Usage Requires No License Fee

OREM, UT-JUNE 17, 1997, The Canopy Group Inc. today announced the immediate Internet availability of a cross-platform, Windows compatible Application Programming Interface (API) and provisional Application Binary Interface (ABI). This technology was formerly known as the ATWIN API under the company name of Willows Software (a division of the Canopy Group) and requires no license fee. The source code and provisional binary license allows for the rapid continuation of the technology with increased support for small and large ISVs.

The TWIN API is a cross-platform Windows Application Programming Interface (API) and provisionally, an Application Binary Interface (ABI). The API allows developers and companies to port and provide Windows applications and utilities for operating system platforms other than Windows. The ABI allows Windows applications to run unmodified on many diverse platforms including but not limited to: Novell NetWare, Apple Macintosh and Caldera OpenLinux.

The TWIN API also provides Windows API compatibility, supplying interfaces for 16 and 32 bit Windows APIs. Other popular Windows interfaces such as WinSock, Shell, Registry, Common Dialogs and Common Controls are also provided.

"APIs should belong to the community at large, no one entity should control them," said Ralph Yarro, general manager of The Canopy Group, Inc. "We want users to have the freedom to choose the platforms that best serve them and not be limited by the lack of applications that run on them. That's why we support not only this action, but other developments like the Wine Project and Java as well. We greatly appreciate the investment of time and money that developers have made to the Windows API. It is our intention to give them a free and efficient alternative for moving their products to other platforms without further investment."

Rob Farnum, the inventor of the Willows technology, is under contract with The Canopy Group to oversee the Internet development of the technology and resulting product direction and evangelization. "After watching the development of Linux over the last couple of years, I have become convinced that the Internet development community will keep the Willows technology moving forward with the best solutions possible," said Mr. Farnum. This bold move by The Canopy Group will allow the technology to benefit from the worldwide contributions of the best that the development community has to offer."

The Canopy Group's original intent for the Willows technology was to support their Caldera, Inc. Linux offering. However, this opportunity will now benefit the entire Internet community. "This action by the Canopy Group is a good one for us and the industry." said Bryan Sparks, president and CEO of Caldera, Inc. "The TWIN API/ABI broadens the scope of solutions that Caldera can provide on our OpenLinux platforms. It also provides resellers with an alternative for providing their custom solutions on other platforms. It gives them and their customers increased freedom-of-choice and better overall solutions."

"We have watched the Wine group's Internet success closely, and believe that the Willows code will help them be even more successful," continued Ralph Yarro of The Canopy Group. "The Wine project is a free Windows emulator currently being developed by volunteers on the Internet. The publication of the Willows source code means that both Willows and Wine will be able to benefit from each other's work, and build an even better emulator by combining the strengths of both products." Alexandre Julliard, leader of the Wine project concurs. "This is very exciting for us, being able to share code and ideas with Willows. It will be a huge help to fulfill our dream of a free Windows environment. It is a great day for the free software world!"
