Abstract
This paper presents a novel programming language called LOC (Logical Objects with Constraints), which combines logic programming and object-oriented programming paradigms. In LOC, logical objects are viewed as abstractions with state, constraints, behaviors and inheritance. It therefore supports such notions as inheritance, modularity and reusability, which have turned out to be extremely useful for large scale software systems. The operational interpretation defined in the style of natural semantics is simple and clear. The transformation of LOC into Prolog is also explored to indirectly illustrate the descriptive semantics.

Linear objects: Logical processes with built-in inheritance
AbstractWe present a new framework for amalgamating two successful programming paradigms: logic programming and object-oriented programming. From the former, we keep the delarative reading of programs. From the latter, we select two crucial notions: (i) ...
A logical theory of concurrent objects
A new theory of concurrent objects is presented. The theory has the important advantage of being based directly on a logic called rewriting logic in which concurrent object-oriented computation exactly corresponds to logical deduction. This deduction is ...
