The standard object system for PLT Scheme is known as class.ss, and is specified in PLT MzLib: Libraries Manual (Online Documentation).

An alternative object system for PLT Scheme is part of Swindle by EliBarzilay?, and is similar to Common Lisp's CLOS. It can be obtained from http://www.barzilay.org/Swindle/ , and is also now available in PLT CVS?. Dartmouth 2004 CS18 class notes provide a tutorial on a modified Swindle. See also Joe Marshall's A Warp Speed Introduction to CLOS and CLOS (Swindle) Cheat Sheet.

Due to the flexible nature of Scheme, there are many other ways to do object-oriented programming. For example, class notes from Georgia Tech 2002 CS1321 (Part I and Part II) show another way.

And there's also ROOS, an other example of OO in scheme. This one resembles Perl's implementation of OO a lot.

A small sample of the object systems available for scheme. They mostly contain examples of use. (hence the link from the cookbook)

Class object systems

• ROOS
• TinyCLOS - Developed at Xerox Parc by Gregor Kiczales.
• Meroon CLOS-like generic functions.
• Swindle - some MOP extensions
• Bigloo object system - does not include any meta object protocol.

Self/Prototype object systems

• Prometheus Object System, a prototype-based object system inspired by Self
• Protobj: Prototype-Delegation Object Model
• ScmObj
• Purely-functional Object-Oriented System
