Also, one might prefer RDFa or GRDDL to achieve similar goals.

I'm not expert enough to recommend one over the other, however GRDDL
does seem to be dynamic enough that it might be a low-hanging fruit to
grab for Open Guides.

Of course Open Guides already outputs actual RDF/XML, so some might
argue this whole exercise is somewhat redundant.
