Abstract
Order-sorted conditional equational logic is proposed as a framework for the specification and verification of active objects. One single algebra can be used to cover both data and process aspects of active objects, with pure data objects, e.g. integer numbers, on one end of the spectrum, and pure behaviour, e.g. automata, on the other. The order-sorted approach is presented in a categorial setting which provides a formalization of object interaction and reification through suitable morphisms in a way such that reification distributes over parallel composition.
