It adds the advertising bar that MIT does not have, so dalicc:promote is prohibited and the clause is also quoted in dalicc:additionalClauses.","findings":[{"rubric":3,"severity":"major","field":"odrl:permission","description":"The grant reads: \"to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so\". The list omits sublicense, which MIT has, so the record carries odrl:grantUse for the clause about persons to whom the software is furnished but no dalicc:sublicense. Selling copies supports dalicc:chargeDistributionFee.","action":"applied"},{"rubric":5,"severity":"major","field":"odrl:duty","description":"The condition is that the copyright notices and the permission notice appear in all copies and in supporting documentation: cc:Attribution and cc:Notice on distribute, modify and derive.","action":"applied"},{"rubric":4,"severity":"major","field":"odrl:prohibition","description":"The text reads: \"Except as contained in this notice, the name of a copyright holder shall not be used in advertising or otherwise to promote the sale, use or other dealings in this Software without prior written authorization of the copyright holder.\" That is dalicc:promote as a prohibition. dalicc:ChangeLicense is prohibited because the text requires the license itself to travel with every copy, which is the reading IscLicense and BSD-3-Clause take of the same clause. The MIT record does not carry the prohibition although its text has the same requirement, so the library is not uniform here. (Corrected on 2026-09-15 by the verification pass: see the rubric 3 finding on relicensing below.)","action":"applied"},{"rubric":6,"severity":"minor","field":"dalicc:additionalClauses","description":"The advertising paragraph is quoted in dalicc:additionalClauses as well as modelled as a prohibition, because it also limits what the notice itself allows, which the prohibition alone does not say.","action":"applied"},{"rubric":7,"severity":"info","field":"cc:jurisdiction","description":"The text names no legal system and no term, so cc:jurisdiction is dalicc:worldwide and dalicc:validityType is dalicc:perpetual.","action":"none"},{"rubric":2,"severity":"info","field":"odrl:target","description":"One odrl:AssetCollection of dct:type dcmitype:Software, following MIT.

The text reads: \"Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the \"Software\"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, provided that the above copyright notice(s) and this permission notice appear in all copies of the Software and that both the above copyright notice(s) and this permission notice appear in supporting documentation.\" The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.","action":"applied"}],"family":"Permissive: MIT, ISC and BSD-like","port_of":null,"variant_kind":null,"notes":"Modelled from the SPDX plain text. cc:legalcode is the ICU project URL SPDX lists; the text has no steward named in it, so there is no dct:publisher."}
