Platform
The Platform Forum standardizes the platform infrastructure on which applications can be built. Focus is on open standards for operating systems, including the UNIX® system, POSIX®,  open source operating systems such Linux® and BSD, real-time systems and network computing. The Forum is also the specification authority for The Open Group's UNIX certification program.

   

What We Do
A wide spectrum of Forum participants, including commercial, government, and open source interests, are working on:

The Single UNIX Specification
Extending existing specifications, providing new interpretations of the specifications and correcting any identified errors, as well aligning the specifications with the IEEE Portable Operating System Interface (POSIX®) and ISO/IEC standards. Among other platform aspects, the specification encompasses the base operating system environment, networking services, windowing system services, internationalization aspects and programming languages.

Test Suites and Certification Programs
Updating, extending and adapting existing test suites and certification programs to include the expanding specifications and various implementations.
