This looks like an interesting idea. Having skimmed through the Whitepaper, I've ended up with far more questions than answers !

I think the key is going to be ensuring that the data is more accurate than that held by traditional ratings agencies, which means data creators need to be selected for quality rather than just who feels like paying for an NFT.
On a side note, I think it's sad that every project has to have it's own token. If projects that are aimed to attract non-Hive customers all agreed to use HIVE or HBD it might help build momentum for wider adoption. Rather than customers buying whatever token has been issued exclusively by a single project (or paying with fiat), it would be good if fiat payment would automatically create them a HIVE wallet at the same time as they were sent an automated email or link promoting all the other things their new HIVE tokens give them access to.
