License-wide duties

This license states no duties that apply to the work as a whole.

What applies by default

The statements above are the library's reading of this license: each is marked with the sentence it rests on, or as a library convention where the text is not explicit. The statements below are the ones the DALICC reasoner supplies for acts the license says nothing about, from the default rules of the dependency graph it reasons with. Each one names the legal source it rests on. None of it is in the record.

No default rule of that graph reaches this license: it speaks about every act the rules are about.

Models the shortest member of the BSD family, in which the no-endorsement clause is the only condition of the grant. Unlike every other BSD record in the library this one carries no attribution or notice duty at all, because the text imposes none. Nothing here is legal advice.

8 findings

  • major Rubric 3 odrl:permission applied

    The grant reads "Redistribution and use in source and binary forms, with or without modification, are permitted provided that neither the name of Emin Martinian nor the names of any contributors are be used to endorse or promote products derived from this software without specific prior written permission". Redistribution and use are permitted, so the record carries the usual BSD permission set.

  • major Rubric 4 odrl:prohibition applied

    The single condition is the no-endorsement clause quoted above, modelled as a dalicc:promote prohibition. dalicc:ChangeLicense is prohibited as in the rest of the family. (Corrected on 2026-09-15 by the verification of this review group: see the rubric 3 finding on relicensing below.)

  • major Rubric 5 odrl:duty applied

    No cc:Attribution and no cc:Notice duty is written. The text has no retention condition: it does not require the copyright notice, the list of conditions or the disclaimer to be reproduced. This is the one real difference from every other BSD record and it changes the compatibility answers, so it is recorded as a major finding.

  • minor Rubric 6 dalicc:additionalClauses applied

    The grant sentence is quoted verbatim because its structure, a permission whose only proviso is a prohibition, is unusual enough that a reader should be able to check it. The warranty and liability sentences are split as elsewhere in this review group.

  • info Rubric 7 cc:jurisdiction applied

    The text names no legal system and sets no term, so cc:jurisdiction is dalicc:worldwide and dalicc:validityType is dalicc:perpetual.

  • info Rubric 9 record none

    The consistency check of app.services.composer with the dependency graph dg_default returned an empty conflict list.

  • info Rubric 10 record none

    Follows licensedata/licenses/BSD-3-Clause.ttl for the prohibition set and BSD-2-Clause for the permission set, but carries none of the duties either of them carries.

  • major Rubric 3 odrl:permission applied

    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 earlier reading wrote is removed. The text reads: "Redistribution and use in source and binary forms, with or without modification, are permitted provided that neither the name of Emin Martinian nor the names of any contributors are be used to endorse or promote products derived from this software without specific prior written permission." The permission carries no duty, as on the public-domain dedications, because nothing has to travel with the copy.

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.

    The changes since version 1 recorded which sentence of the text each statement rests on and named the license the record itself is published under.

    3 changes

    • changed permission dalicc:ChangeLicense

      was permission dalicc:ChangeLicense

      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.

    • changed prohibition dalicc:promote

      was prohibition dalicc:promote

      Manual edit The statement now quotes the sentence of the licence text it rests on: "Redistribution and use in source and binary forms, with or without modification, are permitted provided that neither the name of Emin Martinian nor the names of any contributors are be used to endorse or promote products derived from this software without specific prior written permission."

    • 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

    Created from the license text on 2026-09-15 (BSD variants).

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.
