I think we *really* need to determine what is subject to OSI approval.

Christopher Sean Morrison via License-review dixit:

Part B itself says it is the software licence, so if only Part B is
the thing to be OSI approved, I think we’re good. It’s already somewhat
marked as separate due to that… but if OSI reviews Part B, it probably
needs a name if “3D Slicer License” the name of the whole thing. (That
being said, due to the legacy/nōn-reusable approval, we could probably
denote “3D Slicer License, Part B” to be the licence.)

However, the preamble says:

> Part C of this Agreement applies to all transactions with Slicer.

So, is Part C part of the licence or not? Considering recipients
of the software can either get it from Slicer (with Part C) or from
others, under the sublicence right granted (without Part C), this
can be tricky, especially since court designations have not been
looked at favourably recently. (On the other hand this is for legacy
nōn-reusable approval, so the point is probably minor.)

when God enlightens him. Or only God invents algorithms, we merely copy them.
