Macro-supported DSLs for schema bindings

We've recently started using the W3C's banana-rdf library at MITH, and it's allowing us to make a lot of our code for working with RDF graphs both simpler and less tightly coupled to a specific RDF store. It's a young library, but also very clever and well-designed, and it does an excellent job of exploiting advanced features of the Scala language to make its users' lives easier. Alexandre Bertails and his collaborators deserve a lot of credit for what they've accomplished in just a little over a year.

One of the least pleasant aspects of working with any RDF library is writing bindings for particular vocabularies. For example, if we wanted to use the Open Archives Initiative's Object Reuse and Exchange vocabulary in our banana-rdf application, we'd need to write something like the following:
