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.

Alternative condition set
Clauses 2 and 3 each let the licensee satisfy any one of four listed alternatives.

Findings
13 recorded, 9 applied to the record, 0 proposed

Models the licence of the Ruby language, an Artistic-shaped text in which the conditions on modification and on binary distribution are each a choice of four alternatives. Because a licensee need satisfy only one of them, none of the four becomes a duty; the choice is recorded in dalicc:alternativeConditionSet and both clauses are quoted in full.

13 findings

  • info Rubric 1 spdx:licenseId applied

    File name, record identifier, SPDX identifier and IRI local name are all Ruby.

  • info Rubric 2 odrl:target applied

    One odrl:AssetCollection of dct:type dcmitype:Software. The text speaks of source form, object code, binaries and library files.

  • major Rubric 3 odrl:permission applied

    Clause 1 reads "You may make and give away verbatim copies of the source form of the software without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers", clause 2 permits modification and clause 4 says "You may modify and include the part of the software into any other software (possibly commercial)". The record permits reproduce, distribute, modify, derive, display, present, commercial use, derivative works, modified works and the distribution fee.

  • major Rubric 3 odrl:permission applied

    dalicc:ChangeLicense is permitted with the dalicc:compliantLicense duty. Clause 4 lets the software be included in any other software, and no sentence bars putting a copy under other terms; the notice condition of clause 1 has to survive.

  • major Rubric 4 odrl:prohibition applied

    dalicc:exemptedMaterial is prohibited for clause 4, "But some files in the distribution are not written by the author, so that they are not under these terms. For the list of those files and their copying conditions, see the file LEGAL." That is material carved out of the grant, which is what the term means where it is used as a prohibition.

  • minor Rubric 4 odrl:prohibition none

    dalicc:promote is not prohibited. The text has no endorsement or trademark clause; the non-standard-names alternatives of clauses 2 and 3 are about telling versions apart, not about claiming a connection with the author.

  • major Rubric 5 odrl:duty applied

    cc:Attribution and cc:Notice hang off odrl:distribute, odrl:modify and odrl:derive, and they are the only unconditional duties in the text: clause 1 requires that you "duplicate all of the original copyright notices and associated disclaimers".

  • major Rubric 5 odrl:duty applied

    No cc:SourceCode, no dalicc:rename and no dalicc:originalVersionOffer, although clauses 2 and 3 name each of those acts. Each is one of four alternatives introduced by "provided that you do at least ONE of the following", and a duty would say that the licensee has to do it. The existing Artistic-1.0 record reads the corresponding clauses the other way and turns two of the alternatives into duties; that divergence is reported and not edited.

  • major Rubric 6 dalicc:LiabilityLimitation applied

    No dalicc:LiabilityLimitation. Clause 6 is a warranty disclaimer and the text has no limitation of liability at all, which is unusual for this family and is stated here so that a reader does not take the absence for an oversight. The clause number is dropped from the quoted literal.

  • 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:alternativeConditionSet none

    The one-of-four structure cannot be said in the deontic model. dalicc:alternativeConditionSet carries it as a short literal, in the wording the three Artistic records use, and clauses 2 and 3 are quoted in full.

  • 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

    The nearest sibling is licensedata/licenses/Artistic-1.0.ttl, from which this text descends. The differences are: no clause asking for a prominent notice in each changed file, so no dalicc:modificationNotice; no endorsement clause, so no dalicc:promote prohibition; no fee clause, so no dalicc:chargeLicenseFee statement; relicensing permitted rather than prohibited; and the alternatives left as alternatives.

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.

    • 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.

    • 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 (Permissive variants).
