Ah, I see, so you are talking about this.

Of course it is nice if things get auto-generated, but doing it yourself, both in code and documentation should never be excluded as an option.

Could you elaborate on this:

it’s not really possible to document and validate that an endpoint needs to have at least one of something

In what sense it is not possible, as I can easily see it done in the code?

thank you!

Do you have more information on how it supports crossposting with Mastodon? As far as I know, Friendica supports its protocol, but that’s about it.

Unfortunately Diaspora does not use the ActivityPub protocol and doesn’t even bridge to it. They have made the deliberate choice to not ever have a sizeable community.
