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.
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.
- Field of use restriction
- non-production use, unless the Licensor makes an Additional Use Grant permitting limited production use
- Terminates on breach
- Yes

The record models the Business Source License 1.1 as the template it is. The licence grants copying, modification, derivative works and redistribution but only 'non-production use', and each licensor fills in a Change Date, a Change License and an Additional Use Grant of its own. This is not an open source licence while the grant is in force: production use needs either an Additional Use Grant or a commercial licence bought from the licensor.

odrl:targetapplieddcmitype:Software only, following CAL-1.0 and the other software records: the text speaks of the Licensed Work as software distributed in versions.

major Rubric 3
odrl:permissionappliedThe grant is one sentence: 'The Licensor hereby grants you the right to copy, modify, create derivative works, redistribute, and make non-production use of the Licensed Work.' That gives odrl:reproduce, odrl:modify, odrl:derive, cc:DerivativeWorks, odrl:distribute and dalicc:ModifiedWorks. No display or performance permission: the text does not mention either. No dalicc:patentGrant: the text grants no patent licence.
-
minor Rubric 3
cc:CommercialUseappliedcc:CommercialUse is left unstated. The licence draws its line between production and non-production use, not between commercial and non-commercial use, so a commercial licensee may still use the work outside production. The line is carried by dalicc:fieldOfUseRestriction and by the quoted clause 'you must purchase a commercial license from the Licensor, its affiliated entities, or authorized resellers, or you must refrain from using the Licensed Work'.
-
major Rubric 4
odrl:prohibitionapplieddalicc:ChangeLicense for 'All copies of the original and modified Licensed Work, and derivative works of the Licensed Work, are subject to this License.' dalicc:promote for 'This License does not grant you any right in any trademark or logo of Licensor or its affiliates'.
-
major Rubric 5
odrl:dutyappliedcc:Notice for 'You must conspicuously display this License on each original or modified copy of the Licensed Work' and cc:ShareAlike for 'All copies of the original and modified Licensed Work, and derivative works of the Licensed Work, are subject to this License.' Both hang on odrl:distribute, odrl:modify and odrl:derive rather than on the licence as a whole, because the sentence binds copies and derivative works of the Licensed Work and reaches nothing else. The licence requires no source publication, so there is no cc:SourceCode duty.
-
major Rubric 6
dalicc:WarrantyDisclaimerappliedThe disclaimer is quoted verbatim. dalicc:LiabilityLimitation is left out because the text carries no limitation of liability at all, only the warranty disclaimer. Ten further clauses are quoted in dalicc:additionalClauses, including the three Covenants of Licensor that tell a licensor what it may fill in.

major Rubric 7
dalicc:validityTypeapplieddalicc:validityType stays dalicc:perpetual and cc:jurisdiction dalicc:worldwide. The Change Date is a fact about a project that uses the template, not about the template: 'Effective on the Change Date, or the fourth anniversary of the first publicly available distribution of a specific version of the Licensed Work under this License, whichever comes first, the Licensor hereby grants you rights under the terms of the Change License, and the rights granted in the paragraph above terminate.' That clause is quoted instead of being turned into a date. dalicc:terminatesOnBreach is true for 'Any use of the Licensed Work in violation of this License will automatically terminate your rights under this License'; no cure period is offered.
-
gap Rubric 8
dalicc:additionalClausesnoneThe change date and the change licence have no term. The clause is quoted. Proposed terms: dalicc:changeDate, a date after which the licence becomes another one, and dalicc:changeLicense, an object property naming the record the licence turns into. The template leaves both blank, so a record for a project that uses it would carry the filled-in values.
-
gap Rubric 8
dalicc:additionalClausesnoneThe Additional Use Grant has no term: 'The Licensor may make an Additional Use Grant, above, permitting limited production use.' It is the licensor's own text and differs per project. Quoted. Proposed term: dalicc:additionalUseGrant, a literal holding the extra permission a licensor writes into the template.
-
gap Rubric 8
dalicc:fieldOfUseRestrictionnone'Non-production use' has no action term. dalicc:fieldOfUseRestriction is the nearest literal and carries it, following C-UDA-1.0, which uses the same property for 'Computational Use'. Proposed term: dalicc:productionUse as a rule action, so that a record can prohibit it outright instead of naming it in a literal.
-
info Rubric 9
recordnoneThe consistency check of app.services.composer, run against licensedata/dependencygraph/dg_default.ttl, returned no conflicts. cc:ShareAlike hangs on three permissions rather than on the licence as a whole, so the rule about a whole-work share-alike duty beside a relicensing permission does not apply, and dalicc:ChangeLicense is prohibited in any case.
-
major Rubric 10
recordnoneIts nearest sibling in the library is C-UDA-1.0, which also prohibits dalicc:ChangeLicense, carries cc:ShareAlike as a duty on the acts that pass the work on, and names its restriction in dalicc:fieldOfUseRestriction. The difference is that C-UDA-1.0 permits cc:CommercialUse and this record leaves it unstated, and that this licence changes into another licence on a date the licensor sets.

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.

Version 1
Created from the license text on 2026-09-22 (Source-available licences and riders).
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.
