Summarized Comments: -------- The aim is to use decentralised technologies to provide persistent and interoperable landscapes of FDOs which indeed offers reasons for interesting debates. This very good paper should have emphasised a little more the challenges and possible limitations of the approach and relate it to other approaches relying for example on sustainable and certified repositories as custodians of data. DIDs are an interesting concept, but it led to a burst of different schemas managed by communities which will hardly survive.
