VISUALIZATION

SANTA CRUZ, CA -- 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 www.caldera.com/partners/developer/ 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 http://unixtools.sourceforge.net. 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."
