Prohibitions

This license states no prohibitions.

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.

Promote by default rule (adopted)

This license says nothing about Promote, and the graph applies this reading in all jurisdictions it covers: it is not permitted unless the license permits it.

A licence that says nothing about endorsement is read as not allowing it: the licence gives the licensee no right to use the licensor's name or marks in a way that states or implies that the licensor endorses the licensee or its product, while stating truthfully that a work is based on or uses the licensed work is a different act that this rule does not decide. A copyright licence grants rights in the work, and the right to use a name or a trademark is a separate right under trademark law and the protection of names, which a silent copyright licence does not pass on. Combining a licence that is silent about endorsement with one that permits it shows a conflict marked as coming from this rule.

Basis Trademark and name rights are separate from copyright: Regulation (EU) 2017/1001 article 9 lets the proprietor of an EU trade mark prevent all third parties not having his consent from using the sign in the course of trade, and Directive (EU) 2015/2436 article 10, 15 U.S.C. 1114 and 1125(a), section 12 BGB and section 43 ABGB protect marks and names in the same way. The library's evidence is Creative Commons 4.0 section 2(b)(2): Patent and trademark rights are not licensed under this Public License. A copyright licence that is silent grants no right to use the licensor's name or marks to suggest endorsement (Worldwide)

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: 8 recorded, 6 applied to the record, 0 proposed

Models the one-clause BSD licence, which keeps only the source-form retention condition of the BSD family. The record follows BSD-2-Clause for everything the two share and drops nothing else. 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 the following conditions are met". The record therefore permits reproduce, distribute, modify, derive, display, present, commercial use, derivative works, modified works and the distribution fee, the same set the BSD-2-Clause record carries.
minor Rubric 4 odrl:prohibition applied

The licence has no endorsement clause, so no dalicc:promote statement is made at all: silence about trademarks is not a grant and not a refusal. This departs from the existing BSD-2-Clause record, which permits dalicc:promote although the two-clause text is equally silent. dalicc:ChangeLicense is prohibited, as in every other BSD record. (Corrected on 2026-09-15 by the verification pass: see the rubric 3 finding on relicensing below.)
major Rubric 5 odrl:duty applied

The retention conditions are the whole content of the licence. cc:Attribution and cc:Notice hang off odrl:distribute, odrl:modify and odrl:derive, because the text requires the copyright notice, the list of conditions and the disclaimer to travel with every redistributed and every modified copy.
minor Rubric 6 dalicc:WarrantyDisclaimer applied

The single disclaimer paragraph of the BSD family carries two distinct clauses. This record splits it at the sentence boundary: the warranty sentence goes to dalicc:WarrantyDisclaimer and the "IN NO EVENT SHALL" sentence to dalicc:LiabilityLimitation, both verbatim. The existing BSD-2-Clause, BSD-3-Clause and BSD-4-Clause records keep the whole paragraph in dalicc:WarrantyDisclaimer and carry no dalicc:LiabilityLimitation; those records were not edited, and the divergence is reported for the consolidation.
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-2-Clause.ttl. The only modelled difference is that the one-clause text has no binary-form retention condition; since the library expresses both conditions with the same cc:Attribution and cc:Notice duties, the two records carry the same duty set, and the difference is visible only in the quoted clause text.
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 the following conditions are met: 1. Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.
