The record follows BSD-2-Clause for everything the two share and drops nothing else. Nothing here is legal advice.","findings":[{"rubric":3,"severity":"major","field":"odrl:permission","description":"The grant reads \"Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met\". The record therefore permits reproduce, distribute, modify, derive, display, present, commercial use, derivative works, modified works and the distribution fee, the same set the BSD-2-Clause record carries.","action":"applied"},{"rubric":4,"severity":"minor","field":"odrl:prohibition","description":"The licence has no endorsement clause, so no dalicc:promote statement is made at all: silence about trademarks is not a grant and not a refusal. This departs from the existing BSD-2-Clause record, which permits dalicc:promote although the two-clause text is equally silent. dalicc:ChangeLicense is prohibited, as in every other BSD record. (Corrected on 2026-09-15 by the verification pass: see the rubric 3 finding on relicensing below.)","action":"applied"},{"rubric":5,"severity":"major","field":"odrl:duty","description":"The retention conditions are the whole content of the licence. cc:Attribution and cc:Notice hang off odrl:distribute, odrl:modify and odrl:derive, because the text requires the copyright notice, the list of conditions and the disclaimer to travel with every redistributed and every modified copy.","action":"applied"},{"rubric":6,"severity":"minor","field":"dalicc:WarrantyDisclaimer","description":"The single disclaimer paragraph of the BSD family carries two distinct clauses. This record splits it at the sentence boundary: the warranty sentence goes to dalicc:WarrantyDisclaimer and the \"IN NO EVENT SHALL\" sentence to dalicc:LiabilityLimitation, both verbatim. The existing BSD-2-Clause, BSD-3-Clause and BSD-4-Clause records keep the whole paragraph in dalicc:WarrantyDisclaimer and carry no dalicc:LiabilityLimitation; those records were not edited, and the divergence is reported for the consolidation.","action":"applied"},{"rubric":7,"severity":"info","field":"cc:jurisdiction","description":"The text names no legal system and sets no term, so cc:jurisdiction is dalicc:worldwide and dalicc:validityType is dalicc:perpetual.","action":"applied"},{"rubric":9,"severity":"info","field":"record","description":"The consistency check of app.services.composer with the dependency graph dg_default returned an empty conflict list.","action":"none"},{"rubric":10,"severity":"info","field":"record","description":"Follows licensedata/licenses/BSD-2-Clause.ttl. The only modelled difference is that the one-clause text has no binary-form retention condition; since the library expresses both conditions with the same cc:Attribution and cc:Notice duties, the two records carry the same duty set, and the difference is visible only in the quoted clause text.","action":"none"},{"rubric":3,"severity":"major","field":"odrl:permission","description":"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 earlier reading wrote 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.","action":"applied"}],"family":"BSD variants","port_of":null,"variant_kind":null,"notes":"cc:legalcode points at the FreeBSD source file that SPDX names as the canonical location of this wording. The disclaimer uses the typewriter quotation marks of the original (``AS IS''), which are kept verbatim."}
