SunSoft, HP, IBM and USL announced CDE in June 1993 as a joint development within the Common Open Software Environment ( COSE ) initiative.

In March 1994 CDE became the responsibility of the " new OSF ", a merger of the Open Software Foundation and Unix International ;

" Stallman states that while the term " Free Software " can lead to two different interpretations, one of them is consistent with FSF definition of Free Software so there is at least some chance that it could be understood properly, unlike the term " Open Source ".

Some free software advocates use the term Free and Open Source Software ( FOSS ) as an inclusive compromise, drawing on both philosophies to bring both free software advocates and open source software advocates together to work on projects with more cohesion.

Despite the fundamental philosophical differences between the free software movement and the open source movement, the official definitions of free software by the Free Software Foundation and of open source software by the Open Source Initiative basically refer to the same software licences, with a few minor exceptions.

* Why “ Open Source ” misses the point of Free Software, by Richard Stallman

According to Eric S. Raymond, the Open source and Free Software hacker subculture developed in the 1960s among ‘ academic hackers ’ working on early minicomputers in computer science environments in the United States.

People primarily known for their contributions to the consciousness of the programmer subculture of hackers include Richard Stallman, the founder of the free software movement and the GNU project, president of the Free Software Foundation and author of the famous Emacs text editor as well as the GNU Compiler Collection ( GCC ), and Eric S. Raymond, one of the founders of the Open Source Initiative and writer of the famous text The Cathedral and the Bazaar and many other essays, maintainer of the Jargon File ( which was previously maintained by Guy L. Steele, Jr .).

KornShell is available as part of the AT & T Software Technology ( AST ) Open Source Software Collection.

Mach received a major boost in visibility when the Open Software Foundation ( OSF ) announced they would be hosting future versions of OSF / 1 on Mach 2. 5, and were investigating Mach 3 as well.

The OpenContent website once defined OpenContent as ' freely available for modification, use and redistribution under a license similar to those used by the Open Source / Free Software community '.

For similar reasons, the Free Software Foundation describes the Open Content License as a non-free documentation license and the Copyfree Initiative has rejected it for certification as a copyfree license.

Despite the fundamental philosophical differences between the free software movement and the open source movement, the official definitions of free software by the Free Software Foundation and of open source software by the Open Source Initiative basically refer to the same software licenses, with a few minor exceptions.

Although born from the same history of Unix, Internet free software, and the hacker culture as the free software movement launched by Richard Stallman and his Free Software Foundation, the Open Source Initiative was formed and chose the term open source, in Michael Tiemann's words, to " dump the moralizing and confrontational attitude that had been associated with ' free software ' in the past and sell the idea strictly on the same pragmatic, business-case grounds that had motivated Netscape.

The group adopted the Open Source Definition for open-source software, based on the Debian Free Software Guidelines.

He then moved to the Open Source Development Labs, which has since merged with the Free Standards Group to become the Linux Foundation, under whose auspices he continues to work.

Some of these organizations and projects include The Open Textbook Project, Connexions, The Saylor Foundation Open Textbook Challenge and Wikibooks

Unix International ( UI ) merged into Open Software Foundation ( OSF ) in 1994 only to merge with X / Open to form The Open Group in 1996.

In January 1997, the X Consortium passed stewardship of X to The Open Group, a vendor group formed in early 1996 by the merger of the Open Software Foundation and X / Open.

In early 2004, various people from X. Org and freedesktop. org formed the X. Org Foundation, and the Open Group gave it control of the < tt > x. org </ tt > domain name.

In 1988, during the so-called " Unix wars ", DEC joined with IBM, Hewlett-Packard, and others to form the Open Software Foundation ( OSF ) to develop a version of Unix.

In 1994, after AT & T had sold UNIX System V to Novell and the rival Unix International consortium had disbanded, the Open Software Foundation ceased funding of research and development of OSF / 1.

This caused many of AT & T's other licensees of UNIX System V to become concerned that this would put Sun in an advantaged position, and it ultimately led to Digital Equipment, HP, IBM, and others forming the Open Software Foundation ( OSF ) in 1988.

It was formed in 1996 when X / Open merged with the Open Software Foundation.

OSF became part of the newly formed Open Group in 1996.

In 1995, starting with release 3. 2, DEC renamed OSF / 1 AXP to Digital UNIX to reflect its conformance with the X / Open Single UNIX Specification.

The COSE initiative in 1993 can be considered to be the first unification step and the merger of the Open Software Foundation ( OSF ) and X / Open in 1996 as the ultimate step in the end of those skirmishes.

A universally unique identifier ( UUID ) is an identifier standard used in software construction, standardized by the Open Software Foundation ( OSF ) as part of the Distributed Computing Environment ( DCE ).

One of the Seven Principles was declaration of an " Open Process " whereby OSF staff would create Request for Proposals for source technologies to be selected by OSF, in a vendor neutral process.

Technologies which were produced primarily by OSF included ODE, the Open Development Environment-a flexible development, build and source control environment ; TET, the Test Environment Toolkit-an open framework for building and executing automated test cases ; and the operating system OSF / 1 MK from the OSF Research Institute based on the Mach3. 0 microkernel.

TET was produced as a result of collaboration between OSF, UNIX International and the X / Open Consortium.

In May, the Common Open Software Environment ( COSE ) initiative was announced by the major players in the UNIX world from both the UI and OSF camps: Hewlett-Packard, IBM, Sun, Unix System Laboratories, and the Santa Cruz Operation.

As part of this agreement, Sun and AT & T became OSF sponsor members, OSF submitted Motif to the X / Open Consortium for certification and branding and Novell passed control and licensing of the UNIX trademark to the X / Open Consortium.
