Hello, I am packaging Zope Toolkit for Ubuntu, but archive admins have noticed that some files have "Zope Public License, Version 2.0" in their headers. I guess this is unintentional, but now I have to find such files and specify their license separately. Can I simply change the version number to 2.1 and commit to the Zope repository? The affected files that I care about are attached. zope.server/src/zope/server/http/tests/test_wsgiserver.py even specifies ZPL 1.1, that might be incompatible with 2.1. At the same time, LICENSE.txt and COPYRIGHT.txt files that are still missing in many packages could be added, using zope.repositorypolicy scripts. While investigating this, I noticed that there is only the ZPL 2.0 at http://www.opensource.org/licenses/zpl.php that is correctly categorized as "Non-reusable" in http://www.opensource.org/licenses/category . The ZPL 2.1 is now reusable, but it is not visible at opensource.org, and therefore its claim "This license has been certified as open source." is not true. Two more packages have other copyright problems: zope.pagetemplate contains non-free files. See https://bugs.launchpad.net/zope.pagetemplate/+bug/607228 zope.structuredtext contains some files that are (C) Digital Creations and link to a non-existing COPYRIGHT.html. This makes them non-free as well. Who can fix the mentioned problems? -- Gediminas Paulauskas
