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.

Patent license ends if you sue
Yes. The text says: "automatically without notice from Apple if You, at any time during the term of this License, commence an action for patent infringement against Apple." Not a ban on suing: a patent claim over the work ends the patent license, or the whole license, as the text provides.
Cure period
30 days
Or later version option
Yes
Source publication period
for as long as the covered code is deployed or twelve (12) months from the date of initial deployment, whichever is longer
Terminates on breach
Yes

UNDER NO CIRCUMSTANCES SHALL APPLE BE LIABLE FOR ANY INCIDENTAL, SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE OR YOUR USE OR INABILITY TO USE THE ORIGINAL CODE, OR ANY PORTION THEREOF, WHETHER UNDER A THEORY OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE), PRODUCTS LIABILITY OR OTHERWISE, EVEN IF APPLE HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND NOTWITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE OF ANY REMEDY. In no event shall Apple's total liability to You for all damages under this License exceed the amount of fifty dollars ($50.00).

Accepting warranty or additional liability

6. Additional Terms. You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations and/or other rights consistent with the scope of the license granted herein ("Additional Terms") to one or more recipients of Covered Code. However, You may do so only on Your own behalf and as Your sole responsibility, and not on behalf of Apple. You must obtain the recipient's agreement that any such Additional Terms are offered by You alone, and You hereby agree to indemnify, defend and hold Apple harmless for any liability incurred by or claims asserted against Apple by reason of any such Additional Terms.

Additional clauses

1.4 "Deploy" means to use, sublicense or distribute Covered Code other than for Your internal research and development (R&D), and includes without limitation, any and all internal use or distribution of Covered Code within Your business or organization except for R&D use, as well as direct or indirect sublicensing or distribution of Covered Code by You to any third party in any form or manner. 2.2 You may Deploy Covered Code, provided that You must in each instance: (a) satisfy all the conditions of Section 2.1 with respect to the Source Code of the Covered Code; (b) make all Your Deployed Modifications publicly available in Source Code form via electronic distribution (e.g. download from a web site) under the terms of this License and subject to the license grants set forth in Section 3 below, and any additional terms You may choose to offer under Section 6. You must continue to make the Source Code of Your Deployed Modifications available for as long as you Deploy the Covered Code or twelve (12) months from the date of initial Deployment, whichever is longer; (c) if You Deploy Covered Code containing Modifications made by You, inform others of how to obtain those Modifications by filling out and submitting the information found at http://www.apple.com/publicsource/modifications.html, if available; and (d) if You Deploy Covered Code in object code, executable form only, include a prominent notice, in the code itself as well as in related documentation, stating that Source Code of the Covered Code is available under the terms of this License with information on how and where to obtain such Source Code. 3. Your Grants. In consideration of, and as a condition to, the licenses granted to You under this License: (a) You hereby grant to Apple and all third parties a non-exclusive, royalty-free license, under Your Applicable Patent Rights and other intellectual property rights owned or controlled by You, to use, reproduce, modify, distribute and Deploy Your Modifications of the same scope and extent as Apple's licenses under Sections 2.1 and 2.2; and (b) You hereby grant to Apple and its subsidiaries a non-exclusive, worldwide, royalty-free, perpetual and irrevocable license, under Your Applicable Patent Rights and other intellectual property rights owned or controlled by You, to use, reproduce, execute, compile, display, perform, modify or have modified (for Apple and/or its subsidiaries), sublicense and distribute Your Modifications, in any form, through multiple tiers of distribution. 4. Larger Works. You may create a Larger Work by combining Covered Code with other code not governed by the terms of this License and distribute the Larger Work as a single product. In each such instance, You must make sure the requirements of this License are fulfilled for the Covered Code or any portion thereof. 5. Limitations on Patent License. Except as expressly stated in Section 2, no other patent rights, express or implied, are granted by Apple herein. Modifications and/or Larger Works may require additional patent licenses from Apple which Apple may grant in its sole discretion. 7. Versions of the License. Apple may publish revised and/or new versions of this License from time to time. Each version will be given a distinguishing version number. Once Original Code has been published under a particular version of this License, You may continue to use it under the terms of that version. You may also choose to use such Original Code under the terms of any subsequent version of this License published by Apple. No one other than Apple has the right to modify the terms applicable to Covered Code created under this License. 9.1 Infringement. If any portion of, or functionality implemented by, the Original Code becomes the subject of a claim of infringement, Apple may, at its option: (a) attempt to procure the rights necessary for Apple and You to continue using the Affected Original Code; (b) modify the Affected Original Code so that it is no longer infringing; or (c) suspend Your rights to use, reproduce, modify, sublicense and distribute the Affected Original Code until a final determination of the claim is made by a court or governmental administrative agency of competent jurisdiction and Apple lifts the suspension as set forth below. Such suspension of rights will be effective immediately upon Apple's posting of a notice to such effect on the Apple web site that is used for implementation of this License. Upon such final determination being made, if Apple is legally able, without the payment of a fee or royalty, to resume use, reproduction, modification, sublicensing and distribution of the Affected Original Code, Apple will lift the suspension of rights to the Affected Original Code by posting a notice to such effect on the Apple web site that is used for implementation of this License. If Apple suspends Your rights to Affected Original Code, nothing in this License shall be construed to restrict You, at Your option and subject to applicable law, from replacing the Affected Original Code with non-infringing code or independently negotiating for necessary rights from such third party. 10. Trademarks. This License does not grant any rights to use the trademarks or trade names "Apple", "Apple Computer", "Mac OS X", "Mac OS X Server" or any other trademarks or trade names belonging to Apple (collectively "Apple Marks") and no Apple Marks may be used to endorse or promote products derived from the Original Code other than as permitted by and in strict compliance at all times with Apple's third party trademark usage guidelines which are posted at http://www.apple.com/legal/guidelinesfor3rdparties.html. 11. Ownership. Apple retains all rights, title and interest in and to the Original Code and any Modifications made by or on behalf of Apple ("Apple Modifications"), and such Apple Modifications will not be automatically subject to this License. Apple may, at its sole discretion, choose to license such Apple Modifications under this License, or on different terms from those contained in this License or may choose not to license them at all. Apple's development, use, reproduction, modification, sublicensing and distribution of Covered Code will not be subject to this License. 12.1 Termination. This License and the rights granted hereunder will terminate: (a) automatically without notice from Apple if You fail to comply with any term(s) of this License and fail to cure such breach within 30 days of becoming aware of such breach; (b) immediately in the event of the circumstances described in Section 13.5(b); or (c) automatically without notice from Apple if You, at any time during the term of this License, commence an action for patent infringement against Apple. 12.2 Effect of Termination. Upon termination, You agree to immediately stop any further use, reproduction, modification, sublicensing and distribution of the Covered Code and to destroy all copies of the Covered Code that are in your possession or control. All sublicenses to the Covered Code which have been properly granted prior to termination shall survive any termination of this License. Provisions which, by their nature, should remain in effect beyond the termination of this License shall survive, including but not limited to Sections 3, 5, 8, 9, 10, 11, 12.2 and 13. Neither party will be liable to the other for compensation, indemnity or damages of any sort solely as a result of terminating this License in accordance with its terms, and termination of this License will be without prejudice to any other right or remedy of either party. 13.1 Government End Users. The Covered Code is a "commercial item" as defined in FAR 2.101. Government software and technical data rights in the Covered Code include only those rights customarily provided to the public as defined in this License. This customary commercial license in technical data and software is provided in accordance with FAR 12.211 (Technical Data) and 12.212 (Computer Software) and, for Department of Defense purchases, DFAR 252.227-7015 (Technical Data -- Commercial Items) and 227.7202-3 (Rights in Commercial Computer Software or Computer Software Documentation). Accordingly, all U.S. Government End Users acquire Covered Code with only those rights set forth herein. 13.6 Dispute Resolution. Any litigation or other dispute resolution between You and Apple relating to this License shall take place in the Northern District of California, and You and Apple hereby consent to the personal jurisdiction of, and venue in, the state and federal courts within that District with respect to this License. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. 13.7 Entire Agreement; Governing Law. This License constitutes the entire agreement between the parties with respect to the subject matter hereof.

Findings
13 recorded, 7 applied to the record, 1 proposed

Version 1.1 of the Apple Public Source License. The deontic model is identical to the APSL-1.0 record; the text differs in that the notification of Deployed Modifications is owed to other users rather than to Apple, the export law clause is gone, and section 9.1 replaces the termination of the rights in Affected Original Code with a suspension that can be lifted. Those differences are in the quoted clauses, not in the permissions or duties.

13 findings
  • minor Rubric 1 spdx:licenseId applied

    The record carries the SPDX id APSL-1.1 as its file name, its IRI and its spdx:licenseId, the SPDX name as dct:title and the short forms people search for as dct:alternative. dalicc:variantKind is "version", because the library already holds APSL-2.0, of which this text is an earlier version.

  • info Rubric 2 odrl:target applied

    One odrl:AssetCollection of dct:type dcmitype:Software, the target the existing APSL-2.0 record carries. The licence speaks of Original Code, Modifications and Covered Code throughout and of nothing else, so no second asset type was added.

  • major Rubric 3 odrl:permission applied

    Section 2 grants, in its own words, a licence "to the extent of Apple's Applicable Patent Rights and copyrights covering the Original Code", and section 2.1 lets the licensee "use, copy, modify and distribute Original Code, with or without Modifications". The record therefore permits reproduce, distribute, modify, derive, display, present, commercial use, derivative works, modified works and the distribution fee, and adds dalicc:patentGrant for the patent limb of the same sentence. dalicc:sublicense is permitted because the definition of Deploy names sublicensing as one of the acts the licensee may perform under section 2.2.

  • major Rubric 4 odrl:prohibition applied

    Three prohibitions. dalicc:promote comes from section 10, which states that the licence grants no right to the Apple marks and that "no Apple Marks may be used to endorse or promote products derived from the Original Code". dalicc:ChangeLicense comes from section 2.1(b), "You may not offer or impose any terms on such Source Code that alter or restrict this License or the recipients' rights hereunder, except as permitted under Section 6". dalicc:patentRetaliationTermination comes from section 12.1(c), under which the licence terminates "automatically without notice from Apple if You, at any time during the term of this License, commence an action for patent infringement against Apple".

  • major Rubric 5 odrl:duty applied

    The duties hang off the acts the text names, not off the licence as a whole, because the reciprocity of the APSL is file level: section 2.2(b) reaches the Deployed Modifications, not the Larger Work, and section 4 expressly allows a Larger Work that combines Covered Code with code not governed by this licence. odrl:distribute carries cc:Attribution and cc:Notice (section 2.1(a) and (b)), cc:SourceCode and cc:ShareAlike (section 2.2(b), source of the Deployed Modifications "under the terms of this License"). odrl:modify and odrl:derive carry the same four plus dalicc:modificationNotice for the duty to document the modifications and to carry the Exhibit A notice. This is the shape the MPL-1.1, CDDL-1.1 and Nokia records of this review use.

  • minor Rubric 6 dalicc:WarrantyDisclaimer applied

    Section 8 is quoted verbatim in dalicc:WarrantyDisclaimer and the limitation of liability in dalicc:LiabilityLimitation. Section 6 goes into dalicc:WarrantyOrLiabilityAcceptance, because it lets a distributor offer and charge for warranty, support, indemnity or liability obligations of its own. dalicc:additionalClauses carries the definition of Deploy, the conditions of section 2.2, the grant back of section 3, the larger work clause, the patent limitation, the version clause, the trademark clause, the ownership clause, the termination clauses and the miscellaneous clauses.

  • minor Rubric 7 cc:jurisdiction applied

    cc:jurisdiction stays dalicc:worldwide: section 2 grants a "world-wide" licence and the choice of California law and of the Northern District of California in section 13 governs the contract, not the territory of the grant. Both sentences are quoted in dalicc:additionalClauses. dalicc:validityType is dalicc:perpetual, since the text sets no term.

  • gap Rubric 8 dalicc:additionalClauses none

    The external deployment trigger has no vocabulary term. Deploy is defined as "to use, sublicense or distribute Covered Code other than for Your internal research and development (R&D)" and it, rather than distribution, is what triggers the source publication duty of section 2.2(b). The clause is quoted; proposed term dalicc:networkUseTrigger, the same term another review group of this addition proposed for the RPL and CAL records.

  • gap Rubric 8 dalicc:additionalClauses none

    Automatic termination on breach with a thirty day cure period (section 12.1(a)) has no property a record can carry. Quoted in dalicc:additionalClauses; proposed term dalicc:terminatesOnBreach as a property over the existing dalicc:terminationOnBreach concept.

  • gap Rubric 8 dalicc:additionalClauses none

    Section 2.2(b) fixes how long the source of the Deployed Modifications must stay available ("for as long as you Deploy the Covered Code or twelve (12) months from the date of initial Deployment, whichever is longer"). No qualifier on a cc:SourceCode duty can carry that period; proposed term dalicc:sourcePublicationPeriod, as in another review group.

  • info Rubric 8 dalicc:orLaterVersionOption proposed

    Section 7 lets the licensee use the Original Code under the terms of any subsequent version of the licence Apple publishes, which is the shape dalicc:orLaterVersionOption expresses. The property is used only on the four GNU records today, so it was not written here; the clause is quoted instead. The triple would be dalicclib:APSL-1.1 dalicc:orLaterVersionOption true.

  • info Rubric 9 record none

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

  • info Rubric 10 record none

    Family: identical in every modelled statement to the APSL-1.0 record. The two differ only in the quoted clauses: version 1.1 drops the export law assurance, replaces the notification of Apple in section 2.2(c) with a duty to inform others, and rewrites section 9.1 as a suspension of the rights in the Affected Original Code rather than a termination of them. A separate record is justified by the separate SPDX id and by those clause texts, not by a different compatibility answer.

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.

  2. Version 1

    Created from the license text on 2026-09-15 (Apple Public Source License).

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.
