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 removed 1 prohibition and recorded the review state. Later changes brought it in line with its family and its text in the verification of 2026-09-15, left endorsement to the default rule of the core dependency graph and named the license the record itself is published under.

    7 changes

    • 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.

    • removed prohibition cc:ShareAlike

      Review finding Section 3.2 states that an Executable Distribution may be made "under the terms of Section 2 of this License, provided the Executable Distribution is made available under and accompanied by a copy of this License". The record prohibited cc:ShareAlike, which reverses the license. Removed.

    • changed cc:attributionName "- not specified -"

      was cc:attributionName "- not specified - "

      Manual edit Library convention 14: the warranty and liability literals carried a padding space inside their quotation marks.

    • changed dct:publisher "- not specified -"

      was dct:publisher "- not specified - "

      Manual edit Library convention 14: the warranty and liability literals carried a padding space inside their quotation marks.

    • 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.

  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.
