(This section is not part of the Open Source Definition.)

We think the Open Source Definition captures what the great majority of the software community originally meant, and still mean, by the term "Open Source". However, the term has become widely used and its meaning has lost some precision. The OSI Certified mark is OSI's way of certifying that the license under which the software is distributed conforms to the OSD; the generic term "Open Source" cannot provide that assurance, but we still encourage use of the term "Open Source" to mean conformance to the OSD. For information about the OSI Certified mark, and for a list of licenses that OSI has approved as conforming to the OSD, see the OSD Certification Mark page.

OSI Board of Directors

The Board of Directors of OSI consists of the following people (in no particular order, except the board president is listed first):

Michael Tiemann - President
Michael Tiemann is a true open source software pioneer. He made his first major open source contribution over a decade ago by writing the GNU C++ compiler, the first native-code C++ compiler and debugger. His early work created world-leading technologies and also informed the first open source business model. In 1989, Tiemann's technical expertise and entreprenurial spirit led him to co-found Cygnus Solutions, the first company to provide commercial support for open source software. During his ten years at Cygnus, Tiemann contributed in a number of roles from President to hacker, helping to lead the company from a fledgling start-up to an admired open source leader. Tiemann is now the CTO of Red Hat, a leading supplier of Linux and Open Source software. In addition to his responsibilities at Red Hat, Tiemann serves on a number of boards, including the Open Source Initiative, the Embedded Linux Consortium, the Jabber Technical Advisory Board, the GNOME Foundation Advisory Board, and the Board of Directors of ActiveState Tool Corp. Tiemann also provides financial support to organizations that further the goals of software freedom, including the Free Software Foundation, the Electronic Frontier Foundation, and the ArsDigita Foundation.

Danese Cooper - Secretary/Treasurer
Danese Cooper has a 15-year history in the software industry and has long been an advocate for transparent development methodologies. Danese worked for six years at Sun Microsystems, Inc. on the inception and growth of the various open source projects sponsored by Sun (including OpenOffice.org, java.net and blogs.sun.com). She was Sun's Chief Open Source Evangelist and founded Sun's Open Source Programs Office. She has unique experience implementing open source projects from within a large proprietary company. She joined the OSI Board in December 2001 and currently serves as Secretary & Treasurer. As of March 2005 Danese has joined Intel to advise on open source projects, investment and support. She speaks internationally on Open Source and Licensing issues.

Russell Nelson (PGP key)
Russell Nelson has been giving away his software since he started writing it in 1974. Prior to his GPLed Freemacs package, there weren't many people to distribute it to. He really came to the fore with his Packet Driver Collection, begun while a staff member at Clarkson University. A GPLed set of DOS Ethernet drivers, they arguably put GPL'ed software on more CPUs than anything prior to Linux. McDonalds uses them in their cash registers, so they're literally a world-wide phenomenon. Supporting free software full-time since 1991, Russell lives and works at home in Potsdam, NY, where he's trying to figure out how to share his 384Kbps connection with his neighbors wirelessly

Ken Coar (PGP key)
Ken Coar is a director and Vice President of the Apache Software Foundation.
