Thanks for the link to this interesting article.
Looking at it I found a lot of material on Digital Identifiers of Objects
(DIOs), but no mention at all of Identifiers for Digital Objects (IDOs),
so I think it could be interesting for this list to look at the following
article that explains the distinction between DIOs and IDOs in details:
Roberto Di Cosmo, Morane Gruenpeter, Stefano Zacchiroli
“Identifiers for Digital Objects: the Case of Software Source Code Preservation”
iPRES 2018 – 15th International Conference on Digital Preservation, 2018
You may also look at that is a metaresolver quite similar to, with a shorter prefix 🙂
