My adventure in implementing #ActivityPub:

With the support of #ChatGPT I roughly understand how the protocol works and have a working implementation for at least #WebFinger and a json-LD conforming profile page.

There are some gaps in the structures, e.g. I can lookup my own user profile, @andreas@pramari.de, from microblog.pub, but not from mastodon.social yet. Obviously following does not yet work, although I have the data structures in place to store followers by profile.

Next up is the implementation of a mechanism to follow.
