How to implement ActivityPub for a blog that has multiple authors?

[johnny]

Hey there, I recently got into ActivityPub, started using Mastodon and thought that’d it be cool to integrate ActivityPub into my personal blog. I want to write a simple blogging software from scratch to experiment and tinker with the protocols. I was able to understand most of the ActivityPub spec, though I haven’t found a good way to model the following scenario:

• There is a blog actor that people can follow to see new blog posts
• Possibly multiple people can post to the blog via ActivityPub (they act as separate authors - I don’t want them to share the “blog actor” credentials or something)

In short, I’m wondering how I can make an actor that is a union of other actors. The best I could come up with so far is automatic reposting. But that would introduce a redundancy if the author actors address their posts to the Public audience for example. And I would want to have a single comment section for a post etc.

Group would work, although actor types don’t really matter that much

Use the Announce activity, to have the blog actor reshare the article from the post author natively that way

I suggest you look at Plume which implements exactly this.
