Clauses

Warranty disclaimer

The Work is provided by the Rightsholder “as is” and without any warranty of any kind, either express or implied, whether of title, of accuracy or completeness, of the presence of absence of errors, of fitness for purpose, or otherwise. Some jurisdictions do not allow the exclusion of implied warranties, so this exclusion may not apply to You.

Limitation of liability

Subject to any liability that may not be excluded or limited by law, the Rightsholder is not liable for, and expressly excludes, all liability for loss or damage however and whenever caused to anyone by any use under this Document, whether by You or by anyone else, and whether caused by any fault on the part of the Rightsholder or not. This exclusion of liability includes, but is not limited to, any special, incidental, consequential, punitive, or exemplary damages. This exclusion applies even if the Rightsholder has been advised of the possibility of such damages. If liability may not be excluded by law, it is limited to actual and direct financial loss to the extent it is caused by proved negligence on the part of the Rightsholder.

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.

  1. Version 2 current2026-09-24 Giray Havur

    The content review of 2026-09-15 added 1 clause text and 1 identification detail and recorded the review state. Later changes brought it in line with its family and its text in the verification of 2026-09-15, recorded which sentence of the text each statement rests on, recorded what the text says about the database right, named the license the record itself is published under and left endorsement to the default rule of the core dependency graph.

    • added dalicc:additionalClauses "Licence of Copyright and Database Rights when Sections 3.1 and 3.2 inapplicable. If the dedication and waiver in Sections 3.1 and 3.2 does not apply in the relevant jurisdiction under Section 6.4, the Rightsholder and You agree as follows: The Licensor grants to You a worldwide, royalty-free, non-exclusive, licence to Use the Work for the duration of any applicable Copyright and Database Rights. These rights explicitly include commercial use, and do not exclude any field of endeavour."

      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.

    • added dalicc:reviewStatus dalicc: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.

    • added dalicc:reviewedOn "2026-09-15"^^xsd:date

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

    • added spdx:licenseId "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.

    • changed dalicc:WarrantyDisclaimer "The Work is provided by the Rightsholder “as is” and without any warranty of any kind, either express or implied, whether of title, of accuracy or completeness, of the presence of absence of errors, of fitness for purpose, or otherwise. Some jurisdictions do not allow the exclusion of implied warranties, so this exclusion may not apply to You."

      was dalicc:WarrantyDisclaimer " The Work is provided by the Rightsholder “as is” and without any warranty of any kind, either express or implied, whether of title, of accuracy or completeness, of the presence of absence of errors, of fitness for purpose, or otherwise. Some jurisdictions do not allow the exclusion of implied warranties, so this exclusion may not apply to You."

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

    • changed permission dalicc:ChangeLicense

      was permission dalicc:ChangeLicense

      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.

    • added permission dalicc:suiGenerisDatabaseRights

      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.

    • added dct:license <https://creativecommons.org/licenses/by/4.0/>

      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.

    • removed prohibition dalicc:promote

      Manual edit No sentence was quoted for the prohibition. The text only says "This Document does not cover any trade marks associated with the Database." (Section 2.2(c)), which is silence about endorsement, and the default rule of the core dependency graph covers silence.

  2. Version 1

    The version this model had before the content review of 2026-09-15.

Every change names the reason behind it: a finding of the content review, one of its library-wide decisions, the metadata that review wrote onto every record, or a hand edit. None of it is legal advice.

Nothing on this page is legal advice. What a license means is decided by its text; ask a legal advisor before you rely on it.
