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 left endorsement to the default rule of the core dependency graph and named the license the record itself is published under.

    • added dalicc:LiabilityLimitation "In no event shall the initial developers or copyright holders be liable for any damages whatsoever, including - but not restricted to - lost revenue or profits or other direct, indirect, special, incidental or consequential damages, even if they have been advised of the possibility of such damages, except to the extent invariable law, if any, provides otherwise."

      Review finding The section headed "Limitations of Liability" was not recorded. Added, quoted.

    • added dalicc:reviewStatus dalicc:Reviewed

    • added spdx:licenseId "QPL-1.0"

      Review finding Added QPL-1.0; the title matches the SPDX name.

    • removed prohibition dalicc:promote

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

    • 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.

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.
