when you talk about any kind of information system providing services, 
an important question always is what kind of agent is using it. in 
traditional hypermedia, humans are making the interaction choices, so 
human-readable labels suffice. in REST as a SOA approach, it's machines, 
so we need a little different approach. in this case, the affordances 
need to be more user-friendly from a machine-point of view, mike and i 
have talked quite a bit about "API UX", i.e. how easy is it for you as a 
developer to conveniently consume a service. RESTful design these days 
has mostly come to the conclusion that any RESTful service needs a 
description that clearly specifies both data models and interaction 
models. there are different ways how you can do that (and many different 
frameworks have been proposed), but no matter what your preference is, 
you somewhere somehow have to address those two issues. RDF currently 
gives you a framework for issue #1, and issue #2 is left an exercise for 
groups such as us. we can do it informally or formally, and we can try 
to do it so that it's reusable or not, but no matter how we approach the 
problem, we have to solve it.
