- poweropen environment — (operating system) (POE) A definition containing API and ABI specifications based on the PowerPC architecture. It is not an operating system. The presence of the ABI specification in the POE distinguishes it from other open systems (POSIX, XPG4, etc.) since it allows platform independent binary compatibility which is otherwise typically limited to particular hardware. The POE is an open standard, derived from AIX and conforming to industry open standards including POSIX, XPG4 and Motif. The POE specification will be publicly available to anyone wishing to produce either application programs or hardware platforms. The PowerOpen Association will provide the necessary conformance testing and POE branding. The POE is hardware bus independent. System implementations can range from laptop computers to supercomputers. It requires a multi-user, multitasking operating system. It provides networking support, an X Window System extension, a Macintosh Application Services extension and Motif. It is conformance tested and certified by an independent party (the PowerOpen Association). The POE specification is targeted for availability in the first quarter of 1994. The PowerOpen Association will soon have some of the information material available on-line.
