OpenStep – an object-oriented operating system that uses any modern operating system as its core. Mainly created by NeXT. NeXT Computer Inc, and Sun Microsystems Inc. teamed up in late 1993 to push a free object layer API based on the NeXTSTEP object system. This agreement evolved into the OpenStep specification which was published by NeXT in a first draft back in summer 1994.
There is a distinction between OpenStep, which is an API specification, and OPENSTEP (capitalized) which is a specific implementation of OpenStep developed by NeXT. Although it was originally created on a Unix-based Mach kernel (just like the NeXTSTEP core), OPENSTEP versions were also available on Solaris and Microsoft Windows NT. Therefore, OPENSTEP libraries (which were supplied with the OPENSTEP system) are actually a subset of the original OpenStep specification.
