Comment Despite the name, this does not appear to be an international standard in any normal sense; it is not undergoing ISO review as far as I could tell, for example, or has any associated standards body sponsoring it. There's an existing (similar?) "standard" for digital content with the name "International Standard Content Code (ISCC)" - see https://iscc.codes/ - but that one does appear to be under review by ISO: "ISO/TC 46/SC 9 (Identification and description) has accepted the International Standard Content Code as a preliminary work item and created a new working group (WG 18 - Digital-Content-Based Identification).". I think this ISCN proposal should not be acted on until we know more about it and its relation to other such potential codes or identifiers. ArthurPSmith (talk) 18:52, 13 December 2021 (UTC)[reply]
Comment another question is if Commons wants their system of providing metadata to be supplanted with the above. --- Jura 13:11, 14 December 2021 (UTC)[reply]
