@KiChjang, this is the RFC, the possibility of which we spoke of long ago in Matrix. Could you please take a look? @franciscoaguirre @xlc Please take a look as well 🙏 |

| 3. Are the proposed metadata format and operations general enough? | ||
| 4. Could the proposed instruction set be reduced without losing both generality and convenience? | ||
| 5. How one could easily pay for the execution of the `ModifyMetadata`, `ApproveMetadataModification`, and `NoteMetadataModificationApproval`? | ||
| 6. How to make the `MetadataMap` bounded? The same question for `MetadataKeys`. |
There was a problem hiding this comment.
the simply way is define max key length, max value length and max number of keys
another ways is not define anything here, but depends on the overall XCM size limit

This is a preliminary version of an RFC describing the metadata communication of asset collections and asset instances (i.e., NFTs).
It is by no means final. Instead, it provides a base for a more formal discussion.
Improvements, discussions, and any other input are enormously appreciated!
The preliminary version of the RFC was requested to be posted during the discussion of the Unique Network's XCM NFT proposal.
The RFC is meant to evolve over time.
RFC Summary
The proposed change provides a general way of communicating metadata of assets and asset instances between consensus systems via XCM.
Currently, there is no standard, general, and easy way to do so.
Communicating metadata enables new cross-consensus use cases for NFTs and might simplify the registration of foreign assets (both fungible and nonfungible).
