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.

Clauses

Additional clauses

Verdict

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

The record models the 1.1 license as a BSD-style permissive license with an acknowledgement clause and two name restrictions. dalicc:PromotionSpecification holds the acknowledgement of clause 3, dalicc:additionalClauses the naming restriction of clause 5, and dalicc:promote is prohibited for clause 4. The notice duty was attached to distribution only, although clauses 1 and 2 apply to every redistribution "with or without modification".

6 findings

  • major Rubric 5 odrl:duty applied

    Clause 1 reads: "Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer", and the whole condition block is introduced by "Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met". The cc:Notice duty was on odrl:distribute only. Added it to odrl:modify and odrl:derive.

  • info Rubric 4 odrl:prohibition none

    dalicc:promote is prohibited and clause 4 supports it: "The names \"Apache\" and \"Apache Software Foundation\" must not be used to endorse or promote products derived from this software without prior written permission."

  • info Rubric 5 odrl:duty proposed

    dalicc:rename on odrl:modify is supported by clause 5: "Products derived from this software may not be called \"Apache\" nor may \"Apache\" appear in their name". It is not attached to odrl:derive, where the same clause applies.

  • info Rubric 8 vocabulary none

    Version 1.1 grants no patent rights and has no patent retaliation clause. That is the substantive difference from version 2.0 and it is invisible in the model, because neither record can express a patent grant. See the Apache-2.0 record.

  • minor Rubric 2 odrl:target proposed

    The asset collection lists dalicc:CreativeWork and dcmitype:Dataset next to dcmitype:Software. The 1.1 text speaks only of software and its documentation.

  • 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: cc:attributionName and dct:publisher both began with a space.

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.

  1. Version 2 current2026-09-24 Giray Havur

    The content review of 2026-09-15 changed 2 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.

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.
