Editing Prolog (section)

=== Object-orientation ===
[[Flora-2]] is an object-oriented knowledge representation and reasoning system based on [[F-logic]] and incorporates [[HiLog]], [[Transaction logic]], and [[defeasible reasoning]].

[[Logtalk]] is an object-oriented logic programming language that can use most Prolog implementations as a back-end compiler. As a multi-paradigm language, it includes support for both prototypes and classes.

[[Oblog]] is a small, portable, object-oriented extension to Prolog by Margaret McDougall of EdCAAD, University of Edinburgh.

[[Objlog]] was a frame-based language combining objects and Prolog II from CNRS, Marseille, France.

[[Prolog++]] was developed by [[Logic Programming Associates]] and first released in 1989 for MS-DOS PCs. Support for other platforms was added, and a second version was released in 1995. A book about Prolog++ by Chris Moss was published by Addison-Wesley in 1994.

[[Visual Prolog]] is a multi-paradigm language with interfaces, classes, implementations and object expressions.
