Dual Licensing
Pellet is available under a dual licensing whereby use of Pellet in projects that are licensed so as to be compatible with AGPL Version 3 may use Pellet under the terms of that license. However, if AGPL Version 3.0 terms are incompatible with your planned use of Pellet, alternative license terms are available from Clark & Parsia LLC—please direct inquiries about Pellet licensing to sales@clarkparsia.com or +1 202 408 8770.
Why Dual Licensing?
Based on a “quid pro quo” approach, dual licensing is the most equitable licensing scheme, since it provides open source terms for those who are developing open source software, while also making it possible to provide proprietary terms for those who are developing proprietary software. This scheme allows Clark & Parsia LLC to respond in-kind to the different segments of the Pellet customer base with the terms most amenable to customer needs. The dual license model also provides for a limited monetization of Pellet development outcomes such that future development of Pellet becomes more, rather than less likely.
Which License Should I Choose?
If your software is licensed under a recognized open source license that is compatible with AGPL 3.0, then you can use Pellet under its open source license terms without further consideration.
However, if your software is not licensed under an open source compatible license, but rather is available under a proprietary license, then you should contact Clark & Parsia LLC in order to arrange alternative license terms to cover your use of Pellet.
Thus,
- If you derive a commercial advantage by using Pellet with a closed source solution, you must arrange alternative license terms for your use of Pellet which will, at a minimum, remove the need to publish your source code.
- If you wish to use Pellet under its open source terms, you must contribute back to the community the source code for the solution you use Pellet with, so that others may benefit from it as you benefit from Pellet.
