Changes to the license models

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

added Permission: Extract or reuse a substantial part of a database

Manual edit Section 3.3(a), the licence that applies where the dedication and waiver of Sections 3.1 and 3.2 do not, grants the rights "for the duration of any applicable copyright and Database Rights", and the licence defines Database Rights as the sui generis right of the Database Directive, so the permission is text-supported.

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

changed Permission: Change license

was Permission: Change 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.

ODC Public Domain Dedication and Licence (PDDL) 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.

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

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

Manual edit Library convention 14: the warranty literal carried a padding space inside its quotation marks.

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: Sublicense

Review decision Review decision 1: every Creative Commons record except the CC0 dedication, plus the Open Database License and the Open Data Commons Attribution License, forbids sublicensing in as many words.

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

changed Prohibition: Sublicense

was Prohibition: Sublicense

Manual edit The statement now quotes the sentence of the licence text it rests on: "You may not sublicense the Database."

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

changed Prohibition: Promote

was Prohibition: Promote

Manual edit The statement now quotes the sentence of the licence text it rests on: "This License does not cover any trademarks associated with the Database."

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

removed Prohibition: Promote

Manual edit The sentence the prohibition rested on, "This License does not cover any trademarks associated with the Database.", is silence about endorsement, which the default rule of the core dependency graph covers.

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

removed Prohibition: Charge distribution fee

Manual edit The review's finding on family consistency: the record prohibited dalicc:chargeDistributionFee although the ODbL nowhere forbids charging for a copy. What it does is cap the price of the copy that has to accompany a Restricted Database and of the derivative database file, and those two sentences are now quoted instead; dct:source was missing.

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

changed Permission: Modify, with the duties Attribution, Notice

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

Manual edit No sentence of the text asks for a notice of changes; the alteration file of Section 4.6(b) is an alternative way to give access to a Derivative Database.

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

changed Permission: Derive, with the duties Attribution, Notice

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

Manual edit No sentence of the text asks for a notice of changes; the alteration file of Section 4.6(b) is an alternative way to give access to a Derivative Database.

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

added Permission: Extract or reuse a substantial part of a database, with the duties Attribution, Notice

Manual edit Section 3.1 grants the rights "for the duration of any applicable copyright and Database Rights", and the licence defines Database Rights as the sui generis right of the Database Directive, so the permission is text-supported. The attribution and notice conditions of Section 4 apply to it as they apply to every use of the Database.

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 Permission: Commercial use

was Permission: Commercial use

Manual edit The statement now quotes the sentence of the licence text it rests on: "These rights explicitly include commercial use, and do not exclude any field of endeavour."

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.

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

added Source: >

Manual edit The review's finding on family consistency: the record prohibited dalicc:chargeDistributionFee although the ODbL nowhere forbids charging for a copy. What it does is cap the price of the copy that has to accompany a Restricted Database and of the derivative database file, and those two sentences are now quoted instead; dct:source was missing.

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

changed Publisher: "Open Data Commons (Open Knowledge Foundation)"

was Publisher: "Socialtext Incorporated"

Manual edit The ODbL is published by Open Data Commons, a project of the Open Knowledge Foundation; the earlier value named the publisher of another licence.

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

added Prohibition: Patent license ends on a patent claim

Manual edit The review's finding on family consistency and consolidation decision 4: the record permitted dalicc:noWarrantyNotice and prohibited dalicc:addStatement without support, made no patent statement although section 2 grants one and section 10 ends it on patent litigation, and said nothing about relicensing although clause 1(c) requires every copy to be 'licensed under this License', which the four new Open Software License records model as a dalicc:ChangeLicense prohibition.

Open Software License 3.0 version 2 2026-09-24

removed Prohibition: Add statement

Open Software License 3.0 version 2 2026-09-24

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.
