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.

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)

Clauses

Warranty disclaimer

There is no warranty for the Work. Except when otherwise stated in writing, the Copyright Holder provides the Work `as is', without warranty of any kind, either expressed or implied, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose. The entire risk as to the quality and performance of the Work is with you. Should the Work prove defective, you assume the cost of all necessary servicing, repair, or correction.

Limitation of liability

In no event unless required by applicable law or agreed to in writing will The Copyright Holder, or any author named in the components of the Work, or any other party who may distribute and/or modify the Work as permitted above, be liable to you for damages, including any general, special, incidental or consequential damages arising out of any use of the Work or out of inability to use the Work (including, but not limited to, loss of data, data being rendered inaccurate, or losses sustained by anyone as a result of any failure of the Work to operate with any other programs), even if the Copyright Holder or said author or said other party has been advised of the possibility of such damages.

Accepting warranty or additional liability

The Work has the status `author-maintained' if the Copyright Holder explicitly and prominently states near the primary copyright notice in the Work that the Work can only be maintained by the Copyright Holder or simply that it is `author-maintained'. The Work has the status `maintained' if there is a Current Maintainer who has indicated in the Work that they are willing to receive error reports for the Work (for example, by supplying a valid e-mail address). It is not required for the Current Maintainer to acknowledge or act upon these error reports. The Work changes from status `maintained' to `unmaintained' if there is no Current Maintainer, or the person stated to be Current Maintainer of the work cannot be reached through the indicated means of communication for a period of six months, and there are no other significant signs of active maintenance. You can become the Current Maintainer of the Work by agreement with any existing Current Maintainer to take over this role. If the Work is unmaintained, you can become the Current Maintainer of the Work through the following steps: Make a reasonable attempt to trace the Current Maintainer (and the Copyright Holder, if the two differ) through the means of an Internet or similar search. If this search is successful, then enquire whether the Work is still maintained. If it is being maintained, then ask the Current Maintainer to update their communication data within one month. If the search is unsuccessful or no action to resume active maintenance is taken by the Current Maintainer, then announce within the pertinent community your intention to take over maintenance. (If the Work is a LaTeX work, this could be done, for example, by posting to comp.text.tex.) If the Current Maintainer is reachable and agrees to pass maintenance of the Work to you, then this takes effect immediately upon announcement. If the Current Maintainer is not reachable and the Copyright Holder agrees that maintenance of the Work be passed to you, then this takes effect immediately upon announcement. If you make an `intention announcement' as described in 2b. above and after three months your intention is challenged neither by the Current Maintainer nor by the Copyright Holder nor by other people, then you may arrange for the Work to be changed so as to name you as the (new) Current Maintainer. If the previously unreachable Current Maintainer becomes reachable once more within three months of a change completed under the terms of 3b) or 4), then that Current Maintainer must become or remain the Current Maintainer upon request provided they then update their communication data within one month. A change in the Current Maintainer does not, of itself, alter the fact that the Work is distributed under the LPPL license. If you become the Current Maintainer of the Work, you should immediately provide, within the Work, a prominent and unambiguous statement of your status as Current Maintainer. You should also announce your new status to the same pertinent community as in 2b) above.

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: 8 recorded, 5 applied to the record, 2 proposed

The LaTeX Project Public License lets anyone modify the Work and distribute the Derived Work, provided every component carries a change notice, replacement components identify themselves as modified, and the unmodified Work stays obtainable. The record prohibited derivative works outright, which reverses clauses 5 and 6. Those prohibitions were replaced by the permissions and duties the text sets, and the clause 10 right to relicense a Derived Work was added.

8 findings

major Rubric 3 odrl:prohibition applied

Clause 5 states: "If you are not the Current Maintainer of the Work, you may modify your copy of the Work, thus creating a Derived Work", and clause 6 then sets out how a Derived Work may be distributed. The record prohibited odrl:derive and cc:DerivativeWorks, so a compatibility check treated every LaTeX package fork as forbidden. Removed both and added the permissions with the duties of clause 6.
major Rubric 3 odrl:permission applied

Clause 10(a) states: "A Derived Work may be distributed under a different license provided that license itself honors the conditions listed in Clause 6 above". That is dalicc:ChangeLicense with a dalicc:compliantLicense duty. Added.
minor Rubric 1 spdx:licenseId applied

Added LPPL-1.3c and the missing dct:source. Verified rather than assumed: cc:legalcode already points at the Open Source Initiative page that the SPDX entry lists under seeAlso, and the fetched text is version 1.3c.
major Rubric 5 odrl:duty proposed

Clause 6(a) requires a replacement component to "clearly and unambiguously identify itself as a modified version of this component to the user when used interactively". That is dalicc:rename plus a runtime identification the vocabulary cannot express. The rename half could be added; it is proposed because clause 6(a) is about runtime identification rather than the file name.
minor Rubric 4 odrl:prohibition proposed

cc:ShareAlike is prohibited although clause 10(a) allows a different license and nothing forbids using this one. dalicc:promote is prohibited although the license has no trademark clause; clause 6(c) is about not implying that the original authors provide support.
gap Rubric 8 vocabulary none

The Current Maintainer construction, which gives one party rights that everyone else lacks (clause 4 versus clauses 5 to 7), cannot be expressed: the model has one assignee. Proposed term: dalicc:maintainerRole. Clause 6(a) runtime identification is a second gap.
minor Rubric 10 record applied

Standard-license addition of 2026-09-15, decision 9 and 10: the record was corrected against its new siblings and versioned. Library convention 10: the disclaimer paragraph held the liability sentence, which begins 'IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL THE COPYRIGHT HOLDER ... BE LIABLE'.
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.

Report an issue The review record as JSON The review checks the model against the license text. It is not legal advice.

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 2 identification details and 4 permissions, removed 2 prohibitions 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, left endorsement to the default rule of the core dependency graph, recorded which sentence of the text each statement rests on and named the license the record itself is published under.
