    21 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 permission dalicc:chargeLicenseFee

      Review finding The grant is "for any purpose with or without fee". dalicc:chargeDistributionFee was already permitted; added dalicc:chargeLicenseFee so that the record says the same as 0BSD, whose text is this text minus the notice condition.

    • changed permission odrl:derive with duties [cc:Attribution, cc:Notice]

      was permission odrl:derive with duties [cc:Attribution]

      Review finding The condition reads: "provided that the above copyright notice and this permission notice appear in all copies". The record required cc:Attribution only. Added cc:Notice to the distribute, modify and derive duties, matching MIT and the BSD records.

    • changed permission odrl:distribute with duties [cc:Attribution, cc:Notice]

      was permission odrl:distribute with duties [cc:Attribution]

      Review finding The condition reads: "provided that the above copyright notice and this permission notice appear in all copies". The record required cc:Attribution only. Added cc:Notice to the distribute, modify and derive duties, matching MIT and the BSD records.

    • changed permission odrl:modify with duties [cc:Attribution, cc:Notice]

      was permission odrl:modify with duties [cc:Attribution]

      Review finding The condition reads: "provided that the above copyright notice and this permission notice appear in all copies". The record required cc:Attribution only. Added cc:Notice to the distribute, modify and derive duties, matching MIT and the BSD records.

    • added spdx:licenseId "ISC"

      Review finding Added the SPDX list id ISC.

    • added dalicc:LiabilityLimitation "IN NO EVENT SHALL THE AUTHOR BE LIABLE FOR ANY SPECIAL, DIRECT, INDIRECT, OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, WHETHER IN AN ACTION OF CONTRACT, NEGLIGENCE OR OTHER TORTIOUS ACTION, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE."

      Manual edit The review's finding on family consistency: dct:publisher was the placeholder 'N.N.'; the ISC text names no steward, so the predicate is left out rather than filled with a placeholder. The disclaimer paragraph is split at 'IN NO EVENT SHALL THE AUTHOR BE LIABLE', the split the new ISC-form records use.

    • changed dalicc:WarrantyDisclaimer "THE SOFTWARE IS PROVIDED \"AS IS\" AND THE AUTHOR DISCLAIMS ALL WARRANTIES WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS."

      was dalicc:WarrantyDisclaimer "THE SOFTWARE IS PROVIDED \"AS IS\" AND THE AUTHOR DISCLAIMS ALL WARRANTIES WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS. IN NO EVENT SHALL THE AUTHOR BE LIABLE FOR ANY SPECIAL, DIRECT, INDIRECT, OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, WHETHER IN AN ACTION OF CONTRACT, NEGLIGENCE OR OTHER TORTIOUS ACTION, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE."

    • removed dct:publisher "N.N."

    • added permission dalicc:ChangeLicense with duties [dalicc:compliantLicense]

      Manual edit Permit relicensing on permissive licences; the notice clause is a duty, not a bar. Library convention 15: a licence that asks for no reciprocity and no source code asks only that the notice travels with the copy, which is a duty on the acts it governs and not a bar on putting the copy under other terms. dalicc:ChangeLicense is therefore a permission here, and the prohibition the record carried before is removed. The text reads: "Permission to use, copy, modify, and/or distribute this software for any purpose with or without fee is hereby granted, provided that the above copyright notice and this permission notice appear in all copies." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.

      was permission dalicc:ChangeLicense with duties [dalicc:compliantLicense]

      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. Its duty dalicc:compliantLicense is marked as a library convention, family rule 15: Permissive records permit relicensing.

    • changed permission dalicc:chargeDistributionFee

      was permission dalicc:chargeDistributionFee

    • 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.

    • changed permission odrl:derive with duties [cc:Attribution, cc:Notice]

      was permission odrl:derive with duties [cc:Attribution, cc:Notice]

      Manual edit Removed the quoted evidence of duty cc:Attribution on odrl:derive, duty cc:Attribution on odrl:distribute, duty cc:Attribution on odrl:modify: the quoted sentence does not name the act. The statements stay, read from the text without a linked quote.

    • changed permission odrl:distribute with duties [cc:Attribution, cc:Notice]

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.
