Caldera to Open Source AIM Performance Benchmarks, UNIX Regular Expression Parser and Give "Open Access" to Open UNIX 8 Source Code

Open Source Community, Users to Benefit from Access to UNIX Intellectual Property

FORUM 2001, SANTA CRUZ, CA—August 20, 2001— Caldera International, Inc. (Nasdaq: CALD) today announced it will Open Source the AIM performance benchmarks and the UNIX Regular Expression Parser, along with two UNIX utilities awk and grep. These technologies will be released under the GPL (Gnu General Public License). In a related move, Caldera will also be making the Open UNIX 8 source code available to members of its developer program who request it. Information about the Caldera developer network is available at

These announcements reflect the continued intention on the part of Caldera to progressively contribute source code and to provide ongoing support to the Open Source community. Caldera expects to release further components of the UNIX intellectual property in coming months.

The AIM performance benchmarks are industry-standard server benchmarks acquired from the former AIM Technology. By Open Sourcing the benchmarks, companies may use them to establish independent validation of internal benchmarking. For example, Caldera can independently establish scalability and stability comparisons between Open UNIX 8 and other platforms. Although the sources will be released under the GPL, the use of the AIM Benchmark trademark in connection with these programs will be restricted based on published guidelines to assure the integrity of these tests as industry standard references.

The UNIX Regular Expression Parser is a library function from Open UNIX 8 used by a number of standard UNIX utilities for complex pattern matching of pieces of text. By Open Sourcing this, along with the awk and grep utilities, Caldera begins a process of making some of the original UNIX utilities, upon which the GNU/Linux system was modeled, available as reference sources. This gives the Open Source community an opportunity to reference these implementations and incorporate the best of both source streams into future GPL implementations of these tools.

“Many in the Open Source community have asked Caldera to GPL these technologies,” said John Terpstra, vice president of technology for Caldera International. “We have now delivered these utilities and benchmarks. We have chosen the GPL license to directly support corresponding GNU projects.”

The Regular Expression library and tools will be made publicly available on SourceForge this week at In coming months, Caldera will Open Source other UNIX tools and utilities, including pkgmk, pkgadd, pkgrm, pkginfo, pkgproto and more, as well as the Bourne shell, lex, yacc, sed, m4 and make. The licenses under which these technologies will be Open Sourced will be decided based on community and business needs.

“We are very pleased to offer much of the UNIX source code that laid the foundation for the whole GNU/Linux movement,” said Ransom Love, CEO of Caldera International. “In each case, we will apply the right license – GPL, Berkeley, Mozilla, Open Access, or other license – as appropriate to our business goals.

“Our intention is to steer the middle course in the public debate – it’s not a case of free or Open Source versus proprietary, but both, as the situation warrants. We believe the industry is evolving to a model where source code is freely available, innovation is nurtured at the grass roots, and businesses, such as Caldera, can add value as both product and service companies.”

Open Access to Open UNIX 8

The Caldera Open Access license is intended to give customers the ability to both reference and modify the source code. However, the initial release of source code will be read only, giving customers and software developers a significant reference as they develop applications for Open UNIX 8. In the future, customers and developers will be allowed to change the source code as long as they return the changes to Caldera. This will allow Caldera to maintain a standard business quality platform.

Open UNIX incorporates some proprietary third party technology which means source code for certain third party modules will not be available due to licensing restrictions.

“Over time the licensing and delivery of our Open Access sources will evolve and improve,” explained John Harker, vice president of product management. “Our immediate goal was to provide basic source reference access following the model of SCO’s source products by simply eliminating the license fee. We’re looking at ways to make this as streamlined as possible.”

The Open Access license is free, but will require a signed license agreement. Delivery of the sources in CD form will require a nominal media payment. Further details will be available when the sources are released in October of this year.

Open Source

From its inception, Caldera has shared technology with the Open Source community. Technologies that have been Open Sourced include Webmin – a Web-based administration tool, LIZARD – the award-winning Linux Installation Wizard, Linux Unattended Installation (LUI), Linux Installation Administration (LISA) and Caldera Open Administration System (COAS).
