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)

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.
Cure period: 30 days
Or later version option: No
Reciprocity scope: the whole of the work, and, where the functionality is offered as a service, the Service Source Code, which includes every program used to make the service available
Terminates on breach: Yes

Review

Written from the license text by: Giray Havur
Written on: 2026-09-22
Second review: not yet done
Record changed since this review: yes (version 2, 2026-09-24)
Findings: 14 recorded, 11 applied to the record, 0 proposed

The record models the Server Side Public License, version 1. The text is the GNU General Public License version 3 with one section replaced: where the GPL asks for the source of the covered work, section 13 asks anyone who offers the functionality as a service for the Service Source Code, which reaches every program used to run that service. That is why the licence is not accepted as an open source licence, and the record says so by carrying the network trigger and the reciprocity scope the text states.

14 findings

info Rubric 1 spdx:licenseId applied

File name, record identifier, SPDX identifier and IRI local name agree. cc:legalcode points at the publisher's own page and dct:source at the SPDX entry. dct:publisher is MongoDB, Inc., which the copyright line and section 14 name.
info Rubric 2 odrl:target applied

dcmitype:Software only, following AGPL-3.0, whose text this one is built on.
major Rubric 3 odrl:permission applied

Section 2 affirms 'your unlimited permission to run the unmodified Program, subject to section 13', sections 4 to 6 permit conveying verbatim copies, modified sources and object code, and section 11 grants a patent licence. That gives odrl:reproduce, odrl:distribute, odrl:modify, odrl:derive, odrl:display, odrl:present, cc:DerivativeWorks, dalicc:ModifiedWorks, cc:CommercialUse, dalicc:chargeDistributionFee for 'You may charge any price or no price for each copy that you convey' and dalicc:patentGrant.
major Rubric 3 dalicc:networkUseTrigger applied

dalicc:networkUseTrigger carries a cc:SourceCode duty for section 13: 'If you make the functionality of the Program or a modified version available to third parties as a service, you must make the Service Source Code available via network download to everyone at no charge, under the terms of this License.' CAL-1.0 uses the same term for the same kind of trigger. AGPL-3.0 does not carry it, which is a difference between the two records rather than between the two texts, and it is proposed below.
major Rubric 4 odrl:prohibition applied

dalicc:ChangeLicense for section 5(c), 'This License gives no permission to license the work in any other way'. dalicc:sublicense for section 2, 'Sublicensing is not allowed; section 10 makes it unnecessary.' dalicc:addLimitation for section 10, 'You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License.' dalicc:applyTechnicalProtectionMeasures for section 3. dalicc:patentRetaliationTermination for the litigation sentence of section 10. dalicc:promote for section 7(d) and 7(e), which let a licensor limit the use of its names for publicity and decline to grant trademark rights, the same reading AGPL-3.0 takes.
minor Rubric 4 odrl:grantUse applied

Section 10 says 'Each time you convey a covered work, the recipient automatically receives a license from the original licensors', which would ordinarily give odrl:grantUse. It is left out, because the dependency graph holds dalicc:sublicense owl:sameAs odrl:grantUse and section 2 forbids sublicensing, so asserting both would report a conflict. CAL-1.0 is modelled the same way for the same pair of sentences. The clause is quoted instead.
major Rubric 5 odrl:duty applied

cc:ShareAlike is licence-wide for section 5(c), 'You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy', which is the whole-work copyleft shape. cc:Attribution, cc:Notice and cc:SourceCode hang on odrl:distribute, odrl:modify and odrl:derive, and dalicc:modificationNotice is added on the last two for section 5(a). The network-use trigger carries its own cc:SourceCode duty, because the source it asks for is wider than the source conveying asks for.
major Rubric 6 dalicc:WarrantyDisclaimer applied

Sections 15 and 16 are separate, so each goes into the property that names it, and section 4's fee sentence is dalicc:WarrantyOrLiabilityAcceptance, exactly as in AGPL-3.0. Fifteen further clauses are quoted in dalicc:additionalClauses, including both paragraphs of section 13 and the definition of Service Source Code.
major Rubric 7 dalicc:validityType applied

dalicc:validityType is dalicc:perpetual for section 2, 'All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met.' dalicc:orLaterVersionOption is false, because this record models version 1 only, while section 14 lets a program opt into later versions; that sentence is quoted. dalicc:terminatesOnBreach is true for section 8 and dalicc:curePeriod is '30 days' for the first-time cure it offers. The text names no governing law.
gap Rubric 8 dalicc:sourcePublicationPeriod none

Section 13 says the Service Source Code must be available 'via network download to everyone at no charge' but gives no period, so dalicc:sourcePublicationPeriod is left out rather than filled with a guess. The clause is quoted. Proposed term: dalicc:serviceSourceScope, an annotation for the set of programs a network-use trigger reaches, which here is wider than the covered work and has no counterpart in any other record.
info Rubric 9 record none

The consistency check of app.services.composer, run against licensedata/dependencygraph/dg_default.ttl, returned no conflicts. The whole-work cc:ShareAlike duty sits beside a prohibited dalicc:ChangeLicense, which is the shape the check expects of a copyleft licence.
major Rubric 10 record none

Against AGPL-3.0, which shares most of this text, the record adds dalicc:networkUseTrigger with a source duty, dalicc:reciprocityScope, dalicc:sublicense, dalicc:addLimitation, dalicc:applyTechnicalProtectionMeasures, dalicc:patentRetaliationTermination, odrl:display and odrl:present, and it carries a cure period. The clauses behind the statements AGPL-3.0 lacks are in both texts, so those are proposals for AGPL-3.0 rather than differences between the licences; the network trigger and the termination terms were applied to AGPL-3.0 on 2026-09-23 and the rest stay proposals.
minor Rubric 4 odrl:prohibition applied

dalicc:promote was prohibited and no sentence of this text supports it. The statement was the library's reading of a legal default, that a copyright licence which says nothing about endorsement grants no right to it, and it sat in 519 of 581 records as a house convention. That reading is now an adopted dalicc:DefaultRule of the core dependency graph, which supplies it to every licence that is silent about the action, so a compatibility check reaches the same answer and the record states only what the text states. Removed on 2026-09-23; see section 13 of docs/LICENSE_REVIEW.md.
minor Rubric 6 dalicc:WarrantyOrLiabilityAcceptance applied

dalicc:WarrantyOrLiabilityAcceptance held the whole sentence of Section 4, "You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee." Its first half is the permission to charge for a copy, which the record states as dalicc:chargeDistributionFee, and not a warranty clause. The literal now quotes only the second half, "you may offer support or warranty protection for a fee".

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 2 current2026-09-24 Giray Havur

The changes since version 1 left endorsement to the default rule of the core dependency graph, recorded which sentence of the text each statement rests on, corrected it against its text on 2026-09-24 and named the license the record itself is published under.
