The record said the opposite of the text on passing rights on, and used cc:ShareAlike as a permission. Both were corrected.","findings":[{"rubric":3,"severity":"major","field":"odrl:prohibition","description":"The grant runs \"to use, reproduce, display, distribute, execute, and transmit the Software, and to prepare derivative works of the Software, and to permit third-parties to whom the Software is furnished to do so\". The record prohibited odrl:grantUse, the exact opposite. Removed the prohibition and added the permission.","action":"applied","change":"# removed\nodrl:prohibition [ a odrl:Prohibition ;\n        odrl:action odrl:grantUse ] ;\n# added\nodrl:permission [ a odrl:Permission ;\n        odrl:action odrl:grantUse ] ;\n"},{"rubric":5,"severity":"major","field":"odrl:permission","description":"cc:ShareAlike was modelled as a permission carrying a cc:Notice duty. cc:ShareAlike is a duty term: as a permission it means nothing the general grant does not already say, and the dependency graph treats an asserted share-alike as contradicting odrl:grantUse, which is why the record had to prohibit sublicensing to stay consistent. The Boost license imposes no share-alike. Removed. Flagged by the family conventions checked before the review.","action":"applied","change":"# removed\nodrl:permission [ a odrl:Permission ;\n        odrl:action cc:ShareAlike ;\n        odrl:duty [ a odrl:Duty ;\n                odrl:action cc:Notice ] ] ;\n"},{"rubric":5,"severity":"minor","field":"odrl:duty","description":"The notice condition has an exception the model cannot show: it does not apply \"unless such copies or derivative works are solely in the form of machine-executable object code generated by a source language processor\". The cc:Notice duty on distribute is therefore stricter than the text for binary-only distribution.","action":"none"},{"rubric":4,"severity":"minor","field":"odrl:prohibition","description":"dalicc:addStatement and dalicc:promote remain prohibited with no support in the text.

The statement was the library's reading of a legal default, that a copyright licence which says nothing about endorsement grants no right to it, and it sat in 519 of 581 records as a house convention. That reading is now an adopted dalicc:DefaultRule of the core dependency graph, which supplies it to every licence that is silent about the action, so a compatibility check reaches the same answer and the record states only what the text states.
