The Austin Common Standards Revision Group (CSRG) is a joint technical working group established to develop and maintain the core open systems interfaces that are the POSIX® 1003.1 (and former 1003.2) standards, ISO/IEC 9945 parts 1 to 4, and the core of the Single UNIX Specification.

The approach to specification development is "write once, adopt everywhere", with the deliverables being a set of specifications that carry the IEEE POSIX designation, The Open Group's Technical Standard designation, and the ISO/IEC designation. The current set of specifications is simultaneously ISO/IEC 9945, IEEE Std 1003.1 and forms the core of the Single UNIX Specification.

This unique development combines industry led efforts and the formal standardization activities into a single initiative, and includes a wide spectrum of participants. The group is free and open to participate in and features a balanced set of interest groups including commercial companies, influential figures from the open source community, liaisons from other standards groups, educational and government users, and user groups.

Working with the Open Source community

The group includes developers from the Open Source community. As part of acknowledging their valuable input the copyright holders have made several grants relating to use of the documentation in those projects. Some of these are listed below:

The IEEE and The Open Group grant Permissions to Linux Man Pages project to incorporate material.

The IEEE and The Open Group grant Permissions to the FreeBSD project to incorporate material.

NetBSD OPERATING SYSTEM TO ADD ELEMENTS OF THE POSIX® STANDARD

Other projects that have received permission grants related to use of documentation include Gunnar Ritter's Heirloom Toolkit and other tools, Joerg Schilling's pax and find, Jens Schweikardt book, and the ISPRAS Linux testing project.

How to get Involved

Why you should get involved with POSIX?

Read a backgrounder on the scope, audience and purpose for this standard.

View a set of slides (pdf) or read the long scope for the 2008 revision for an overview.

Read the Frequently Asked Questions file.

The group is chaired by Andrew Josey from The Open Group. The Open Group manages the day to day running of the group providing the chair, the editor and email/web facilities.

Committee Draft Development Procedures

A set of Committee Maintenance Procedures for the Approved Standard are available for information (summary diagram).

The group has adopted the Aardvark comment format for change requests and defect reports. This allows for collation of change requests in order for production of a change request report to be considered at a review meeting.

Joint Working Group Procedures

JDOCS Procedures for Operation of the group are available.
