Clauses

Additional clauses

You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.

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 content review of 2026-09-15 added 1 identification detail, 1 permission and 1 statement, recorded the relation to the record this one was adapted from and recorded the review state. Later changes brought it in line with its family and its text in the verification of 2026-09-15, corrected it against its text on 2026-09-23 and 2026-09-24, left endorsement to the default rule of the core dependency graph, recorded which sentence of the text each statement rests on, named the license the record itself is published under and recorded the licenses a work under it may be released under.

    • added dalicc:orLaterVersionOption "false"^^xsd:boolean

      Review decision Review decision 6: the four GNU records model the '-only' reading, so the or-later option is recorded as false rather than left unsaid.

    • added dalicc:reviewStatus dalicc:Reviewed

      Review state Every record records how far it has come in the editorial workflow and when it was last checked against the legal text.

    • added permission dalicc:chargeDistributionFee

      Review finding Section 4 of the GPL, which the Lesser GPL incorporates, states: "You may charge any price or no price for each copy that you convey." Added the missing dalicc:chargeDistributionFee permission.

    • added dalicc:curePeriod "30 days"

      Manual edit The licence incorporates the terms of the GNU General Public License version 3, and the record now states what those sections say. Section 8: "Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License", with reinstatement if "you cure the violation prior to 30 days after your receipt of the notice". Section 11: "Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims".

    • removed prohibition dalicc:promote

    • changed permission dalicc:chargeDistributionFee

      was permission dalicc:chargeDistributionFee

      Manual edit The statement now quotes the sentence of the licence text it rests on: "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."

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.
