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) Using the name or trademarks of the licensor or of contributors to endorse or promote a product.

    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.

Accepting warranty or additional liability

you may offer support or warranty protection for a fee

Additional clauses

You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.

Findings
9 recorded, 6 applied to the record, 2 proposed

The record is a byte-for-byte copy of the GPL-3.0-only model: the same permissions, the same license-wide share-alike duty, the same prohibition on changing the license. The one thing that distinguishes the Lesser GPL from the GPL, the right to convey a Combined Work under terms of your choice, only appears as prose in dalicc:additionalClauses and not as a modelled permission. That is the main open issue.

9 findings

  • minor Rubric 1 spdx:licenseId applied

    Added the SPDX list id LGPL-3.0-only.

  • major Rubric 3 odrl:permission applied

    Section 4 of the GPL, which the Lesser GPL incorporates, states: "You may charge any price or no price for each copy that you convey." Added the missing dalicc:chargeDistributionFee permission.

  • major Rubric 10 odrl:prohibition proposed

    Section 4 states: "You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work." The record prohibits dalicc:ChangeLicense exactly as GPL-3.0-only does, so the weak copyleft of the Lesser GPL is not distinguishable from the strong copyleft of the GPL in any compatibility result. The text of section 4 is already quoted in dalicc:additionalClauses. Interpretive, so left open for the association's decision.

  • minor Rubric 6 dalicc:WarrantyDisclaimer proposed

    The record carries no warranty disclaimer and no liability limitation. The Lesser GPL has none of its own: sections 15 and 16 of the GPL apply through section 4 of the Lesser GPL. Copying the GPL text into this record would quote a different document, so it is proposed rather than applied.

  • gap Rubric 8 vocabulary none

    Section 4(d)(0) and 4(e), the "suitable shared library mechanism" and installation information duties that make relinking possible, have no vocabulary term. Proposed term: dalicc:relinkingInformation. Patent grant and patent retaliation inherited from the GPL are gaps too.

  • 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 carried neither a warranty disclaimer nor a liability limitation although 'This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License', whose sections 15 and 16 are the two clauses, and it did not carry section 4 of that text either.

  • 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 2 lets a modified version of the Library be conveyed "under the GNU GPL, with none of the additional permissions of this License applicable to that copy." The GNU GPL is version 3 of it or, where the Library says so, any later version. 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.

  1. Version 2 current2026-09-24 Giray Havur

    The content review of 2026-09-15 added 1 identification detail, 1 permission and 1 statement, 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.

Variants

2 records in the library model this same legal text with one thing changed: the option of a later version, an exception that lifts one condition, or a rider that adds one. Each of them is a license of its own and is listed like any other. See variant in the glossary.
