Prohibitions

This license states no prohibitions.

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)

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: 6 recorded, 3 applied to the record, 0 proposed, 1 settled in a later version

The record models the Zero Clause BSD license, which grants use, copying, modification and distribution "for any purpose with or without fee" and attaches no condition at all. Twelve permissions and no duties is the right shape. The record prohibited cc:ShareAlike, which the text contradicts; that prohibition was removed.

5 findings

major Rubric 5 odrl:prohibition applied

The text reads in full: "Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted." A prohibition of cc:ShareAlike asserts that a licensee may not put the work out under these same terms, which the unconditional grant contradicts. cc:ShareAlike is a duty term; a license that is silent about relicensing must carry no share-alike statement at all. Removed. Flagged by the family conventions checked before the review.
info Rubric 5 odrl:duty none

The record carries no duty. That is correct and it is the only member of the BSD family for which it is correct: the Zero Clause BSD license is the ISC license with the copyright-notice condition struck out. The note in the family conventions checked before the review that "0BSD ... require the notice to be kept" is wrong.
info Rubric 1 dct:title none

The title "Free Public License 1.0.0" is the name the Open Source Initiative uses for this text; SPDX calls it "BSD Zero Clause License". Both spellings are in dct:alternative and cc:legalcode points at the OSI page, so the record is findable under either name.
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 permitted dalicc:noWarrantyNotice and prohibited dalicc:addStatement, neither of which the Zero Clause BSD text states, and carried the placeholder '- not specified - ' as its publisher and attribution name. The whole operative text is 'Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted.' The disclaimer paragraph is split at 'IN NO EVENT SHALL THE AUTHOR 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.

Settled in version 2 (1)

settled odrl:prohibition

dalicc:addStatement and dalicc:promote remain prohibited although the text says nothing about additional notices or trademarks. They are the library-wide default and were left alone, but neither is text-supported here.

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 removed 1 prohibition, 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, permitted relicensing with the notice as a duty, 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.

- added permission dalicc:ChangeLicense
  
  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/or distribute this software for any purpose with or without fee is hereby granted." The permission carries no duty, as on the public-domain dedications, because nothing has to travel with the copy.

  Manual edit The endorsement prohibition rested on no sentence of the text; the default rule for endorsement now supplies it.

  Manual edit Every record is published under CC BY 4.0. cc:license names the record DALICC keeps of that licence; dct:license now names it by the address Creative Commons publishes it at, so that a consumer matching the canonical IRI finds it.
