==History==
[[Open Software Foundation]] (OSF) came about to a large degree as part of the [[Unix wars]] of the 1980s. After [[Sun Microsystems]] and [[AT&T Corporation]] worked together to produce [[UNIX System V|UNIX System V Release 4]] (SVR4) and refused to commit to fair and open licensing of Unix source code, many of the other Unix vendors felt their own market opportunities were unduly disadvantaged. The Distributed Computing Environment is a component of the OSF offerings, along with Motif and Distributed Management Environment (DME).
As part of the formation of OSF, various members contributed many of their ongoing research projects as well as their commercial products. For example, HP/Apollo contributed its Network Computing Environment (NCS) and CMA Threads products. Siemens Nixdorf contributed its X.500 server and ASN/1 compiler tools. At the time, network computing was quite popular, and many of the companies involved were working on similar [[Remote procedure call|RPC]]-based systems. By integrating security, RPC and other distributed services on a single "official" distributed computing environment, OSF could offer a major advantage over SVR4, allowing any DCE-supporting system (namely OSF/1) to interoperate in a larger network.
