License-wide duties

This license states no duties that apply to the work as a whole.

What applies by default

The statements above are the library's reading of this license: each is marked with the sentence it rests on, or as a library convention where the text is not explicit. The statements below are the ones the DALICC reasoner supplies for acts the license says nothing about, from the default rules of the dependency graph it reasons with. Each one names the legal source it rests on. None of it is in the record.

No default rule of that graph reaches this license: it speaks about every act the rules are about.

Further terms

These are the things the license says about itself beyond the acts it permits, forbids and requires: when it ends, how long there is to put a breach right, which law governs it, and so on. A term that comes from the DALICC vocabulary links to its definition.

Terminates on breach: Yes

Clauses

Warranty disclaimer

CNRI is making Python 1.6b1 available to Licensee on an "AS IS" basis. CNRI MAKES NO REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED. BY WAY OF EXAMPLE, BUT NOT LIMITATION, CNRI MAKES NO AND DISCLAIMS ANY REPRESENTATION OR WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE OR THAT THE USE OF PYTHON 1.6b1 WILL NOT INFRINGE ANY THIRD PARTY RIGHTS.

Limitation of liability

Additional clauses

Alternately, in lieu of CNRIs License Agreement, Licensee may substitute the following text (omitting the quotes): "Python 1.6, beta 1, is made available subject to the terms and conditions in CNRIs License Agreement. This Agreement may be located on the Internet using the following unique, persistent identifier (known as a handle): 1895.22/1011. This Agreement may also be obtained from a proxy server on the Internet using the URL:http://hdl.handle.net/1895.22/1011". 6.

Nothing in this License Agreement shall be deemed to create any relationship of agency, partnership, or joint venture between CNRI and Licensee.

Review

Second review: not yet done
Record changed since this review: yes (version 2, 2026-09-24)
Findings: 9 recorded, 7 applied to the record, 0 proposed

Models the CNRI Open Source License Agreement for Python 1.6 beta 1, one of the agreements in the chain behind the PythonLicense20 record the library already holds. Its one retention condition is the licence agreement itself, not a copyright notice, which is what separates it from the GPL compatible CNRI agreement. Nothing here is legal advice.

9 findings

major Rubric 3 odrl:permission applied

Clause 2 grants "a non-exclusive, royalty-free, world-wide license to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python 1.6b1 alone or in any derivative version". The record therefore permits reproduce, display, present, distribute, modify, derive, commercial use, derivative works and modified works. The agreement says nothing about charging, so dalicc:chargeDistributionFee is permitted, as in 333 of the 344 existing records.
major Rubric 4 odrl:prohibition applied

Clause 7 states "This License Agreement does not grant permission to use CNRI trademarks or trade name in a trademark sense to endorse or promote products or services of Licensee, or any third party", modelled as a dalicc:promote prohibition. No right to relicense is granted, so dalicc:ChangeLicense is prohibited. No sublicensing right is granted either; the record makes no odrl:grantUse statement rather than prohibiting it. (Corrected on 2026-09-15 by the verification pass: see the rubric 3 finding on relicensing below.)
major Rubric 5 odrl:duty applied

Clause 2 conditions the grant on one thing only: "that CNRIs License Agreement is retained in Python 1.6b1, alone or in any derivative version prepared by Licensee". That is cc:Notice, and it is attached to odrl:distribute, odrl:modify and odrl:derive. No cc:Attribution duty is written, because this agreement, unlike the GPL compatible one, does not require a copyright notice to be retained. Clause 3 adds dalicc:modificationNotice on odrl:modify and odrl:derive.
major Rubric 6 dalicc:additionalClauses applied

Clauses 4 and 5 are quoted word for word in dalicc:WarrantyDisclaimer and dalicc:LiabilityLimitation. The substitute notice text of clause 2, the automatic termination of clause 6 and the whole of clause 7 are quoted in dalicc:additionalClauses.
major Rubric 7 cc:jurisdiction applied

Clause 7 states "This License Agreement shall be governed by and interpreted in all respects by the law of the State of Virginia, excluding conflict of law provisions", while the grant itself is world-wide. Virginia is a state, not a country, and the bpicounty vocabulary the library uses for jurisdiction ports has no IRI for it, so cc:jurisdiction stays dalicc:worldwide and the clause is quoted. The association may want to decide whether a sub-national choice of law deserves its own property.
gap Rubric 8 dalicc:additionalClauses none

Automatic termination on breach has no property to hang it on; proposed term dalicc:terminatesOnBreach over the existing dalicc:terminationOnBreach concept. The clause is quoted.
info Rubric 9 record none

The consistency check of app.services.composer with the dependency graph dg_default returned an empty conflict list.
major Rubric 10 record applied

Follows licensedata/licenses/PythonLicense20.ttl for the permission set and the modification notice. It deliberately does not copy four of that record's prohibitions (odrl:grantUse, cc:ShareAlike, dalicc:addLimitation and dalicc:addStatement) nor its dalicc:chargeDistributionFee prohibition, because neither this text nor the PSF text states any of them. The existing record was not edited; the observation is passed to the consolidation.
major Rubric 3 odrl:permission applied

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 earlier reading wrote is removed. The text reads: "Subject to the terms and conditions of this License Agreement, CNRI hereby grants Licensee a non-exclusive, royalty-free, world-wide license to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python 1.6, beta 1 alone or in any derivative version, provided ... CNRI's License Agreement is retained in Python 1.6, beta ..." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.

History

This license model has 2 versions. Version 2 is the one served today; every earlier version keeps its own address, so a conclusion drawn from one of them can still be checked against it.

Version 2 current2026-09-24 Giray Havur

The changes since version 1 recorded which sentence of the text each statement rests on, named the license the record itself is published under and removed the quotes that do not name the act they support.
