Plain Text Version

The Symisc Public License is a three-clause license, GPL compatible and is equivalent to the more popular Sleepycat license (An OSI approved license) and permits use of our products in open source projects or in applications that are not distributed to third parties.

If you do not want to release the source code for your application, you may purchase a commercial license from Symisc Systems.

licensing questions

  1. What does "redistribute" mean?

    "redistribution" in the open source world means your application is distributed to one or more third parties. Giving an application to customers, even in alpha or beta releases, is redistribution. Giving contractors, affiliates, parent organizations or subsidiaries, business partners or support vendors a copy of the application is generally redistribution.

    Whether or not you charge money for your application does not matter. The only condition is redistribution.

    Building/Releasing an application for internal use is not considered redistribution.

    Again, if you have any questions on licensing and/or for legal issues, please send an email to:

    legal@symisc.net.

  2. What must I release as open source?

    Under the SPL, you must release the complete source code for the application that embed the product in question. You do not need to release the source code for components that are generally installed on the operating system on which your application runs.
