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.

Promote by default rule (adopted)

This license says nothing about Promote, and the graph applies this reading in all jurisdictions it covers: it is not permitted unless the license permits it.

A licence that says nothing about endorsement is read as not allowing it: the licence gives the licensee no right to use the licensor's name or marks in a way that states or implies that the licensor endorses the licensee or its product, while stating truthfully that a work is based on or uses the licensed work is a different act that this rule does not decide. A copyright licence grants rights in the work, and the right to use a name or a trademark is a separate right under trademark law and the protection of names, which a silent copyright licence does not pass on. Combining a licence that is silent about endorsement with one that permits it shows a conflict marked as coming from this rule.

Basis Trademark and name rights are separate from copyright: Regulation (EU) 2017/1001 article 9 lets the proprietor of an EU trade mark prevent all third parties not having his consent from using the sign in the course of trade, and Directive (EU) 2015/2436 article 10, 15 U.S.C. 1114 and 1125(a), section 12 BGB and section 43 ABGB protect marks and names in the same way. The library's evidence is Creative Commons 4.0 section 2(b)(2): Patent and trademark rights are not licensed under this Public License. A copyright licence that is silent grants no right to use the licensor's name or marks to suggest endorsement (Worldwide)

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.

Clauses

Warranty disclaimer

THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

Accepting warranty or additional liability

you may offer support or warranty protection for a fee

Additional clauses

Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.

Review

Status: Reviewed against the license text
Last checked: 2026-09-15
Reviewer: Giray Havur
Verdict: corrected during the review
Record changed since this review: yes (version 2, 2026-09-24)
Findings: 9 recorded, 7 applied to the record, 0 proposed

The record models the Affero GPL exactly like GPL-3.0-only and quotes the network clause of section 13 in dalicc:additionalClauses. The SPDX identifier it carried, "AGPL-3.0", is deprecated on the SPDX list; it was replaced by AGPL-3.0-only. The publisher field held the license name instead of a publisher, and the right to charge for conveying copies was missing.

9 findings

minor Rubric 1 spdx:licenseId applied

The record carried the deprecated SPDX id "AGPL-3.0". SPDX replaced it with AGPL-3.0-only and AGPL-3.0-or-later; the record models no "any later version" option, so AGPL-3.0-only is the matching id.
minor Rubric 1 dct:publisher applied

dct:publisher held the string "GNU Affero General Public License", that is the name of the license, not its publisher. Corrected to the Free Software Foundation, in line with the other three GNU records.
major Rubric 3 odrl:permission applied

Section 4 states: "You may charge any price or no price for each copy that you convey." Added the missing dalicc:chargeDistributionFee permission.
gap Rubric 8 vocabulary none

The defining clause of this license cannot be modelled. Section 13 states: "if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network ... an opportunity to receive the Corresponding Source". Remote interaction is not distribution, so no existing action covers it and the quoted prose in dalicc:additionalClauses is invisible to the compatibility checker. Proposed term: dalicc:networkUseTrigger (an odrl:Action usable as a duty, with dalicc:networkUseSourceCode for the source obligation it triggers). Patent grant, patent retaliation and the anti circumvention clause are the same gaps as in GPL-3.0-only.
info Rubric 10 family none

Apart from section 13 the model is identical to GPL-3.0-only, which is correct: the two texts differ only in sections 13 and 0. Once dalicc:networkUseTrigger exists, this record is the only one of the four that should carry it.
major Rubric 10 record applied

Standard-license addition of 2026-09-15, decision 9: the record was corrected against its new siblings and versioned. The review's finding on family consistency: the record did not carry section 4 of the text, 'You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee', which every GNU record now carries.
minor Rubric 4 odrl:prohibition applied

dalicc:promote was prohibited and no sentence of this text supports it. The statement was the library's reading of a legal default, that a copyright licence which says nothing about endorsement grants no right to it, and it sat in 519 of 581 records as a house convention. That reading is now an adopted dalicc:DefaultRule of the core dependency graph, which supplies it to every licence that is silent about the action, so a compatibility check reaches the same answer and the record states only what the text states. Removed on 2026-09-23; see section 13 of docs/LICENSE_REVIEW.md.
minor Rubric 6 dalicc:WarrantyOrLiabilityAcceptance applied

dalicc:WarrantyOrLiabilityAcceptance held the whole sentence of Section 4, "You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee." Its first half is the permission to charge for a copy, which the record states as dalicc:chargeDistributionFee, and not a warranty clause. The literal now quotes only the second half, "you may offer support or warranty protection for a fee".
major Rubric 10 dalicc:compatibleWith applied

Section 13 reads: "Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work." A work under this licence can therefore go into a combined work released under GPL-3.0; the GPL text says the same the other way round. dalicc:compatibleWith names GPL-3.0-only, GPL-3.0-or-later.

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 content review of 2026-09-15 added 1 permission and 1 statement, changed 2 identification details, recorded the relation to the record this one was adapted from and recorded the review state. Later changes brought it in line with its family and its text in the verification of 2026-09-15, corrected it against its text on 2026-09-23 and 2026-09-24, left endorsement to the default rule of the core dependency graph, recorded which sentence of the text each statement rests on, named the license the record itself is published under and recorded the licenses a work under it may be released under.

  Review finding The record carried the deprecated SPDX id "AGPL-3.0". SPDX replaced it with AGPL-3.0-only and AGPL-3.0-or-later; the record models no "any later version" option, so AGPL-3.0-only is the matching id.

Section 8 gives dalicc:terminatesOnBreach and the cure period, "you cure the violation prior to 30 days after your receipt of the notice", and section 11 of the GNU General Public License version 3, which this licence incorporates, gives the patent grant: "Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims".
