Hi pfefferle@mastodon.social, I was just curious why activitypub.blog@activitypub.blog was a user and not a group on NodeBB, so I checked out its AP representation on BrowserStack.
This stood out:
...
"generator": {
"type": "Application",
"implements": {
"href": "https://datatracker.ietf.org/doc/html/rfc9421",
"name": "RFC-9421: HTTP Message Signatures"
}
},
...
I thought "how would you be able to represent multiple implementations if implements is an object?
It looks like it is supposed to be an array, according to FEP 844e.
As an aside, I guess not all WP actors are groups? I feel like we've had this conversation before though hehe.
