{"id":"Unicode-3.0","title":"Unicode License v3","reviewed_on":"2026-09-15","reviewer":"Giray Havur","text_source":"https://www.unicode.org/license.txt","text_retrieved":true,"verdict":"created","summary":"Models the Unicode License v3 of 2023, which replaced the 2016 data files and software agreement. It is an MIT style grant over data files and software together, so the record follows the MIT record and carries both dcmitype:Dataset and dcmitype:Software as targets. Nothing here is legal advice.","findings":[{"rubric":2,"severity":"minor","field":"odrl:target","description":"The licence covers \"data files and any associated documentation (the Data Files) or software and any associated documentation (the Software)\", so the asset collection carries dcmitype:Dataset next to dcmitype:Software. That is wider than the plain MIT record, which names software only.","action":"applied"},{"rubric":3,"severity":"major","field":"odrl:permission","description":"The grant reads \"Permission is hereby granted, free of charge, to any person obtaining a copy of data files ... to deal in the Data Files or Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, and/or sell copies of the Data Files or Software, and to permit persons to whom the Data Files or Software are furnished to do so\". The closing limb is modelled as odrl:grantUse, which is how the MIT record models the same wording.","action":"applied"},{"rubric":4,"severity":"major","field":"odrl:prohibition","description":"The closing paragraph states \"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 these Data Files or Software without prior written authorization of the copyright holder\", modelled as a dalicc:promote prohibition. No dalicc:ChangeLicense statement is made, following the MIT record: a grant to deal in the work without restriction does not bar relicensing.","action":"applied"},{"rubric":5,"severity":"minor","field":"odrl:duty","description":"The single condition is \"provided that either (a) this copyright and permission notice appear with all copies of the Data Files or Software, or (b) this copyright and permission notice appear in associated Documentation\". Both limbs require the same notice, so cc:Attribution and cc:Notice hang off odrl:distribute, odrl:modify and odrl:derive, and the choice of place is left to the quoted text.","action":"applied"},{"rubric":6,"severity":"minor","field":"dalicc:additionalClauses","description":"The acceptance notice that opens the agreement and the advertising sentence are quoted in dalicc:additionalClauses; the warranty and liability paragraphs are quoted word for word in their own predicates.","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":"major","field":"record","description":"Unicode-3.0 replaced Unicode-DFS-2016 in 2024 and both are modelled in this review group. The deontic models are identical; the 2016 text adds the directory listings that define which files are Data Files and which are Software, and the 2023 text drops them. Two records are justified because the two texts are separately cited, and dalicc:variantKind \"version\" records the chain.","action":"applied"},{"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: \"Permission is hereby granted, free of charge, to any person obtaining a copy of data files and any associated documentation (the \"Data Files\") or software and any associated documentation (the \"Software\") to deal in the Data Files or Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, and/or sell copies.\" The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.","action":"applied"}],"family":"Python, PHP, Unicode and W3C","port_of":null,"variant_kind":"version","notes":"The copyright line of the source carries a copyright sign, which is kept; no long dash appears in either Unicode text."}
