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.

677 changes with the reason "Review finding", page 2 of 14.

  • Open Government Licence - Canada version 2 2026-09-24

    changed Permission: Derivative works, with the duties Attribution, Notice

    was Permission: Derivative works, with the duties Attribution

    Review finding The licence requires two things and the record modelled one: "Acknowledge the source of the Information by including any attribution statement specified by the Information Provider(s) and, where possible, provide a link to this licence." cc:Notice was missing. Added next to cc:Attribution on the cc:DerivativeWorks and odrl:distribute permissions.

  • Open Data Commons Attribution License v1.0 version 2 2026-09-24

    added SPDX identifier: "ODC-By-1.0"

    Review finding The record carried no SPDX identifier although its title is word for word the SPDX name of ODC-By-1.0 and its cc:legalcode is the SPDX seeAlso URL. Added.

  • Open Data Commons Attribution License v1.0 version 2 2026-09-24

    changed Warranty disclaimer: "The Database is licensed by the Licensor \"as is\" and without any warranty of any kind, either express, implied, or ar...

    was Warranty disclaimer: " Open Data Commons is not a law firm and does not provide legal services of any kind. Open Data Commons has no formal r...

    Review finding dalicc:WarrantyDisclaimer did not hold a clause of the licence at all: it held the standard website disclaimer of opendatacommons.org, "Open Data Commons is not a law firm and does not provide legal services of any kind ...", which is the boilerplate printed above every licence on that site. Replaced with Section 7.1 of the licence, quoted verbatim, and Section 8.1 with 8.2 added as dalicc:LiabilityLimitation, which the record did not have.

  • Open Data Commons Attribution License v1.0 version 2 2026-09-24

    added Limitation of liability: "Subject to any liability that may not be excluded or limited by law, the Licensor is not liable for, and expressly excl...

    Review finding dalicc:WarrantyDisclaimer did not hold a clause of the licence at all: it held the standard website disclaimer of opendatacommons.org, "Open Data Commons is not a law firm and does not provide legal services of any kind ...", which is the boilerplate printed above every licence on that site. Replaced with Section 7.1 of the licence, quoted verbatim, and Section 8.1 with 8.2 added as dalicc:LiabilityLimitation, which the record did not have.

  • ODC Public Domain Dedication and Licence (PDDL) version 2 2026-09-24

    added SPDX identifier: "PDDL-1.0"

    Review finding The record carried no SPDX identifier. Its cc:legalcode, https://opendatacommons.org/licenses/pddl/1.0/, is the seeAlso URL of the SPDX entry PDDL-1.0, and the fetched document is headed "Open Data Commons Public Domain Dedication and License (PDDL) v1.0". The proposal file rated this medium; the version in the document confirms it. Added.

  • ODC Public Domain Dedication and Licence (PDDL) version 2 2026-09-24

    added Additional clauses: "Licence of Copyright and Database Rights when Sections 3.1 and 3.2 inapplicable. If the dedication and waiver in Sectio...

    Review finding Section 3.3, the licence that applies where the dedication and the waiver are ineffective, was missing. It is the operative clause in those jurisdictions and it repeats that the rights "explicitly include commercial use, and do not exclude any field of endeavour". Quoted verbatim into dalicc:additionalClauses, in the same way as the fallback clause of CC0.

  • ODC Open Database License (ODbL) version 2 2026-09-24

    added SPDX identifier: "ODbL-1.0"

    Review finding The record carried no SPDX identifier. Its cc:legalcode, https://opendatacommons.org/licenses/odbl/1.0/, is the seeAlso URL of the SPDX entry ODbL-1.0, and the fetched text is headed "Open Data Commons Open Database License (ODbL) v1.0". The proposal file rated this medium; the version in the document confirms it. Added.

  • ODC Open Database License (ODbL) version 2 2026-09-24

    added Prohibition: Promote

    Review finding dalicc:promote was missing although Section 2.3(c) states: "This License does not cover any trademarks associated with the Database." The two sibling records of the family, ODC-By and PDDL, both carry the prohibition on the identical clause. Added.

  • ODC Open Database License (ODbL) version 2 2026-09-24

    added Permission: Commercial use

    Review finding cc:CommercialUse was missing. Section 3.1: "These rights explicitly include commercial use, and do not exclude any field of endeavour." Without it the record read as if the licence were silent on commercial use, and the compatibility outcome against any NonCommercial licence was wrong. Added.

  • ODC Open Database License (ODbL) version 2 2026-09-24

    changed Title: "ODC Open Database License (ODbL)"

    was Title: "ODC Open Database License (ODbL) "

    Review finding The title literal ended with a trailing blank, "ODC Open Database License (ODbL) ". Removed.

  • Open Software License 3.0 version 2 2026-09-24

    added SPDX identifier: "OSL-3.0"

    Review finding Added OSL-3.0 and repointed dct:source, which named rosenlaw.com/OSL3.0-explained.htm, an explanatory commentary, rather than the license text.

  • Open Software License 3.0 version 2 2026-09-24

    removed Prohibition: Grant use

    Review finding Clause 1 grants a "worldwide, royalty-free, non-exclusive, sublicensable license". The record prohibited odrl:grantUse, which the text contradicts. Removed the prohibition. The matching permission was deliberately not added: the dependency graph axiom "cc:ShareAlike dalicc:contradicts odrl:grantUse" would then report a direct conflict, and this license proves the axiom is too strong, since a sublicense under the same terms is exactly what clause 1(c) requires.

  • Open Software License 3.0 version 2 2026-09-24

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

    Review finding Clause 1(c) grants the right "to distribute or communicate copies of the Original Work and Derivative Works to the public, with the proviso that copies of Original Work or Derivative Works that You distribute or communicate shall be licensed under this Open Software License". That is a duty, not a permission. Removed the cc:ShareAlike permission and added a license-wide cc:ShareAlike duty, the form the GNU and Mozilla records use.

  • Open Software License 3.0 version 2 2026-09-24

    added Duty: Share alike

    Review finding Clause 1(c) grants the right "to distribute or communicate copies of the Original Work and Derivative Works to the public, with the proviso that copies of Original Work or Derivative Works that You distribute or communicate shall be licensed under this Open Software License". That is a duty, not a permission. Removed the cc:ShareAlike permission and added a license-wide cc:ShareAlike duty, the form the GNU and Mozilla records use.

  • Open Software License 3.0 version 2 2026-09-24

    changed Source: OSL-3.0

    was Source: OSL3.0-explained.htm>

    Review finding Added OSL-3.0 and repointed dct:source, which named rosenlaw.com/OSL3.0-explained.htm, an explanatory commentary, rather than the license text.

  • Open Software License 3.0 version 2 2026-09-24

    added Limitation of liability: "Under no circumstances and under no legal theory, whether in tort (including negligence), contract, or otherwise, shall...

    Review finding Clause 8 was not recorded. Added, quoted. dalicc:WarrantyDisclaimer already held clause 7 correctly.

  • Non-Commercial Government Licence version 2 2026-09-24

    added SPDX identifier: "NCGL-UK-2.0"

    Review finding The record carried no SPDX identifier although its own DALICC identifier is the SPDX list identifier NCGL-UK-2.0 and its cc:legalcode is the SPDX seeAlso URL. Added.

  • Non-Commercial Government Licence version 2 2026-09-24

    added Prohibition: Promote

    Review finding The non-endorsement clause was not modelled: "This licence does not grant you any right to use the Information in a way that suggests any official status or that the Information Provider and/or Licensor endorse you or your use of the Information", and the exemptions list excludes logos, crests, military insignia, the Royal Arms and trade marks. The library expresses this by prohibiting dalicc:promote, which the other three government records of this review group already did. Added.

  • Non-Commercial Government Licence version 2 2026-09-24

    changed Title: "Non-Commercial Government Licence"

    was Title: "Non-Commercial Government Licence "

    Review finding The title literal ended with a trailing blank, "Non-Commercial Government Licence ". Removed.

  • Mozilla Public License Version 2.0 version 2 2026-09-24

    added SPDX identifier: "MPL-2.0"

    Review finding Added MPL-2.0.

  • Mozilla Public License Version 2.0 version 2 2026-09-24

    added Prohibition: Promote

    Review finding Section 2.3 ends: "This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be necessary to comply with the notice requirements in Section 3.4)." Added the dalicc:promote prohibition that 332 other records carry for the same clause.

  • Mozilla Public License Version 2.0 version 2 2026-09-24

    added Permission: Commercial use

    Review finding Section 2.1(a) grants a "world-wide, royalty-free, non-exclusive license ... to use, reproduce, make available, modify, display, perform, distribute, and otherwise exploit its Contributions". "Otherwise exploit" with no field-of-use limit is a commercial grant, and section 3.2 contemplates charging for a distribution. The record did not permit cc:CommercialUse, which made a widely used permissive-leaning copyleft license look non-commercial. Added.

  • Microsoft Public License version 2 2026-09-24

    added SPDX identifier: "MS-PL"

    Review finding Added MS-PL; the title matches the SPDX name exactly.

  • Microsoft Public License version 2 2026-09-24

    added Warranty disclaimer: "(E) The software is licensed \"as-is.\" You bear the risk of using it. The contributors give no express warranties, gua...

    Review finding Condition 3(E) is a warranty disclaimer and was not recorded. Added, quoted.

  • The MIT License version 2 2026-09-24

    added SPDX identifier: "MIT"

    Review finding The record id is the SPDX list id but the field was absent. Added.

  • The MIT License version 2 2026-09-24

    added Permission: Grant use

    Review finding The grant reads: "to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software". Sublicensing (odrl:grantUse) and charging for a copy (dalicc:chargeDistributionFee) were not modelled. Added both.

  • The MIT License version 2 2026-09-24

    added Permission: Charge distribution fee

    Review finding The grant reads: "to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software". Sublicensing (odrl:grantUse) and charging for a copy (dalicc:chargeDistributionFee) were not modelled. Added both.

  • LaTeX Project Public License, Version 1.3c version 2 2026-09-24

    added SPDX identifier: "LPPL-1.3c"

    Review finding 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.

  • LaTeX Project Public License, Version 1.3c version 2 2026-09-24

    removed Prohibition: Derive

    Review finding 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.

  • LaTeX Project Public License, Version 1.3c version 2 2026-09-24

    removed Prohibition: Derivative works

    Review finding 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.

  • LaTeX Project Public License, Version 1.3c version 2 2026-09-24

    added Permission: Derive, with the duties Source code, Modification notice

    Review finding 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.

  • LaTeX Project Public License, Version 1.3c version 2 2026-09-24

    added Permission: Modified works

    Review finding 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.

  • LaTeX Project Public License, Version 1.3c version 2 2026-09-24

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

    Review finding 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.

  • LaTeX Project Public License, Version 1.3c version 2 2026-09-24

    added Permission: Derivative works

    Review finding 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.

  • LaTeX Project Public License, Version 1.3c version 2 2026-09-24

    added Source: LPPL-1.3c

    Review finding 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.

  • GNU Lesser General Public License version 3.0 version 2 2026-09-24

    added SPDX identifier: "LGPL-3.0-only"

    Review finding Added the SPDX list id LGPL-3.0-only.

  • GNU Lesser General Public License version 3.0 version 2 2026-09-24

    added Permission: Charge distribution fee

    Review finding 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.

  • ISC License version 2 2026-09-24

    added SPDX identifier: "ISC"

    Review finding Added the SPDX list id ISC.

  • ISC License version 2 2026-09-24

    changed Permission: Modify, with the duties Attribution, Notice

    was Permission: Modify, with the duties Attribution

    Review finding The condition reads: "provided that the above copyright notice and this permission notice appear in all copies". The record required cc:Attribution only. Added cc:Notice to the distribute, modify and derive duties, matching MIT and the BSD records.

  • ISC License version 2 2026-09-24

    changed Permission: Distribute, with the duties Attribution, Notice

    was Permission: Distribute, with the duties Attribution

    Review finding The condition reads: "provided that the above copyright notice and this permission notice appear in all copies". The record required cc:Attribution only. Added cc:Notice to the distribute, modify and derive duties, matching MIT and the BSD records.

  • ISC License version 2 2026-09-24

    changed Permission: Derive, with the duties Attribution, Notice

    was Permission: Derive, with the duties Attribution

    Review finding The condition reads: "provided that the above copyright notice and this permission notice appear in all copies". The record required cc:Attribution only. Added cc:Notice to the distribute, modify and derive duties, matching MIT and the BSD records.

  • ISC License version 2 2026-09-24

    added Permission: Charge license fee

    Review finding The grant is "for any purpose with or without fee". dalicc:chargeDistributionFee was already permitted; added dalicc:chargeLicenseFee so that the record says the same as 0BSD, whose text is this text minus the notice condition.

  • INSPIRE End User Licence version 2 2026-09-24

    added Duty: Notice

    Review finding The record carried no duty of any kind and was the single violation of rule 6 of the family-rule baseline, every record needs an attribution or notice duty. The licence has one, clause 3.1: "You shall not alter or remove any of the OS copyright / database right notices and licence numbers which are shown on the Supplied Data." A licence-wide cc:Notice duty was added, licence-wide because the duty is owed for any use and the acts that would normally carry it, distribution and public display, are prohibited here.

  • INSPIRE End User Licence version 2 2026-09-24

    changed Source: Inspire-licence.html>

    was Source: Inspire-licence.html>

    Review finding cc:legalcode and dct:source both pointed at an Ordnance Survey URL that returns 404, and the current site has no INSPIRE licence page, so the record had no working link to its text. dct:source now points at the Internet Archive snapshot of 30 March 2019, which is the text that was read for this review. cc:legalcode was left at the original URL, because it is the address the licence was published at and changing it would erase that fact; it is to be replaced once Ordnance Survey republishes the licence.

  • GNU Free Documentation License version 1.3 version 2 2026-09-24

    added SPDX identifier: "GFDL-1.3-only"

    Review finding The title names version 1.3 and the fetched legal code is fdl-1.3. SPDX splits the license into GFDL-1.3-only and GFDL-1.3-or-later; the record models no "or any later version" option, so the "-only" id was added.

  • GNU Free Documentation License version 1.3 version 2 2026-09-24

    removed Prohibition: Charge distribution fee

    Review finding Section 2 states: "you may accept compensation in exchange for copies". The record prohibited dalicc:chargeDistributionFee, which contradicts the text and would make every paid documentation reprint look unlicensed. Removed the prohibition and added the permission.

  • GNU Free Documentation License version 1.3 version 2 2026-09-24

    added Permission: Charge distribution fee

    Review finding Section 2 states: "you may accept compensation in exchange for copies". The record prohibited dalicc:chargeDistributionFee, which contradicts the text and would make every paid documentation reprint look unlicensed. Removed the prohibition and added the permission.

  • GNU General Public License 3 version 2 2026-09-24

    added SPDX identifier: "GPL-3.0-only"

    Review finding Added the SPDX list id GPL-3.0-only.

  • GNU General Public License 3 version 2 2026-09-24

    added Permission: Charge distribution fee

    Review finding Section 4 states: "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." Added the missing dalicc:chargeDistributionFee permission.

  • GNU General Public License 3 version 2 2026-09-24

    changed Source: Gpl-3.0.html>

    was Source: Gpl.html>

    Review finding Added the SPDX list id GPL-3.0-only.
