class Chunk include DataMapper::Resource property :id, Serial # auto-increment integer key has n, :contexts, :through => Resource end class Context include DataMapper::Resource property :id, Serial # auto-increment integer key property :filename, String # Context may represent a text-file has n, :chunks, :through => Resource end
