Wishing there were a standard data format for #activitypub services. If I want to change the software my mail server runs, I know I can get the data transferred in mbox (or maildir) format. If I want to change my gitweb presenter, the repos are there. To change from ActivityPub server program A to B, then unless A is Mastodon and B is Pleroma it appears I'm basically out of luck.
Someone tell me different?
https://microblog.pub/ is abandoned, as far as I can tell (and no, I don't have time to maintain a fork)
@dan (tl;dr version: ActivityPub is a protocol that passes around JSON-LD objects. Any project doing things "the right way" has an export tool, and that export tool gives you a flat JSON file, and an import tool that accepts it.
As for "does anything actually do things the right way", I don't know about Pleroma's import/export facilities, but Mastodon provides at least the export tools at the account level. It exports accounts as a JSON-LD object containing the entire ActivityPub actor. It's one of the very few things Mastodon didn't get all Not-Invented-Here about.
@firstname.lastname@example.org that makes sense and I've found those objects in my database. It's the import part I'm missing - I can't just post my entire notes history to the new server's outbox or it'll send them on to all the original recipients
