Changes to the license models

What DALICC changed in its curated models, when, and why.

A license model is corrected when a reading of the legal text turns out to be wrong. Every correction changes what the compatibility checker answers, so each change below names the reason behind it and links to the record it was made on.

  • The zlib libpng License version 2 2026-09-24

    added SPDX identifier: "Zlib"

    Review finding Added Zlib. Verified rather than taken on trust: cc:legalcode already points at the Open Source Initiative page that the SPDX entry lists under seeAlso, and the fetched text is the same three-restriction license.

  • The zlib libpng License version 2 2026-09-24

    changed Permission: Modify, with the duties Notice, Modification notice, Rename

    was Permission: Modify, with the duties Notice, Modification notice, Rename

    Manual edit Its duty dalicc:modificationNotice quotes "Altered source versions must be plainly marked as such, and must not be misrepresented as being the original software."

  • The zlib libpng License version 2 2026-09-24

    changed Permission: Derive, with the duties Notice, Modification notice, Rename

    was Permission: Derive, with the duties Notice, Modification notice, Rename

    Manual edit Its duty dalicc:modificationNotice quotes "Altered source versions must be plainly marked as such, and must not be misrepresented as being the original software."

  • The zlib libpng License version 2 2026-09-24

    added Permission: Change license, with the duties Use a compliant license

    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 is granted to anyone to use this software for any purpose, including commercial applications, and to alter it and redistribute it freely, subject to the following restrictions: 1. The origin of this software must not be misrepresented; you must not claim that you wrote the original software." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.

  • The zlib libpng License version 2 2026-09-24

    changed Permission: Change license, with the duties Use a compliant license

    was Permission: Change license, with the duties Use a compliant license

    Manual edit The statement is marked as a library convention, family rule 15: Permissive records permit relicensing: the text does not state it in as many words. Its duty dalicc:compliantLicense is marked as a library convention, family rule 15: Permissive records permit relicensing.

  • The zlib libpng License version 2 2026-09-24

    removed Publisher: "N.N."

    Manual edit Library conventions 10 and 14: the disclaimer held both sentences of the zlib notice, the second beginning 'In no event will the authors be held liable for any damages arising from the use of this software', and dct:publisher was the placeholder 'N.N.'.

  • The zlib libpng License version 2 2026-09-24

    added License: >

    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.

  • The zlib libpng License version 2 2026-09-24

    removed Alternative name: "Libpng"

    Manual edit The alternative name "Libpng" is dropped. The SPDX license list gives that identifier to a different text, the libpng notice, which the library now holds as the record Libpng, so a lookup for the name reached the wrong licence.

  • The zlib libpng License version 2 2026-09-24

    added Reviewed on: "2026-09-15"

    Review state Every record records how far it has come in the editorial workflow and when it was last checked against the legal text.

  • The zlib libpng License version 2 2026-09-24

    added Review status: Reviewed

    Review state Every record records how far it has come in the editorial workflow and when it was last checked against the legal text.

  • The zlib libpng License version 2 2026-09-24

    changed Warranty disclaimer: "This software is provided ‘as-is’, without any express or implied warranty."

    was Warranty disclaimer: "This software is provided ‘as-is’, without any express or implied warranty. In no event will the authors be held liable...

    Manual edit Library conventions 10 and 14: the disclaimer held both sentences of the zlib notice, the second beginning 'In no event will the authors be held liable for any damages arising from the use of this software', and dct:publisher was the placeholder 'N.N.'.

  • The zlib libpng License version 2 2026-09-24

    added Warranty disclaimer: "This software is provided ‘as-is’, without any express or implied warranty. In no event will the authors be held liable...

    Review finding The opening paragraph is a warranty disclaimer and was not recorded. Added, quoted from the text.

  • The zlib libpng License version 2 2026-09-24

    added Limitation of liability: "In no event will the authors be held liable for any damages arising from the use of this software."

    Manual edit Library conventions 10 and 14: the disclaimer held both sentences of the zlib notice, the second beginning 'In no event will the authors be held liable for any damages arising from the use of this software', and dct:publisher was the placeholder 'N.N.'.

  • The Universal Permissive License (UPL), Version 1.0 version 2 2026-09-24

    added SPDX identifier: "UPL-1.0"

    Review finding Added UPL-1.0. The record title, dct:alternative and dct:source (the Open Source Initiative page for UPL) all agree with the SPDX entry.

  • The Universal Permissive License (UPL), Version 1.0 version 2 2026-09-24

    removed Prohibition: Promote

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

  • The Universal Permissive License (UPL), Version 1.0 version 2 2026-09-24

    removed Prohibition: Share alike

    Review finding The grant ends "and to sublicense the foregoing rights on either these or other terms", so relicensing under this same license is expressly allowed. Prohibiting cc:ShareAlike asserted the opposite. cc:ShareAlike is a duty term and a permissive license that is silent about reciprocity must carry no share-alike statement at all. Removed. Flagged by the family conventions checked before the review.

  • The Universal Permissive License (UPL), Version 1.0 version 2 2026-09-24

    added Permission: Change license, with the duties Use a compliant license

    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: "This license is subject to the following condition: The above copyright notice and either this complete permission notice or at a minimum a reference to the UPL must be included in all copies or substantial portions of the Software." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.

  • The Universal Permissive License (UPL), Version 1.0 version 2 2026-09-24

    changed Permission: Change license, with the duties Use a compliant license

    was Permission: Change license, with the duties Use a compliant license

  • The Universal Permissive License (UPL), Version 1.0 version 2 2026-09-24

    removed Publisher: "- not specified -"

    Manual edit Library conventions 10 and 14: the disclaimer paragraph held the liability sentence, which begins 'IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE', and dct:publisher and cc:attributionName were the placeholder '- not specified -'.

  • The Universal Permissive License (UPL), Version 1.0 version 2 2026-09-24

  • Sustainable Use License version 2 2026-09-24

    changed Prohibition: Exempted material

  • Sustainable Use License version 2 2026-09-24

    changed Prohibition: Change license

    was Prohibition: Change license

    Manual edit Removed the quoted evidence of prohibition dalicc:ChangeLicense: the quoted sentence does not name the act. The statements stay, read from the text without a linked quote.

  • Sustainable Use License version 2 2026-09-24

    changed Permission: Reproduce

    was Permission: Reproduce

    Manual edit The statement now quotes the sentence of the licence text it rests on: "The licensor grants you a non-exclusive, royalty-free, worldwide, non-sublicensable, non-transferable license to use, copy, distribute, make available, and prepare derivative works of the software, in each case subject to the limitations below."

  • Sustainable Use License version 2 2026-09-24

  • SUN PUBLIC LICENSE Version 1.0 version 2 2026-09-24

    added SPDX identifier: "SPL-1.0"

    Review finding Added SPL-1.0. Verified rather than assumed: cc:legalcode and dct:source already point at the Open Source Initiative page for SPL-1.0 and the fetched text is the Sun Public License version 1.0.

  • SUN PUBLIC LICENSE Version 1.0 version 2 2026-09-24

    removed Prohibition: Grant use

    Review finding Sections 2.1(b) and 2.2(b) grant the right to "use, reproduce, modify, display, perform, sublicense and distribute the Original Code (or portions thereof) with or without Modifications". The record prohibited odrl:grantUse. Removed the prohibition; the matching permission is held back by the same dependency-graph axiom as in OSL-3.0.

  • SUN PUBLIC LICENSE Version 1.0 version 2 2026-09-24

    removed Permission: Share alike, with the duties Notice, Source code

    Review finding Section 3.1 states that "The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2." That is a duty. Removed the cc:ShareAlike permission and added a license-wide cc:ShareAlike duty.

  • SUN PUBLIC LICENSE Version 1.0 version 2 2026-09-24

  • Statistics Canada Open Licence Agreement version 2 2026-09-24

    removed Prohibition: Modify

    Review finding odrl:derive and odrl:modify were modelled as prohibitions, which contradicts the grant. The Licence Grant section reads: "Statistics Canada grants you a worldwide, royalty-free, non-exclusive licence to: use, reproduce, publish, freely distribute, or sell the Information; use, reproduce, publish, freely distribute, or sell Value-added Products; and, sublicence any or all such rights, under terms consistent with this licence", and Value-added Products are defined as "any products you have produced by adapting or incorporating the Information, in whole or in part, in accordance with this licence". The two prohibitions were removed and the corresponding permissions added, together with cc:DerivativeWorks and dalicc:ModifiedWorks, since publishing, distributing and selling Value-added Products is expressly granted.
