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 permission, changed 2 permissions, recorded the relation to the record this one was adapted from 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 and named the license the record itself is published under.

      Review finding Section 4(a) reads: "You must give any other recipients of the Work or Derivative Works a copy of this License".

    • added permission odrl:grantUse

      Review finding Section 2 grants a "perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare Derivative Works of, publicly display, publicly perform, sublicense, and distribute the Work". Sublicensing was not modelled. Added odrl:grantUse.

    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.
