This reminds me of the Contact Info Sharing Specification.

There are details on the specification at:

https://github.com/nusenu/ContactInfo-Information-Sharing-Specification

You can also automatically generate the Contact Info string using this
tool (I've not checked this out yet):

https://torcontactinfogenerator.netlify.com/

Currently Tor Metrics doesn't do anything with this data (except archive
it) because not that many relay operators are using it, but if more
operators were sharing the information using this specification then it
would help Metrics understand the network better, and help with research
projects that want to better understand the network to improve path
selection too.

I've just set the Contact Info on my two relays to conform to this
specification (might take an hour or two to show up on Relay Search).

Just checking now, only 70 relays use this specification, which is
approx 1% of the running relays. If we can get this up to 4-5% then Tor
Metrics may look more closely at this.

Thanks,
Iain.
