Apple Registers Mac OS X 10.8 Mountain Lion to the UNIX® 03 Standard

By Andrew Josey, The Open Group

Today, Apple, Inc. released the latest version of the Mac OS X, version 10.8, also known as “Mountain Lion.” In addition to the product’s release, we are pleased to announce that Mac OS X Mountain Lion has achieved certification to The Open Group UNIX® 03 standard, which is the mark for systems conforming to the Single UNIX Specification, Version 3.

The Single UNIX Specification is an open specification that defines the set of required interfaces for a conformant UNIX system. Support for the Single UNIX Specification permits wide portability of applications between compliant and compatible operating systems. High reliability, availability and scalability are all attributes associated with certified UNIX® systems. By registering operating systems as compliant with the Single UNIX Specification, UNIX system suppliers assure their users of the stability, application portability and interoperability of their products.

Over the years, Apple has been a great supporter of the UNIX standard, and today, Mac OS X is the most widely used UNIX desktop operating system. Apple’s installed base—over 50 million users— and commitment to the UNIX standard as a platform is significant to the UNIX certification program. We look forward to continuing to work with Apple and our other UNIX partners in promoting open and interoperable operating systems as the specification continues to evolve.

He is currently managing the standards process for The Open Group, and has recently led the standards development projects for TOGAF 9.1, ArchiMate 2.0, IEEE Std 1003.1-2008 (POSIX), and the core specifications of the Single UNIX Specification, Version 4. Previously, he has led the development and operation of many of The Open Group certification development projects, including industry-wide certification programs for the UNIX system, the Linux Standard Base, TOGAF, and IEEE POSIX.

UNIX® is Still as Relevant as Ever

By Andrew Josey, The Open Group

Despite being as old as man landing on the moon, the UNIX® operating system is still as relevant today as it was in 1969. UNIX is older than the PC, microprocessor and video display at 43. In fact, few software technologies since have since proved more durable or adaptable than the UNIX operating system. The operating system’s durability lies its stability – this is why the UNIX programming standard is crucially important. Since 1995, any operating system wishing to use the UNIX trademark has to conform to the Single UNIX Specification, a standard of The Open Group. In this blog we identify some of the reasons why this standard is still relevant today.

One of the key reasons is that the UNIX standard programming interfaces are an integral and scalable foundation for today’s infrastructure from embedded systems, mobile devices, internet routers, servers and workstations, all the way up to distributed supercomputers. The standard provides portability across related operating systems such as Linux and the BSD systems and many parts of the standard are present in embedded and server systems from HP, Oracle, IBM, Fujitsu, Silicon Graphics and SCO Group as well as desktop systems from Apple.

The Single UNIX Specification provides a level of openness which those without the standard cannot, ensuring compatibility across all these platforms. Because the standard establishes a baseline of core functionality above which suppliers can innovate, applications written to the standard can be easily moved across a wide range of platforms. It enables suppliers to focus on offering added value and guarantee the underlying durability of their products with the core interfaces standardised. UNIX interfaces have found use on more machines than any other operating system of its kind, demonstrating why having a single, maintained standard is incredibly important. The UNIX standard enables customers to buy with increased confidence, backed with certification.

The Open Group works closely with the community to further the development of standards conformant systems by evolving and maintaining the value of the UNIX standard. This includes making the standard freely available on the web, permitting reuse of the standard documentation in open source projects, providing test tools, and developing the POSIX and UNIX certification programmes.

The open source movement has brought new vitality to UNIX and its user community is larger than ever including commercial vendors, operating system developers and an entirely new generation of programmers. Forty years after it was first created, UNIX is still here, long after Buzz Aldrin and Neil Armstrong hung up their moon boots. With the right standards in place to protect it, there’s no reason why it shouldn’t continue to grow in the future.

 UNIX is a registered trademark of The Open Group.

“Making Standards Work®”

By Andrew Josey, The Open Group

Next month as part of the ongoing process of “Making Standards Work®,” we will be setting standards and policy with those attending the member meetings at The Open Group Conference, London, (May 9-12, Central Hall Westminster). The standards development activities include a wide range of subject areas from Cloud Computing, Tools and People certification, best practices for Trusted Technology, SOA and Quantum Lifecycle Management, as well as maintenance of existing standards such as TOGAF® and ArchiMate®. The common link with all these activities is that all of these are open standards developed by members of The Open Group.

Why do our members invest their time and efforts in development of open standards? The key reasons as I see them are as follows:

  1. Open standards are a core part of today’s infrastructure
  2. Open standards allow vendors to differentiate their offerings by offering a level of openness (portable interfaces and interoperability)
  3. Open standards establish a baseline from which competitors can innovate
  4. Open standards backed with certification enable customers to buy with increased confidence

This is all very well, you say — but what differentiates The Open Group from other standards organizations? Well, when The Open Group develops a new standard, we take an end-to-end view of the ecosystem all the way through from customer requirements, developing consensus standards to certification and procurement. We aim to deliver standards that meet a need in the marketplace and then back those up with certification that delivers an assurance about the products or in the case of people certification, their knowledge or skills and experience. We then take regular feedback on our standards, maintain them and evolve them according to marketplace needs. We also have a deterministic, timely process for developing our standards that helps to avoid the stalemate that can occur in some standards development.

Let’s look briefly at two of the most well known Open Group standards:  UNIX® and TOGAF®,. The UNIX® and TOGAF® standards are both examples of where a full ecosystem has been developed around the standard.

The UNIX® standard for operating systems has been around since 1995 and is now in its fourth major iteration. High reliability, availability and scalability are all attributes associated with certified UNIX® systems. As well as the multi-billion-dollar annual market in server systems from HP, Oracle, IBM and Fujitsu, there is an installed base of 50 million users* using The Open Group certified UNIX® systems on the desktop.

TOGAF® is the standard enterprise architecture method and framework. It encourages use with other frameworks and adoption of best practices for enterprise architecture. Now in its ninth iteration, it is freely available for internal use by any organization globally and is widely adopted with over 60% of the Fortune 50 and more than 80% of the Global Forbes 50. The TOGAF® certification program now has more than 15,000 certified individuals, including over 6,000 for TOGAF® 9.

If you are able to join us in London in May, I hope you will be able to also join us at the member meetings to continue making standards work. If you are not yet a member then I hope you will attend the conference itself and network with the members to find out more and consider joining us in Making Standards Work®!
