OpenStep

An object-oriented development environment from Apple, which runs on Windows, Sun and HP machines. OpenStep was originally developed by NeXT Computer as part of its NextStep operating system. OpenStep was incorporated into Rhapsody and later Mac OS X as the Yellow Box programming interface (Cocoa). See NeXT, Rhapsody and Cocoa.


(operating system)OpenStep - An object-oriented application programming interface (API) derived from NEXTSTEP and proposed as an open standard by NeXT in 1994.

OpenStep is the specification of the object kits of NEXTSTEP. OPENSTEP/Mach was an implementation of this specification. The original, OPENSTEP version 4.0, and really was NEXTSTEP 4. Rhapsody was the codename for Apple's Mac OS X Server, which is really NEXTSTEP 5 (it calls itself "kernel 5.3" at boot time).

OpenStep was designed to be implemented independently of the computer's operating system, hardware, and user interface. The API for Rhapsody will be a superset of OpenStep's.

When the OpenStep API is implemented for a specific platform and made into a product, it is written in uppercase, e.g. OPENSTEP Developer 4.2 for Mach, or OPENSTEP Enterprise for Windows NT and Windows 95. Versions of OPENSTEP exist for Windows 95/NT, Solaris, HP/UX, and Mach.
