Quoted from introduction text found at
In short, Open CASCADE Technology Public License is LGPL-like with certain differences. You are permitted to use Open CASCADE Technology within commercial environments and you are obliged to acknowledge its use. You are also obliged to send your modifications of the original source code (if you have made any) to the Initial Developer (i.e. Open CASCADE S.A.S.).
The last sentence is clearly wrong, OCTPL 6.3 does no longer
require changes to be sent back.
Can someone please update the page above to remove this phrase?
The other differences seem also to be void: LGPL can be used
within commercial environments, and I do not see how OCTPL
6.3 differ from LGPL 2.1 section 6 with respect to
acknwoledging its use.
To me, OCTPL 6.3 is similar to LGPL 2.1, except that it uses
different words and a different name, which is very
inconvenient when someone has to wonder whether this license
is compatible with another license.
Can someone from the dev team please tell me what are the
real differences between OCTPL 6.3 and LGPL 2.1, and if
there are only cosmetic differences, would you consider
relicensing Open Cascade to LGPL 2.1 to ease integration of
Open Cascade with other software?
Thanks for your consideration.
