I think it would be better to use the language from the EUPL
see: http://ec.europa.eu/idabc/servlets/Doc?id=31979
In particular, I think that it is much better to say something like:
In the countries where moral rights apply, the Licensor waives his right to
exercise his
moral right to the extent allowed by law in order to make effective the
licence of the
economic rights here above listed.
The Licensor grants to the Licensee royalty-free, non exclusive usage rights
to any
patents held by the Licensor, to the extent necessary to make use of the
rights granted
on the Work under this Licence.
rather than asserting
The PSF is free to use or disseminate any content ....
because then as part of the PyPi agreeement one can have clauses like this:
Copyleft clause: If the Licensee distributes and/or communicates copies
of the
Original Works or Derivative Works based upon the Original Work, this
Distribution
and/or Communication will be done under the terms of this Licence or of
a later
version of this Licence unless the Original Work is expressly
distributed only under
this version of the Licence. The Licensee (becoming Licensor) cannot
offer or impose
any additional terms or conditions on the Work or Derivative Work that
alter or
restrict the terms of the Licence.
Attribution right: the Licensee shall keep intact all copyright, patent
or trademarks
notices and all notices that refer to the Licence and to the disclaimer
of warranties.
The Licensee must include a copy of such notices and a copy of the
Licence with
every copy of the Work he/she distributes and/or communicates. The
Licensee must
cause any Derivative Work to carry prominent notices stating that the
Work has been
modified and the date of modification.
Legal Protection: This Licence does not grant permission to use the
trade names,
trademarks, service marks, or names of the Licensor, except as required
for
reasonable and customary use in describing the origin of the Work and
reproducing
the content of the copyright notice.
-----------
However, if we do this, I think we will have to add a clause such as
Chain of Authorship
The original Licensor warrants that the copyright in the Original Work
granted
hereunder is owned by him/her or licensed to him/her and that he/she
has the power
and authority to grant the Licence.
Each Contributor warrants that the copyright in the modifications
he/she brings to the
Work are owned by him/her or licensed to him/her and that he/she has
the power and
authority to grant the Licence.
Each time You accept the Licence, the original Licensor and subsequent
Contributors
grant You a licence to their contributions to the Work, under the
terms of this
Licence.
which I think would be a very good idea in any case.
