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 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.

    8 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.

    • added dalicc:LiabilityLimitation "IN NO EVENT SHALL THE AUTHOR OR ANY CONTRIBUTOR BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO, EFFECTS OF UNAUTHORIZED OR MALICIOUS NETWORK ACCESS; PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE."

      Manual edit Library convention 10: the disclaimer paragraph held both the warranty sentence and the liability sentence, which begins 'IN NO EVENT SHALL THE AUTHOR OR ANY CONTRIBUTOR BE LIABLE'. It is split, as the 116 records of the standard-license addition split it.

    • changed dalicc:WarrantyDisclaimer "THIS FREE SOFTWARE IS PROVIDED BY THE AUTHOR \"AS IS\" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED."

      was dalicc:WarrantyDisclaimer "THIS FREE SOFTWARE IS PROVIDED BY THE AUTHOR \"AS IS\" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

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.
