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.

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.

Review

Status

Verdict

Record changed since this review
yes (version 2, 2026-09-24)
Findings
7 recorded, 3 applied to the record, 2 proposed

The record models the Microsoft Public License correctly in substance: attribution and notice duties from condition 3(C), a trademark prohibition from 3(A), and the licensing condition of 3(D) quoted in dalicc:additionalClauses and modelled as dalicc:ChangeLicense with a compliance duty. The SPDX id and the warranty disclaimer were missing. The patent grant and the patent retaliation have no vocabulary term.

7 findings

  • minor Rubric 1 spdx:licenseId applied

    Added MS-PL; the title matches the SPDX name exactly.

  • minor Rubric 6 dalicc:WarrantyDisclaimer applied

    Condition 3(E) is a warranty disclaimer and was not recorded. Added, quoted.

  • gap Rubric 8 vocabulary none

    Section 2(B) grants a patent license ("each contributor grants you a non-exclusive, worldwide, royalty-free license under its licensed patents to make, have made, use, sell, offer for sale, import, and/or otherwise dispose of its contribution") and condition 3(B) terminates it if the licensee brings a patent claim. Neither can be expressed. Proposed: dalicc:patentGrant, dalicc:patentRetaliationTermination.

  • minor Rubric 5 odrl:duty proposed

    Condition 3(D) is a source-form reciprocity clause: "If you distribute any portion of the software in source code form, you may do so only under this license by including a complete copy of this license with your distribution." The record expresses it only through the compliance duty on dalicc:ChangeLicense. A cc:ShareAlike duty restricted to source form would be closer, but the vocabulary cannot restrict a duty to one distribution form.

  • info Rubric 4 odrl:prohibition none

    dalicc:promote is prohibited and condition 3(A) supports it: "No Trademark License- This license does not grant you rights to use any contributors' name, logo, or trademarks."

  • minor Rubric 1 dct:publisher proposed

    dct:publisher is the placeholder "N.N." while cc:attributionName says "Microsoft".

  • major Rubric 10 record applied

    Standard-license addition of 2026-09-15, decision 9: the record was corrected against its new siblings and versioned. The review's finding on family consistency: dct:publisher was the placeholder 'N.N.' and the record made no patent statement although section 2(B) grants 'a non-exclusive, worldwide, royalty-free license under its licensed patents' and section 3(B) ends that grant on a patent claim, exactly as the new MS-RL record models them.

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 clause text and 1 identification detail and recorded the review state. Later changes brought it in line with its family and its text in the verification of 2026-09-15, recorded which sentence of the text each statement rests on and named the license the record itself is published under.

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.
