product with their forthcoming OpenLinux distribution in 1997. By 1997, when the OpenLinux distribution was first released, Caldera had taken on the form that it would be most remembered for. Caldera had switched over to the high end Linux product. The "business" Linux distribution became more rich with features with bundled proprietary software. However, it became less community oriented and was released less frequently than other Linuxes did. Other differences included automated configuration for administration tools, paid technical support staff, built-in consistent default GUI, and a range of supported applications. Over the next five years, Caldera Systems offered additional commercial extensions to Linux. They licensed Sun's Wabi to allow people to run Windows applications under Linux. Additionally, they shipped with Linux versions of WordPerfect (from Novell and later Corel) and CorelDRAW. Since many of their customers used a dual boot setup and FIPS was unreliable, they shipped with PowerQuest's PartitionMagic to allow their customers to non-destructively repartition their hard disks. In partnership with IBM they produced the first Linux distribution which was DB2 compatible. With the Oracle Corporation they became the target platform for the Linux port of the Oracle database. Other ventures included starting the Blackdown Java project, and creating professional certification. They also formed strong partnerships with SCO's value-added reseller market and started laying the groundwork for OEM sales of Unix-based vertical applications. Caldera Systems offered three versions of OpenLinux: OpenLinux Lite was a freely downloadable version. OpenLinux Base was a USD 99 version with a few extensions. OpenLinux Standard was USD 299 and was their fully featured product. In addition to other people's applications, they created many Linux extensions to fill voids where no other commercial company was. Caldera Systems began working on a Linux equivalent of replacing the Microsoft Exchange Server and Microsoft Outlook that would eventually become Volution Messaging Server, which offered calendaring/scheduling options with shared busy/free information, SSL support for e-mail and easy configuration. Additionally, Caldera Deutschland created the first fully graphical installer for Linux, called Lizard, starting in November 1998. They invented browser-based Unix system administration, created the webmin project, and employed its developer Jamie Cameron between 1999 and 2001. Caldera Systems created a full featured GUI system administration tool called Caldera Open Administration System (COAS). The tool was a unified, easy to use administration tool with a modular design. With its scalability and broad scope abilities, it featured: Portability (specifics encapsulated in
