Permissive
OpenRoots and BSD 3-Clause License
In freely. Not out without separate relicensing.
Inbound
yesBSD-3-Clause material entering an OpenRoots work
Notice preservation plus a no-endorsement clause. Neither constrains the outer licence. The no-endorsement clause is compatible with the OpenRoots trademark position, which is stricter in the same direction.
Outbound
noOpenRoots material entering a BSD-3-Clause project
Same reasoning as MIT. BSD promises royalty-free use; the Canopy tier may not be royalty-free.
Mechanism
Where the pairing holds and where it breaks.
A matrix cell tells you the answer. These are the clauses that produce it.
Derivative works
One combined, distributable artifact.The combined work carries the OpenRoots instrument; BSD notices and the no-endorsement clause are preserved.
Composite distribution
Both shipped side by side, not merged.Straightforward. Both notices sit in the NOTICE file.
Patent position
Express grants and termination triggers.BSD-3-Clause grants no express patent licence. OpenRoots carries its own patent terms for the OpenRoots portion only.
The royalty
Where the Canopy obligation bites.Attaches to the OpenRoots portion. The BSD portion does not enlarge the base.
Current permanent terms
What holds for as long as the release exists.No automatic conversion occurs. The BSD portion remains BSD and the OpenRoots portion remains OpenRoots.
