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. Not a ban on suing: a patent claim over the work ends the patent license, or the whole license, as the text provides.
Sublicense survival
Yes
Terminates on breach
Yes

Clauses

Warranty disclaimer

Covered Software is provided under this License on an “as is” basis, without warranty of any kind, either expressed, implied, or statutory, including, without limitation, warranties that the Covered Software is free of defects, merchantable, fit for a particular purpose or non-infringing. The entire risk as to the quality and performance of the Covered Software is with You. Should any Covered Software prove defective in any respect, You (not any Contributor) assume the cost of any necessary servicing, repair, or correction. This disclaimer of warranty constitutes an essential part of this License. No use of any Covered Software is authorized under this License except under this disclaimer.

Limitation of liability

Under no circumstances and under no legal theory, whether tort (including negligence), contract, or otherwise, shall any Contributor, or anyone who distributes Covered Software as permitted above, be liable to You for any direct, indirect, special, incidental, or consequential damages of any character including, without limitation, damages for lost profits, loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses, even if such party shall have been informed of the possibility of such damages. This limitation of liability shall not apply to liability for death or personal injury resulting from such party’s negligence to the extent applicable law prohibits such limitation. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so this exclusion and limitation may not apply to You.

Additional clauses

1.5. "Incompatible With Secondary Licenses" means (a) that the initial Contributor has attached the notice described in Exhibit B to the Covered Software; or (b) that the Covered Software was made available under the terms of version 1.1 or earlier of the License, but not also under the terms of a Secondary License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this version of the License, the notice described in Exhibit B of this License must be attached. Exhibit B - "Incompatible With Secondary Licenses" Notice --------------------------------------------------------- This Source Code Form is "Incompatible With Secondary Licenses", as defined by the Mozilla Public License, v. 2.0.

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

Models code released under the Mozilla Public License 2.0 that carries the Exhibit B notice, so that the option of also distributing it under a Secondary License (GPL, LGPL or AGPL) is switched off. The licence text is the same as MPL-2.0, so the record mirrors MozillaPublicLicenseVersion20 and records the difference as quoted clause text. Nothing here is legal advice.

8 findings
  • major Rubric 3 odrl:permission applied

    Section 2.1 grants rights "under intellectual property rights (other than patent or trademark) ... to use, reproduce, make available, modify, display, perform, distribute, and otherwise exploit its Contributions" and, in 2.1(b), "under Patent Claims of such Contributor to make, use, sell, offer for sale, have made, import, and otherwise transfer". dalicc:patentGrant is therefore a permission, and section 3.2(b), which lets the licensee "sublicense it under different terms", supports dalicc:sublicense. The existing MozillaPublicLicenseVersion20 record carries neither statement; it was not edited.

  • major Rubric 4 odrl:prohibition applied

    The grant excludes trademark rights, so dalicc:promote is a prohibition. Section 5.2 terminates the grant where the licensee asserts a patent claim, modelled as a dalicc:patentRetaliationTermination prohibition and quoted in full. dalicc:ChangeLicense is prohibited, as on the MPL-2.0 record.

  • major Rubric 5 odrl:duty applied

    cc:ShareAlike hangs off the odrl:Set, not off the individual acts. This mirrors the existing MozillaPublicLicenseVersion20 record exactly, because the two records model the same text and must give the same compatibility answers. Note that the CDDL and MPL 1.x records in this review group attach the same file-level reciprocity to odrl:distribute, odrl:modify and odrl:derive instead, following their own parent record; the library therefore carries two shapes for one concept, which is reported for the consolidation.

  • major Rubric 6 dalicc:additionalClauses applied

    The whole point of the identifier is quoted: the definition of "Incompatible With Secondary Licenses" in section 1.5, the Larger Work clause in section 3.3 whose Secondary License option this variant withholds, section 10.4 and the Exhibit B notice itself, plus the patent retaliation clause. The warranty and liability sections are those of MPL-2.0 and are quoted word for word.

  • minor Rubric 7 cc:jurisdiction applied

    The grant itself is world-wide ("a world-wide, royalty-free, non-exclusive license"), so cc:jurisdiction stays dalicc:worldwide and the applicable-law and venue clause is quoted in dalicc:additionalClauses instead of being turned into a bpicounty IRI. A choice of law is not a jurisdiction port and the library reserves cc:jurisdiction with a country for ports.

  • gap Rubric 8 dalicc:additionalClauses none

    Two clauses have no vocabulary term. Automatic termination on breach with a cure period is a policy quality with no property to hang it on; proposed term dalicc:terminatesOnBreach as a property over the existing dalicc:terminationOnBreach concept. The survival of validly granted end user licences after termination has no term either; proposed term dalicc:sublicenseSurvival. Both clauses are quoted in dalicc:additionalClauses.

  • info Rubric 9 record none

    The consistency check of app.services.composer with the dependency graph dg_default returned an empty conflict list. cc:ShareAlike is required and dalicc:ChangeLicense is prohibited, which is the combination the check expects; asserting both cc:ShareAlike and a dalicc:ChangeLicense permission would have been reported as a direct conflict.

  • major Rubric 10 record applied

    The licence text of MPL-2.0-no-copyleft-exception is byte for byte the Mozilla Public License 2.0; the identifier marks covered software whose Exhibit B notice is present. A separate record is justified because the compatibility answer differs (this code may not be combined into a GPL work under the Secondary License option), but the two records must stay aligned. Differences from MozillaPublicLicenseVersion20 today: this record adds dalicc:patentGrant, dalicc:sublicense, dalicc:patentRetaliationTermination, cc:DerivativeWorks and dalicc:chargeDistributionFee. The first three follow the review decisions; the last two follow the library convention carried by more than 320 records. The existing record was not edited.

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.

  1. Version 2 current2026-09-24 Giray Havur

    Named the licence the record itself is published under, CC BY 4.0, by its canonical address beside cc:license.

    1 change
    • added dct:license <https://creativecommons.org/licenses/by/4.0/>

      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.

  2. Version 1

    Created from the license text on 2026-09-15 (Mozilla and CDDL).

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.
