As long as someone can figure out the syntax themselves I don’t think there needs to be an agreed upon syntax. A while back I helped a researcher who wrote to ask-rssac at icann.org <mailto:ask-rssac at icann.org> with trying to figure out which instance they were getting queries from and we ended up just writing the RSO and asking them. That process doesn’t scale well.

There’s a top-level top-level key to the JSON data called “Identifier Naming Convention”. Some RSIs fill this in and some don’t.
<https://root-servers.org/root/B/json/> 

There’s also RFC 7108 to be aware of.
