Organization

AIX Direction

IEEE (Institute of Electrical & Electronics Engineers)

IEEE is an accredited standards organization. POSIX is a group of related standards that are being developed to support application portability.

AIX will continue to support POSIX standards as they evolve. Currently, the IEEE and The Open Group are jointly revising the POSIX.1(1003.1-1996) and POSIX.2(1003.2-1992) standards. The collaboration is known as the Austin Common Revision Standards Group. The most important POSIX activities relating to AIX are:
- System API
- Commands and Utilities
- Security
- System Administration.

Open Group (Open Group Ltd.)

Open Group produces specifications in support of application portability and interoperability. A branding program is in place that allows compliant products to obtain an Open Group brand.

AIX will continue to support Open Group specifications and the on-going work to enhance application portability across UNIX implementations by multiple vendors. Work on the Single UNIX specification V3 was completed and the document has been released as SUSv3 by the The Open Group, POSIX 1003.1-2004 by the IEEE and IEC 9945:2004 by ISO. AIX complies with the Single UNIX specification V3, the specification for obtaining the UNIX 03 brand, and is UNIX 03 base branded on the current AIX 5L for POWER 5.2 release.

Java Community Process

The Java Community Process (JCP) program is the formalization of the open process that Sun Microsystems, Inc. has been using since 1995 to develop and revise Java technology specifications in cooperation with the international Java community.

IBM leads and/or participates in a large number of Java Specification Requests (JSRs). See http://www.jcp.org/en/jsr/all for a complete list of JSRs. For example, IBM is the SPEC lead of the following JSRs:

The Free Standards Group

The Free Standards Group non-profit corporation organized to accelerate the use and acceptance of open source technologies through the application, development and promotion of standards.

IBM supports the Free Standards effort. IBM is involved with a number of LINUX standards, some examples are:
- The Linux Standard Base (LSB)
- Linux Internationalization Initiative (Li18nux)
- Filesystem Hierarchy Standard
