why does zora use ipfs:// IANA scheme?

[TimDaub]

• I know this is probably not the right repository
• When crawling zora contracts at neume.network, I'm finding that many URIs are in the format of ipfs:// and so naively I've assumed that this is an IANA-official format. I even remember @jbenet talking about it years ago
• But I looked into the IPFS code briefly and I couldn't find any indication that indeed the IANA ipfs:// scheme is supported: returns false for a valid ipfs url/path! ipfs-shipyard/is-ipfs#48 (comment)
• The is-ipfs readme further confirms this: https://github.com/ipfs-shipyard/is-ipfs#usage
• but IANA has a definition: https://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml
• But I saw in your code that you're replacing it with the gateway location:

  nft-hooks/src/fetcher/UriUtils.ts

  Line 5 in 6f0b963

  return url.replace('ipfs://', ZORA_IPFS_GATEWAY);

• So are you doing this because the official ipfs https client doesn't support the ipfs:// IANA scheme?

We're doing this in NFT hooks since browsers cannot handle ipfs:// URI schemes with a gateway natively.

The ipfs:// scheme isn't IANA but is supported by most all major NFT marketplaces and recommended as a best-practices thing.
