METAL: An Object Oriented Metalogic Language

We describe an approach to object oriented logic programming. Objects are represented as theories and executing a method of an object amounts to querying the object’s theory. Classes contribute rules to the theory of each instance. The local state of an object comprises a collection of unit clauses and the state of an object is encapsulated. Inheritance combines theories to form the theory for a class. We describe the features of a prototype exploring this approach and we develop part of a simplified metaobject protocol for the
