I have Peertube running on a subdomain, tube.example.xyz
We would like usernames not to require the subdomain.
For example we would like people to be able to follow user@example.xyz instead of User@tube.example.xyz
Is this possible?
As a followup or additional question. Is the above possible if I were to implement similar functionality for other Federated netowrks as well.
For example, if have Mastodon on one subdomain and Peertube on another. Could both Mastodon and peertube be followed with username@example.xyz instead of username@subdomain.example.xyz, or will they conflict since both use ActivityPub?
Your question is akin to asking if one could send a mail to joe. Mail has users on domains, and so is ActivityPub. This is a common choice for decentralized applications, since the other way is to have a resevable resource, a difficult problem for decentralized applications that is represented by Zooko's triangle - Wikipedia.
Usernames will IMHO always require their domain part.
Why?
They will conflict, since they have different canonical URIs and keys singning their activities.
Thank you for taking the time to answer this @rigelk
As to « why drop the subdomain »:
Since I have mastodon on the same domain too and Mastodon does support dropping the subdomain from the username I just think it would be a little more convenient if people could use the same username@TLD to follow me on Peertube and Mastodon
Mastodon uses an entry under .well-known/host-meta
As is decribed here to drop subdomain from username
I was wondering if something similar is possible with Peertube
If not maybe I will switch to a mydomain.tube setup instead of tube.mydomain.xyz just to allow for a (minimally) shorter username
Thank you for all your great work on Peertube @rigelk. I love it!
