The language designer typically has one particular application domain in mind: as subsequent types of applications are tried, what had originally been US&II j2urure.y become undesirable limitations, and the language is overhauled or scrapped. One remedy to this bleak cycle might be to construct a representational scheme whose domain is the field of representational languages itself. Toward this end, we designed and implemented RLL, a frame-based Representation Languange Language. The components of representation languages in general (such ti slots and inheritance mechanisms) and of RLL itself are encoded declaratively as frames. Modifvinn these frames can change the of the RLL environment. semantics of RLL, by altering the 1.
