I share your suspicion/hope that bidirectionality is feasible. The
current mapping, as you say, doesn't feel quite right. Now that we have
QName'd 'roles' for XLink link types, I'm wondering whether we could
have a simple interpretation of typed links that (in the basic case) used the
Qualified-named 'role' as the RDF property type connecting the 'from'
and 'to' resources. Something like this raises prospect that we could
mine a web of XLink documents for RDF assertions that could be slurped
into an aggregated RDF database...
