Hello Sebastian, thanks for the pointers, this is indeed a very interesting project that tie in neatly with what we want to achieve in Wikidata. I didn't read your paper in detail, but merely skimmed it, so I hope I have a reasonable understanding of your proposal.
We have not yet written down the use cases, and we are aware that this still needs to happen. I do think that your approach - especially with the context-hash-based URIs - is very promising. We aim to start with a simple website-level scope for Web references, but personally I would be very happy if we could move down to the more fine-grained level that your tools support in the first year already, down to the very sentence that supports a statement in Wikidata. If we get this far, your approach seems like a very strong contender for representing this. Just a few questions - as you note, it is easier if we all use the same standards, and so I want to ask about the relation to other related standards: * I understand that you dismiss IETF RFC 5147 because it is not stable enough, right? * what is the relation to the W3C media fragment URIs? Did not find a pointer there. * any plans of standardizing your approach? We would strongly prefer to just use a standard instead of advocating contenders for one -- if one exists.
