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.

Findings
15 recorded, 12 applied to the record, 0 proposed

Models the first Apache licence, the six-clause BSD-style text the Apache Group used before version 1.1. It keeps the two retention clauses of BSD, adds the advertising acknowledgement, the endorsement bar and the bar on calling a derived product Apache, and adds a sixth clause that puts the acknowledgement on every redistribution of any form. The record follows Apache-1.1 for its clause texts and for dalicc:PromotionSpecification.

15 findings

  • info Rubric 1 spdx:licenseId applied

    File name, record identifier, SPDX identifier and IRI local name are all Apache-1.0.

  • info Rubric 2 odrl:target applied

    One odrl:AssetCollection of dct:type dcmitype:Software. The text licenses source and binary forms of a program.

  • major Rubric 3 odrl:permission applied

    The grant reads "Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met". The record therefore permits reproduce, distribute, modify, derive, display, present, commercial use, derivative works, modified works and the distribution fee, the set Apache-1.1 carries.

  • major Rubric 3 odrl:permission applied

    dalicc:ChangeLicense is permitted and carries the dalicc:compliantLicense duty. The text keeps conditions that have to survive a relicensing, and it nowhere bars putting a copy under other terms, which is family rule 15.

  • major Rubric 4 odrl:prohibition applied

    Clause 4 reads "The names "Apache" and "Apache Software Foundation" must not be used to endorse or promote products derived from this software without prior written permission", so dalicc:promote is prohibited.

  • major Rubric 5 odrl:duty applied

    cc:Attribution and cc:Notice hang off odrl:distribute, odrl:modify and odrl:derive, because clauses 1 and 2 make the copyright notice, the list of conditions and the disclaimer travel with every source and every binary copy. dalicc:advertisingAcknowledgement carries clause 3 and dalicc:addStatement carries clause 6; both hang off odrl:distribute, since each is triggered by handing the work on rather than by changing it.

  • minor Rubric 5 odrl:duty applied

    dalicc:rename hangs off odrl:modify and odrl:derive for clause 5, "Products derived from this software may not be called "Apache" nor may "Apache" appear in their name". Apache-1.1 attaches the same duty for the same clause.

  • minor Rubric 5 odrl:duty applied

    No dalicc:modificationNotice. The text asks nowhere for a record of the changes made, and the consolidation decision of 2026-09-15 is that a permissive record gets that duty only where its text asks for one. The Apache-1.1 record carries the duty although its text is silent in the same way; the divergence is reported rather than edited.

  • minor Rubric 6 dalicc:WarrantyDisclaimer applied

    The single disclaimer paragraph carries two clauses. The record splits it at the sentence boundary: the warranty sentence goes to dalicc:WarrantyDisclaimer and the liability sentence to dalicc:LiabilityLimitation, both verbatim. This follows BSD-1-Clause, which split the same paragraph on 2026-09-15.

  • info Rubric 6 dalicc:PromotionSpecification applied

    dalicc:PromotionSpecification carries the acknowledgement wording itself, following Apache-1.1, and clauses 3 and 6 are quoted in full in dalicc:additionalClauses so that a reader sees where the wording has to appear.

  • minor Rubric 6 dalicc:WarrantyDisclaimer applied

    The disclaimer uses the typewriter quotation marks of the original (``AS IS''), which are kept verbatim.

  • info Rubric 7 cc:jurisdiction applied

    The text names no legal system and sets no term, so cc:jurisdiction is dalicc:worldwide and dalicc:validityType is dalicc:perpetual.

  • info Rubric 8 dalicc:additionalClauses none

    Every clause of the text is either modelled or quoted. No clause needed a term the vocabulary does not have.

  • info Rubric 9 record none

    The consistency check of app.services.composer against the dependency graph dg_default returned an empty conflict list.

  • info Rubric 10 record none

    Read against licensedata/licenses/Apache-1.1.ttl, the differences are: the sixth clause, carried by the dalicc:addStatement duty; an explicit dalicc:advertisingAcknowledgement duty, which the Apache-1.1 record does not carry although its clause 3 is the same; no dalicc:modificationNotice duty; a warranty and a liability clause, which the Apache-1.1 record leaves out; and odrl:target dcmitype:Software alone.

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.

    4 changes

    • changed permission dalicc:ChangeLicense with duties [dalicc:compliantLicense]

      was permission dalicc:ChangeLicense with duties [dalicc:compliantLicense]

      Manual edit The statement is marked as a library convention, family rule 15: Permissive records permit relicensing: the text does not state it in as many words. Its duty dalicc:compliantLicense is marked as a library convention, family rule 15: Permissive records permit relicensing.

    • changed permission odrl:derive with duties [cc:Attribution, cc:Notice, dalicc:rename]

      was permission odrl:derive with duties [cc:Attribution, cc:Notice, dalicc:rename]

      Manual edit The statement now quotes the sentence of the licence text it rests on: "Products derived from this software may not be called "Apache" nor may "Apache" appear in their name, without prior written permission of the Apache Group."

    • changed prohibition dalicc:promote

      was prohibition dalicc:promote

      Manual edit The statement now quotes the sentence of the licence text it rests on: "The names "Apache" and "Apache Software Foundation" must not be used to endorse or promote products derived from this software without prior written permission."

    • 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.

    Created from the license text on 2026-09-22 (Permissive variants).

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.
