Open source object-oriented logic programming language

Logtalk is an object-oriented logic programming language that extends and leverages the Prolog language with a feature set suitable for programming in the large. Written in highly portable code, it can use most modern Prolog implementations as a back-end compiler. As a multi-paradigm language, it includes support for both prototypes and classes, protocols (interfaces), categories (components), event-driven programming, and high-level multi-threading programming. Its distribution includes full documentation, portable libraries, a comprehensive set of portable developer tools, and a large number of programming examples to help get you started.
