).

Next up the direction of relationships need considering - TimBl had a
good post on this (talking about RDF, but I think it generalises) :
