The legal text was read in Japanese and the permissions, prohibitions and duties all follow from the grant and restriction sections of the port. Corrections applied: dct:source, and the split of the warranty disclaimer from the limitation of liability. What remains are proposals that touch the whole Creative Commons family rather than this record: the express prohibition of sublicensing, and the asset types.","findings":[{"rubric":1,"severity":"minor","field":"dct:source","description":"The record carried cc:legalcode but no dct:source.

Creative Commons licences are media neutral, and this port grants the rights in all media and formats now known or later devised. Aligning the ports with the parents is a single library wide decision covering every Creative Commons port, so it is left as a proposal rather than applied in thirty six records alone.","action":"proposed","change":"odrl:target [ a odrl:AssetCollection ;\n        dct:type dalicc:CreativeWork ,\n            dcmitype:Dataset ] ;"},{"rubric":3,"severity":"info","field":"odrl:permission","description":"Every modelled permission is supported by the grant. Article 3 grants a licence in all countries, royalty free, non-exclusive and continuing for the term of Article 7(b), and it enumerates the neighbouring rights in performances, phonograms, broadcasts and cable broadcasts as covered subject matter. The Japanese port also moves the downstream offer to recipients into its own Article 4, where the other ports keep it in the miscellaneous section. The grant covers reproduction, incorporation into collections, distribution, public display, public performance and communication to the public, and the creation and reproduction of derivative works, which the record models as odrl:reproduce, odrl:distribute, odrl:display, odrl:present, odrl:derive and cc:DerivativeWorks.","action":"none"},{"rubric":4,"severity":"major","field":"odrl:prohibition","description":"The licence forbids sublicensing and the record does not say so. Article 5: the licensee may not grant a further licence in the work. The vocabulary already has dalicc:sublicense, but it is used by no record in the library and its skos:note says so, and the same sentence stands in every Creative Commons 2.0 and 3.0 record, so adding it to thirty six ports alone would split the compatibility behaviour of one family. Proposed as one library wide correction, together with an update of the vocabulary note.","action":"superseded","superseded_by":2,"change":"odrl:prohibition [ a odrl:Prohibition ;\n        odrl:action dalicc:sublicense ] ;"},{"rubric":4,"severity":"info","field":"odrl:prohibition","description":"dalicc:ChangeLicense is prohibited, which the licence supports: the licensee may offer the work only under the terms of this licence and may not offer or impose terms that alter or restrict it. dalicc:promote is prohibited, which rests on the reservation of all rights not expressly granted and on the trademark paragraph of the Creative Commons notice, not on a clause of the licence body.","action":"none"},{"rubric":5,"severity":"info","field":"odrl:duty","description":"The attribution and notice duties are present and supported: the licence requires a copy of, or the URI for, the licence with every copy, that all notices referring to the licence and the warranty disclaimer be kept intact, and that credit be given to the author. Article 5 owes credit to the original author and to the performers, with the title, the licensor URI and, for a derivative work, a credit identifying the use made of the work. The duties hang on odrl:distribute, odrl:modify and odrl:derive, which matches the licence, since the duties are triggered by making the work public rather than by private use.","action":"none"},{"rubric":6,"severity":"minor","field":"dalicc:WarrantyDisclaimer","description":"The Japanese port has no separate disclaimer section: Article 6 is headed as the limitation of liability and its first paragraph is the warranty disclaimer, its second the limitation of liability.

Article 5: the licensee may not use the work or a derivative work with technological protection measures that control access to or use of the work in a way that conflicts with the licence.

What differs is the jurisdiction, the language of the legal text and the clause texts, and the version specific clauses of 2.0 that the model does not carry, chiefly the express prohibition of sublicensing, the technological measures clause and the royalty collection arrangements.

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.

The 2.0 text differs from 4.0 in substance as well: it prohibits sublicensing expressly, it has no thirty day cure period for a breach, it has no sui generis database rights clause, and it settles the royalty collection question per jurisdiction. None of that is visible in the model. Nothing in this review is legal advice."}
