Review finding Added Python-2.0 and the missing dct:source.

Python License-2.0 version 2 2026-09-24

removed Prohibition: Grant use

Manual edit The review's finding on family consistency: the record prohibited odrl:grantUse, cc:ShareAlike, dalicc:addLimitation, dalicc:addStatement and dalicc:chargeDistributionFee, none of which the PSF License Agreement version 2 states. Clause 2 grants the right 'to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python alone or in any derivative version' and says nothing about fees, so the distribution fee is permitted as it is on the other permissive records.

Python License-2.0 version 2 2026-09-24

removed Prohibition: Derive

Review finding Clause 2 grants "a nonexclusive, royalty-free, world-wide license to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python alone or in any derivative version". The record prohibited odrl:derive and cc:DerivativeWorks. Removed both and added the permissions with the duties of clauses 2 and 3.

Python License-2.0 version 2 2026-09-24

changed Prohibition: Promote

was Prohibition: Promote

Clause 2 grants the right 'to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python alone or in any derivative version' and says nothing about fees, so the distribution fee is permitted as it is on the other permissive records.

removed Prohibition: Derivative works

Review finding Clause 2 grants "a nonexclusive, royalty-free, world-wide license to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python alone or in any derivative version". The record prohibited odrl:derive and cc:DerivativeWorks. Removed both and added the permissions with the duties of clauses 2 and 3.

Python License-2.0 version 2 2026-09-24

changed Permission: Distribute, with the duties Attribution, Notice

was Permission: Distribute, with the duties Attribution

Review finding Clause 2 requires that "PSF's License Agreement and PSF's notice of copyright ... are retained in Python alone or in any derivative version". The distribute permission carried cc:Attribution but not cc:Notice. Added.

Python License-2.0 version 2 2026-09-24

changed Permission: Derive, with the duties Attribution, Notice, Modification notice

was Permission: Derive, with the duties Attribution, Notice, Modification notice

Manual edit The statement now quotes the sentence of the licence text it rests on: "Subject to the terms and conditions of this License Agreement, PSF hereby grants Licensee a nonexclusive, royalty-free, world-wide license to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python alone or in any derivative version, provided, however, that PSF's License Agreement and PSF's notice of copyright, i.e., "Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006 Python Software Foundation; All Rights Reserved" are retained in Python alone or in any derivative version prepared by Licensee."

Python License-2.0 version 2 2026-09-24

added Permission: Charge distribution fee

Manual edit The review's finding on family consistency: the record prohibited odrl:grantUse, cc:ShareAlike, dalicc:addLimitation, dalicc:addStatement and dalicc:chargeDistributionFee, none of which the PSF License Agreement version 2 states. Clause 2 grants the right 'to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python alone or in any derivative version' and says nothing about fees, so the distribution fee is permitted as it is on the other permissive records.

Python License-2.0 version 2 2026-09-24

added Permission: Change license, with the duties Use a compliant license

Manual edit Permit relicensing on permissive licences; the notice clause is a duty, not a bar. Library convention 15: a licence that asks for no reciprocity and no source code asks only that the notice travels with the copy, which is a duty on the acts it governs and not a bar on putting the copy under other terms. dalicc:ChangeLicense is therefore a permission here, and the prohibition the record carried before is removed. The text reads: "Permission to use, copy, modify, and distribute this software and its documentation for any purpose and without fee is hereby granted, provided that the above copyright notice appear in all copies and that both that copyright notice and this permission notice appear in supporting documentation, and that the name of Stichting Mathematisch Centrum or CWI not be used in advertising or publicity pertaining to distribution of the software without specific, written prior permission." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.

Python License-2.0 version 2 2026-09-24

changed Permission: Change license, with the duties Use a compliant license

was Permission: Change license, with the duties Use a compliant license

Manual edit The statement is marked as a library convention, family rule 15: Permissive records permit relicensing: the text does not state it in as many words. Its duty dalicc:compliantLicense is marked as a library convention, family rule 15: Permissive records permit relicensing.
