License issues in Module::Install

przemo has asked for the wisdom of the Perl Monks concerning the following question:

Dear monks,

I'm an adept of CPAN module-building (Data::Pareto); playing with different installers, I tried Module::Install.

What drawn my attention was the warning

WARNING: 'All rights reserved' in copyright may invalidate Open Source license.

The referred licence text is as follows:

Copyright 2009 Me, all rights reserved.

This program is free software; you can redistribute
it and/or modify it under the same terms as Perl
itself.
[download]

and was generated with Module::Starter:

$ module-starter --module=Data::Pareto --author=Me --email=no@mail.com
+ --mi
[download]

looking into Module/Install/Metadata.pm we can see that such warning is issued for every OSI-approved license with rights-reservation sentence.

Heh ... that's amazing: <quote>The ACTUAL situation is that "All rights reserved" has become utterly meaningless since the creation of the Bern Convention in 1968</quote> Over 40 years later, and it's still being kicked around and mis-interpreted. Cheers, Rob	[reply]

Actually it's a 1886 year convention. Berne_Convention_for_the_Protection_of_Literary_and_Artistic_Works. So it's more than 120 years.	[reply]

"Utterly meaningless" is a misrepresentation of the facts; and the timeline is munged as well. It's become redundant; and according to Wikipedia (with appropriate grains of salt taken) it's only been formally so for a decade.	[reply]
