Can you describe the user experience in more specific terms? Perhaps an
end-to-end scenario would help clarify what you want.

RDF is just a data model and I think it should be generic enough to
model what you want. It might require more RDF statements than you
think, and obviously the child should not be seeing the raw data as-is.

The Operator extension for Firefox can read microformats:
http://labs.mozilla.com/2006/12/introducing-operator
https://addons.mozilla.org/en-US/firefox/addon/4106
and RDFa and eRDF can be considered the Semantic Web versions of
microformats:
http://www.w3.org/TR/xhtml-rdfa-primer/
http://research.talis.com/2005/erdf/wiki/Main/RdfInHtml
(although Piggy Bank reads none of these three).
