Hi Ashley,

While datatyping is still a work in progress, it is anticipated
that you could express a base64 encoded literal in a form similar to
the following:

   <photograph rdf:type="http://www.w3.org/2001/XMLSchema#base64Binary">R0lGODlhEAAQAJ...</photograph>

Hopefully soon there will be a published WD from the RDF Core WG
which will discuss this kind of datatyped literal in detail.

Regards,

Patrick
