Open Sky Standard License (OSSL)
Simple & Convenient
The OSSL is a simple and convenient license that provides our clients with the right to use, reproduce, and modify the original source code subject to the restrictions contained in the license.
The Open Sky Standard License is available here in plain text.
Who created the OSSL?
The OSSL is the result of our clients, our software developers, and a host of lawyers coming together to design a flexible license that satisfies everyone.
What am I allowed to do with OSSL code?
The OSSL allows you to run the software, fix any bugs, build new software modules as add-ons, and sell (re-license) the original software and any new modules you develop.
What am I not allowed to do with OSSL code?
You may not pursue an intellectual property infingement claim against Open Sky for using similar software or techniques to satisfy other Open Sky clients.
Open Sky uses the OSSL for three primary reasons: (1) to allow clients to freely obtain source code and modify that code without Open Sky's help and without potentially threatening Open Sky or other clients of Open Sky, (2) to insure no single client obtains a lock on Open Sky's core intellectual property and techniques, and (3) to insure the highest quality code for all clients.
