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.

Alternative condition set: Section 3 lets the licensee satisfy the source-code condition for object code in any one of three listed ways.
Or later version option: Yes
Sublicense survival: Yes
Terminates on breach: Yes

Clauses

Warranty disclaimer

BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

Limitation of liability

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Accepting warranty or additional liability

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

Additional clauses

If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the simplest and most usual way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this General Public License.

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: 11 recorded, 9 applied to the record, 0 proposed

The record models the "or later" form of the first version of the GNU General Public License. Its legal text is the same document that GPL-1.0-only models, so the deontic model is that record statement for statement. What the identifier adds is the option section 7 gives the licensee to follow version 1 or any later version the Free Software Foundation publishes, which in practice means GPL version 2 or version 3.

11 findings

info Rubric 1 spdx:licenseId applied

File name, record id, SPDX identifier and the local name of the IRI are all GPL-1.0-or-later. The deprecated short form GPL-1.0+ is carried as a dct:alternative so that a search for it reaches this record.
major Rubric 10 dalicc:variantOf applied

The record copies GPL-1.0-only statement for statement. Five things differ: the identifier, dct:title, dct:alternative, dalicc:orLaterVersionOption (true here, false there) and the pair dalicc:variantKind "version-option" with dalicc:variantOf dalicclib:GPL-1.0-only. Everything else, including the three quoted clauses and the four statements that set the pair apart from the GPL version 2 records, is carried over unchanged.
major Rubric 7 dalicc:orLaterVersionOption applied

Section 7 is the clause the flag stands for: "If the Program specifies a version number of the license which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation." The same section adds that where the program names no version at all, "you may choose any version ever published by the Free Software Foundation". cc:jurisdiction stays dalicc:worldwide and dalicc:validityType stays dalicc:perpetual.
major Rubric 3 odrl:permission applied

The permissions are those of the base record and come from the same sentences: section 1 (verbatim copies of the source, and a fee for the physical act of transferring a copy), section 2 (modification and distribution of the modified work) and section 3 (object code or executable form).
major Rubric 5 odrl:duty applied

cc:ShareAlike is a duty of the licence itself, from section 2(b), and the attribution, notice and source-code duties hang on distribute, modify and derive, with dalicc:modificationNotice on modify and derive from section 2(a). Nothing moved when the model was copied.
major Rubric 4 odrl:prohibition applied

The four prohibitions of the base record are kept: dalicc:ChangeLicense from section 2(b), dalicc:addLimitation from section 6, dalicc:sublicense from section 4, and dalicc:promote, which is the library-wide default and is not supported by this text.
info Rubric 6 dalicc:additionalClauses applied

The warranty disclaimer of section 9, the limitation of liability of section 10, the fee and warranty sentence of section 2(d) and the three quoted clauses (sections 2(c), 4 and 6) are byte for byte the literals of GPL-1.0-only, because the text is the same document.
info Rubric 2 odrl:target applied

The asset collection carries dcmitype:Software, as in the base record.
info Rubric 9 record none

The consistency check of app.services.composer, run with licensedata/dependencygraph/dg_default.ttl, reports 0 conflicts for this record.
gap Rubric 8 dalicc:additionalClauses none

The gaps are those of the base record: the interactive announcement of section 2(c), for which no duty action exists (proposed term dalicc:interactiveNotice), and the automatic downstream licence of section 6, which dalicc:downstreamOffer nearly covers but which asks nothing of the licensee. Both are quoted in dalicc:additionalClauses.
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.

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 and named the license the record itself is published under.
