Hey, thanks for the submission! Can you elaborate on how you think this could integrate into the existing NFT standard? Any upgrade should probably be backwards compatible with the existing standard. If not, can you explain why?

and can you also provide more detail about why you chose to require each fields in this specification?

Thank you!

I don't actually see any sample code. Could you include an example implementation?
Also, how would you expect projects to be interoperable with this standard? We would ideally need some sort of standard interface that 3rd parties could use to interact with projects that use these

Can I add example code and tests in subsequent milestones? This pr is the result of my Milestone 1.

[joshuahannan]

Good point. You can add sample code in future milestones. We can probably merge this. 👍
