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.

The record models the three-clause BSD license, adding the endorsement prohibition that distinguishes it from the two-clause variant. It had no link to the license text at all and no warranty disclaimer; both were added from the text.

The review's finding on family consistency: the disclaimer paragraph held both the warranty sentence and the liability sentence. It is split at 'IN NO EVENT SHALL THE COPYRIGHT HOLDER OR CONTRIBUTORS BE LIABLE', as the six new BSD records split it.

permission dalicc:ChangeLicense with duties [dalicc:compliantLicense]Manual edit Permit relicensing on permissive licences; the notice clause is a duty, not a bar. Library convention 15: a licence that asks for no reciprocity and no source code asks only that the notice travels with the copy, which is a duty on the acts it governs and not a bar on putting the copy under other terms. dalicc:ChangeLicense is therefore a permission here, and the prohibition the record carried before is removed. The text reads: "Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: 1. Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.

Version 1
The version this model had before the content review of 2026-09-15.
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.
