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.

Review

Written from the license text by: Giray Havur
Written on: 2026-09-22
Second review: not yet done
Record changed since this review: yes (version 2, 2026-09-24)
Findings: 13 recorded, 10 applied to the record, 0 proposed

Models the Carnegie Mellon variant of the MIT licence, the permission-to-use form that asks for the copyright notice in all copies, for the copyright and permission notices in the supporting documentation, and for the copyright holder's name to stay out of advertising. The grant does not name sublicensing, so the record makes no sublicensing statement.

13 findings

info Rubric 1 spdx:licenseId applied

File name, record identifier, SPDX identifier and IRI local name are all MIT-CMU. The SPDX full name is CMU License, which is the dct:title.
info Rubric 2 odrl:target applied

One odrl:AssetCollection of dct:type dcmitype:Software. The text covers the software and its associated documentation.
major Rubric 3 odrl:permission applied

The grant reads "Permission to use, copy, modify, and distribute this software and its associated documentation for any purpose and without fee is hereby granted". The record permits reproduce, distribute, modify, derive, display, present, commercial use, derivative works, modified works and the distribution fee. "for any purpose and without fee" carries cc:CommercialUse.
minor Rubric 3 odrl:permission applied

No dalicc:sublicense and no odrl:grantUse. Unlike the MIT text, this grant names neither sublicensing nor a right for the recipient of a copy to do the same, so no statement is made either way.
major Rubric 3 odrl:permission applied

dalicc:ChangeLicense is permitted with the dalicc:compliantLicense duty: the notice conditions are duties on the acts they govern, not a bar on relicensing.
major Rubric 4 odrl:prohibition applied

dalicc:promote is prohibited for "and that the name of the copyright holder not be used in advertising or publicity pertaining to distribution of the software without specific, written prior permission".
major Rubric 5 odrl:duty applied

cc:Attribution and cc:Notice hang off odrl:distribute, odrl:modify and odrl:derive for "provided that the above copyright notice appears in all copies, and that both that copyright notice and this permission notice appear in supporting documentation".
minor Rubric 6 dalicc:WarrantyDisclaimer applied

The single disclaimer paragraph carries two clauses. The record splits it at the sentence boundary: the warranty sentence goes to dalicc:WarrantyDisclaimer and the liability sentence to dalicc:LiabilityLimitation, both verbatim. This follows BSD-1-Clause, which split the same paragraph on 2026-09-15.
info Rubric 6 dalicc:additionalClauses applied

The opening sentence, under which a person agrees to the terms by obtaining, using or copying the software, is quoted. dalicc:recipientAssent is not used: that duty is about obtaining the assent of a recipient, while this sentence binds the licensee by conduct.
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 8 dalicc:additionalClauses none

No clause of this text needs a term the vocabulary does not have.
info Rubric 9 record none

The consistency check of app.services.composer against the dependency graph dg_default returned an empty conflict list.
info Rubric 10 record none

Read against licensedata/licenses/MIT.ttl the differences are three: the notice has to appear in the supporting documentation as well as in the copies, the advertising clause makes dalicc:promote a prohibition, and there is no sublicensing statement.

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.

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.
