Open CASCADE Technology Public License

I would add that a *very* quick skim of the license raises a few issues
which would make me unlikely to use the license whether or not it can be
considered open source (also, last I checked, OSI's legal pages did *not*
claim a right to the mere term "open source").  The basic issue is that I do
not generally like licenses which require private modifications to be
contributed back to the initial author (here it is unclear).

The following paragraph (which takes effect on modification) seems fairly
onerous:
"You document all Your Modifications, indicate the date of each such
Modifications, designate the version of the Software You used, prominently
include a file carrying such information with respect to the Modifications
and duplicate the copyright and other proprietary notices and disclaimers
attached hereto as Schedule "B" or any other notices or disclaimers attached
to the Software with your Modifications."

The following statement in the summary also states:
"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.).
Complete text of the license is given below."

However, I am unable to determine how the above sentence actually is brought
about in the license.  It does appear that one is required to acknowledge
that as the intent of the license however.

In short, I am hard pressed to come up with any cases where this license is
something I would consider using or being a party to.


IANAL, TINLA, I am just a lowly open source developer who codes on FOSS
projects full-time for customers.

Best Wishes,
Chris Travers
