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 .
