UNIX 03 is the certification mark for systems conforming to the latest UNIX product standard developed by The Open Group Platform Forum for the Single UNIX Specification version 3. This certification is significant as it further broadens the installed base of UNIX systems in the marketplace to include a popular desktop platform, according to Allen Brown, president and CEO for The Open Group. In addition, Apple's UNIX 03 certification is a milestone for the UNIX certification program since Mac OS X is the first operating system derived from the open source BSD base of historical UNIX products to meet the certification requirements, he adds.
The Single UNIX Specification is a set of open specifications that define the requirements for a conformant UNIX system. Operating systems that support the Single UNIX Specification provide a set of standard interfaces allowing the catalog of back office and other applications
that comply with the specification to be ported between the compliant operating systems. With certification of Mac OS X, end users now benefit from such applications available on a range of certified UNIX 03 systems available from major vendors, including Apple, Fujitsu, IBM,
Hewlett-Packard, and Sun Microsystems, Brown says.
