Prohibitions

This license states no prohibitions.

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.

  • 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. Not a ban on suing: a patent claim over the work ends the patent license, or the whole license, as the text provides.

Record changed since this review
yes (version 2, 2026-09-24)
Findings
9 recorded, 6 applied to the record, 0 proposed

The record models the Eclipse Public License 2.0 with attribution, notice and modification-notice duties and a permission to distribute under a different license with a compliance duty, which matches section 3.1(b). Four things the text states plainly were missing: commercial use, the source-code duty, sublicensing, and both liability clauses. All were added.

9 findings
  • minor Rubric 1 spdx:licenseId applied

    The record id is the SPDX list id but the field was absent.

  • major Rubric 3 odrl:permission applied

    Section 4 is headed COMMERCIAL DISTRIBUTION and opens "Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like", and the section 2 grant is royalty-free with no field-of-use limit. The record did not permit cc:CommercialUse, so the license read as non-commercial. Added.

  • major Rubric 5 odrl:duty applied

    Section 3.1(a) states: "the Program must also be made available as Source Code, in accordance with section 3.2, and the Contributor must accompany the Program with a statement that the Source Code for the Program is available under this Agreement". No cc:SourceCode duty was recorded. Added to distribute, modify and derive.

  • major Rubric 3 odrl:permission applied

    Section 2(a) grants the right to "reproduce, prepare Derivative Works of, publicly display, publicly perform, Distribute and sublicense the Contribution". Added odrl:grantUse.

  • minor Rubric 6 dalicc:WarrantyDisclaimer applied

    Sections 5 and 6 were not recorded. Added both, quoted.

  • gap Rubric 8 vocabulary none

    Section 2(b) grants a patent license and section 7 terminates it on patent litigation. Proposed: dalicc:patentGrant, dalicc:patentRetaliationTermination.

  • minor Rubric 4 odrl:prohibition none

    The record still has no prohibition. Section 3.3 forbids removing or altering any copyright, patent, trademark or attribution notice, which is closer to a notice duty than to a prohibition, so nothing was added.

  • info Rubric 6 dalicc:additionalClauses none

    The Secondary License mechanism, which is what makes this version GPL compatible, is quoted in dalicc:additionalClauses. It is prose only and therefore invisible to the compatibility checker.

  • major Rubric 10 record applied

    Standard-license addition of 2026-09-15, decision 9: the record was corrected against its new siblings and versioned. The review's finding on family consistency and consolidation decision 4: the record carried no prohibition although section 7 says 'If Recipient institutes patent litigation against any entity ... alleging that the Program itself ... infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate', it modelled no reciprocity although section 3.1 requires the Program in source form to be 'made available under this Agreement', its dalicc:additionalClauses began with the paraphrase 'Compliant License according to 1. DEFINITIONS:' instead of the quotation, and dct:publisher was 'N.N.'.

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 content review of 2026-09-15 added 2 clause texts, 1 identification detail and 2 permissions, changed 3 permissions, recorded the relation to the record this one was adapted from and recorded the review state. Later changes brought it in line with its family and its text in the verification of 2026-09-15, recorded which sentence of the text each statement rests on and named the license the record itself is published under.

  2. Version 1

    The version this model had before the content review of 2026-09-15.

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.
