OpenRoots and Business Source License 1.1
A close commercial neighbour, but not safely combinable without separate relicensing.
Inbound
noBUSL-1.1 material entering an OpenRoots work
BUSL restricts production use until its change date, and that restriction cannot be carried by an OpenRoots instrument, whose Root tier permits production use immediately below the threshold. Taking BUSL material in would mean promising recipients something BUSL forbids.
Outbound
noOpenRoots material entering a BUSL-1.1 project
Symmetrically not. Each licence imposes conditions the other cannot represent.
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.Not permissible in either direction under current OpenRoots terms.
Composite distribution
Both shipped side by side, not merged.Aggregation is possible but the BUSL production-use restriction still applies to its portion, which usually defeats the point of the combination.
Patent position
Express grants and termination triggers.BUSL-1.1 grants no express patent licence. Its change licence often does.
The royalty
Where the Canopy obligation bites.BUSL restricts use outright rather than pricing it. OpenRoots prices it. These are different mechanisms and neither can express the other.
Current permanent terms
What holds for as long as the release exists.BUSL may change later according to its own terms. OpenRoots does not, so the problem does not disappear on the OpenRoots side by time alone.
