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.
Clauses
Warranty disclaimer
THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT.
Limitation of liability
IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM OTHER DEALINGS IN THE FONT SOFTWARE.
Additional clauses
Neither the Font Software nor any of its individual components, in Original or Modified Versions, may be sold by itself. Original or Modified Versions of the Font Software may be bundled, redistributed and/or sold with any software, provided that each copy contains the above copyright notice and this license. These can be included either as stand-alone text files, human-readable headers or in the appropriate machine-readable metadata fields within text or binary files as long as those fields can be easily viewed by the user. No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users. The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission. The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license. The requirement for fonts to remain under this license does not apply to any document created using the Font Software. This license becomes null and void if any of the above conditions are not met.

The SIL Open Font License is the standard licence for open fonts: use, study, copy, merge, embed, modify, redistribute and sell, on condition that the font is never sold on its own, that the notice and the licence travel with every copy, that a modified version does not use a reserved font name and that the font software stays under this licence. Nothing here is legal advice.

info Rubric 2
odrl:targetappliedA font is a computer program and a work of design at once, so the record carries dalicc:CreativeWork and dcmitype:Software, the pair the review group uses for all four font records. The licence itself speaks of "Font Software" and defines it as "the set of files released by the Copyright Holder(s) under this license", which may include "source files, build scripts and documentation".
-
major Rubric 3
odrl:permissionappliedThe grant reads: "Permission is hereby granted, free of charge, to any person obtaining a copy of the Font Software, to use, study, copy, merge, embed, modify, redistribute, and sell modified and unmodified copies of the Font Software, subject to the following conditions." That is the permissive base set, including cc:CommercialUse and dalicc:chargeDistributionFee. The licence says nothing about patents or sublicensing, so neither is written.
-
major Rubric 4
odrl:prohibitionappliedThree. dalicc:sellCopy, because condition 1 says "Neither the Font Software nor any of its individual components, in Original or Modified Versions, may be sold by itself"; this is a restriction on how a copy may be sold, not a ban on commercial use, which condition 2 expressly allows when the font is bundled with software. dalicc:promote, from condition 4, which bars the use of the names of the Copyright Holders or Authors to promote, endorse or advertise a Modified Version. dalicc:ChangeLicense, from condition 5: the Font Software "must not be distributed under any other license".
-
major Rubric 5
odrl:dutyappliedCondition 5 requires the Font Software, modified or unmodified, to be "distributed entirely under this license", which is cc:ShareAlike. Condition 2 requires each copy to contain "the above copyright notice and this license", which is cc:Attribution and cc:Notice. The duties hang on odrl:distribute, odrl:modify and odrl:derive rather than on the licence, because the last sentence of condition 5 takes documents made with the font out of the reciprocity: "The requirement for fonts to remain under this license does not apply to any document created using the Font Software."
-
major Rubric 5
dalicc:renameappliedCondition 3 says "No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder", which is dalicc:rename on odrl:modify and odrl:derive. It binds only where the copyright statement of the font actually declares a reserved font name; this record, the plain OFL-1.1 id, carries the duty because the clause is part of the licence.
-
minor Rubric 6
dalicc:additionalClausesappliedThe disclaimer is split at "IN NO EVENT SHALL" into dalicc:WarrantyDisclaimer and dalicc:LiabilityLimitation. dalicc:additionalClauses carries all five conditions and the termination sentence, so that a reader can see the wording the duties were read from.
-
info Rubric 7
cc:jurisdictionappliedThe licence names no governing law and no term, so cc:jurisdiction is dalicc:worldwide and dalicc:validityType is dalicc:perpetual.
-
gap Rubric 8
dalicc:additionalClausesnoneTwo gaps. The termination sentence, "This license becomes null and void if any of the above conditions are not met", has no property; proposed dalicc:terminatesOnBreach. The reserved font name is a named string that the copyright statement declares, and dalicc:rename cannot carry which name is reserved; proposed dalicc:reservedName as a literal qualifier on the rename duty.
-
info Rubric 9
recordnoneThe consistency check of app.services.composer with the axioms of dg_default returned an empty list for this record.
-
info Rubric 10
familynoneOFL-1.1, OFL-1.1-RFN and OFL-1.1-no-RFN have one and the same licence text: the three SPDX plain text files are byte for byte identical. The ids exist to record whether the copyright statement of a particular font declares a Reserved Font Name. The three records therefore differ in exactly one triple, the dalicc:rename duty on odrl:modify and odrl:derive.
Report an issue The review record as JSON The review checks the model against the license text. It is not legal advice.
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, named the license the record itself is published under and removed the quotes that do not name the act they support.

Version 1
Created from the license text on 2026-09-15 (Fonts and documentation).
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.
