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.

Further terms

These are the things the license says about itself beyond the acts it permits, forbids and requires: when it ends, how long there is to put a breach right, which law governs it, and so on. A term that comes from the DALICC vocabulary links to its definition.

Or later version option: Yes

Review

Written from the license text by: Giray Havur
Written on: 2026-09-15
Second review: not yet done
Record changed since this review: yes (version 2, 2026-09-24)
Findings: 10 recorded, 6 applied to the record, 1 proposed

The record models version 2.8 of the OpenLDAP Public License, a BSD-form license whose third condition asks for a verbatim copy of the license document in every redistribution. It adds a revision clause that lets a licensee use the software under any later revision of the license, and a sentence keeping title to copyright with the copyright holders; both are quoted.

10 findings

major Rubric 3 odrl:permission applied

"Redistribution and use of this software and associated documentation ("Software"), with or without modification, are permitted provided that the following conditions are met". The permissive core, as on BSD-3-Clause.
major Rubric 5 odrl:duty applied

The three conditions are the retention of copyright statements and notices in source form, their reproduction with the list of conditions and the disclaimer in binary form, and a verbatim copy of the license document in every redistribution. cc:Attribution and cc:Notice on distribute, modify and derive.
major Rubric 4 odrl:prohibition applied

The text reads: "The names of the authors and copyright holders must not be used in advertising or otherwise to promote the sale, use or other dealing in this Software without specific, written prior permission." That is dalicc:promote as a prohibition. dalicc:ChangeLicense is prohibited because the text requires the license itself to travel with every copy, which is the reading IscLicense and BSD-3-Clause take of the same clause. The MIT record does not carry the prohibition although its text has the same requirement, so the library is not uniform here. (Corrected on 2026-09-15 by the verification pass: see the rubric 3 finding on relicensing below.)
gap Rubric 8 dalicc:orLaterVersionOption proposed

The revision clause reads: "You may use this Software under terms of this license revision or under the terms of any subsequent revision of the license." That is an or-later option outside the GNU family. dalicc:orLaterVersionOption would express it as true, but the property is so far used only on the GNU records and the consolidation decision that introduced it named those four records only, so the triple is proposed and not written, and the clause is quoted in dalicc:additionalClauses instead.
minor Rubric 6 dalicc:additionalClauses applied

Three sentences are quoted: the revision clause, the advertising and title sentence, and the registered-trademark sentence. The last one is a statement of fact rather than a term, but it is the reason the promote prohibition matters here.
info Rubric 7 cc:jurisdiction none

The text names no legal system and no term, so cc:jurisdiction is dalicc:worldwide and dalicc:validityType is dalicc:perpetual.
info Rubric 2 odrl:target applied

One odrl:AssetCollection of dct:type dcmitype:Software, following BSD-3-Clause. The text licenses software and associated documentation.
info Rubric 9 record none

The consistency check with the axioms of dg_default returned no conflicts.
info Rubric 10 record none

The library holds no other OpenLDAP record, so no dalicc:variantKind is written even though the text calls itself version 2.8. Against BSD-3-Clause the differences are the verbatim-copy condition, the revision clause and the title sentence.
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 of this software and associated documentation ("Software"), with or without modification, are permitted provided that the following conditions are met: 1. Redistributions in source form must retain copyright statements and notices ..." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.

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.

Version 2 current2026-09-24 Giray Havur

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.

  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.

  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.

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.
