The Open Group
The Open Group is an industry consortium sponsored by IBM, Sun, HP, Hitachi, and Fujitsu for forming de facto-standards in the field of software engineering, in particular APIs. The Open Group was formed from a merger of the Open Software Foundation (OSF) and X/Open.
The group is most known for its publication of the Single UNIX Specification paper, which (in the eyes of many OS developers) is quickly superseding the POSIX standards. In addition, it is the owner of the UNIX trademark. The Open Group provides conformance testing, certifications and white papers usually concerning Unix operating systems. The Open Group also certifies things that it does not specify and control itself, such as CORBA, the Common Request Broker Architecture implementations (as specified by the OMG), and the Linux Standard Base (from the FSG).
The customer and supplier members participate in forums where they collaborate to develop guides, standards, and specifications. The Architecture forum has developed TOGAF, The Open Group Architecture Framework which is a comprehensive foundation architecture and methods for conducting enterprise information architecture planning and implementation. TOGAF is free to organizations for their own internal noncommercial purposes.
Some of The Open Group documents are only available to members, especially when they are under development. A similar organisation to the Open Group is the W3C.
