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) Using the name or trademarks of the licensor or of contributors to endorse or promote a product.

    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)

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: "Do not make any legal claim against anyone accusing this software, with or without changes, alone or with other software, of infringing any patent claim." Not a ban on suing: a patent claim over the work ends the patent license, or the whole license, as the text provides.

The record models the Parity Public License 6.0.0, a strong copyleft licence written in plain language. You may do everything the contributor's copyright and patents would otherwise forbid, on condition that you contribute back: publish the source of your changes, of anything you combine the software with, and of anything you develop, deploy, monitor or run with it. That reach is wider than the work itself, which is why cc:ShareAlike and cc:SourceCode are licence-wide duties here.

11 findings

  • info Rubric 1 spdx:licenseId applied

    File name, record identifier, SPDX identifier and IRI local name agree. cc:legalcode points at the publisher's page for version 6.0.0 and dct:source at the SPDX entry. dct:publisher is left out: the Contributor and Source Code lines at the head of the text are per-project fill-ins, not a steward.

  • info Rubric 2 odrl:target applied

    dcmitype:Software only. The text speaks of software and source code throughout.

  • major Rubric 3 odrl:permission applied

    'If you follow the rules below, you may do everything with this software that would otherwise infringe either the contributor's copyright in it, any patent claim the contributor can license, or both.' Everything gives reproduce, distribute, modify, derive, display, present, cc:DerivativeWorks, dalicc:ModifiedWorks and cc:CommercialUse, and the patent half gives dalicc:patentGrant.

  • major Rubric 4 odrl:prohibition applied

    dalicc:ChangeLicense, because rule 4 makes the licence travel with every copy in any form and nothing in the text lets a licensee put this software under other terms. dalicc:patentRetaliationTermination for rule 5, 'Do not make any legal claim against anyone accusing this software, with or without changes, alone or with other software, of infringing any patent claim.' dalicc:promote is absent because the text has no trademark or endorsement clause at all.

  • major Rubric 5 odrl:duty applied

    cc:ShareAlike and cc:SourceCode are licence-wide, because rules 1 to 3 reach past distribution: 'Contribute software you develop, deploy, monitor, or run with this software', and contributing means 'publish all its source code, in the preferred form for making changes, through a freely accessible distribution system widely used for similar source code'. cc:Notice and cc:Attribution hang on odrl:distribute, odrl:modify and odrl:derive for rule 4, which asks for the text of the licence and for the contributor and source code lines.

  • major Rubric 6 dalicc:WarrantyDisclaimer applied

    The last paragraph disclaims warranty and liability in one sentence, so the whole sentence goes into dalicc:WarrantyDisclaimer and dalicc:LiabilityLimitation is left out, as in CAL-1.0. Four further clauses are quoted in dalicc:additionalClauses.

  • minor Rubric 6 dalicc:WarrantyDisclaimer applied

    The published text wraps that sentence in a pair of double asterisks, which is the markup the document uses for bold. The asterisks are dropped from the quoted literal; nothing else in the sentence is changed.

  • major Rubric 7 dalicc:terminatesOnBreach applied

    dalicc:terminatesOnBreach is true and dalicc:curePeriod is '30 days': the rules are conditions of the licence, and 'You are excused for unknowingly breaking 1, 2, or 3 if you contribute as required, or stop doing anything requiring this license, within 30 days of learning you broke the rule.' cc:jurisdiction is dalicc:worldwide; the text names no jurisdiction and no governing law.

  • gap Rubric 8 dalicc:compatibleLicenseTest none

    The licence states a test for the licence of the software you contribute, 'terms as permissive as this license', which dalicc:compatibleLicenseTest carries. The annotation normally sits beside a dalicc:ChangeLicense permission, and here dalicc:ChangeLicense is prohibited, because the test governs the other software you must publish and not this software. Proposed term: dalicc:outboundLicenseTest, so that a record can say which licence the material a copyleft duty reaches may carry, separately from whether this work may be relicensed.

  • info Rubric 9 record none

    The consistency check of app.services.composer, run against licensedata/dependencygraph/dg_default.ttl, returned no conflicts. A licence-wide cc:ShareAlike duty beside a prohibited dalicc:ChangeLicense is the whole-work copyleft shape the check expects.

  • major Rubric 10 record none

    Its nearest sibling is CAL-1.0, which also carries a licence-wide cc:ShareAlike duty and a source-code condition reaching past distribution. The difference is that CAL-1.0 permits dalicc:ChangeLicense with a dalicc:compliantLicense duty and this record prohibits it, and that Parity states its reciprocity as five rules rather than as conditions on named acts.

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

    The changes since version 1 recorded which sentence of the text each statement rests on and named the license the record itself is published under.

    2 changes

    • changed prohibition dalicc:patentRetaliationTermination

      was prohibition dalicc:patentRetaliationTermination

      Manual edit The statement now quotes the sentence of the licence text it rests on: "Do not make any legal claim against anyone accusing this software, with or without changes, alone or with other software, of infringing any patent claim."

    • 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 2026-09-22 (Source-available licences and riders).

    View JSON-LD Turtle RDF/XML

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.
