I dunno, REST maps to CRUD pretty well -- but its pretty limited when you think of it as restricted to CRUD operations against the equivalent of base tables in whatever your datastore of choice is -- its more like CRUD operations against views with arbitrarily complex rules mapping operations on the views to operations against base tables...
