There is a crate which maintained by @nutomic@lemmy.ml: https://crates.io/crates/activitypub_federation
I believe it should be compatible with other projects 馃
馃憜 It鈥檚 literally what Lemmy is built upon @Asudox@lemmy.world
Thanks. Will check it out.
Harder than implementing RSS. Less hard than writing Linux from scratch. Where it lays in the middle depends a shitload on your requirements. How much you want to federate (a blog post VS conversations for instance), do you try for exact compatibility with existing services VS using a different activity type, is it one way or bidirectional, how does it need to scale, etc.
I don鈥檛 know of a generic library you can use so you鈥檇 need to read and understand the spec.Harder than implementing RSS.
I wouldn鈥檛 be so sure about that. RSS is a ridiculously complex standard and almost nobody gets it right. Good chance you鈥檒l be back over and over to fix bugs and then, when you have more data in your database, you鈥檒l be doing it all over again after refactoring things to improve performance and causing more bugs.
Bidirectional.
It probably will only federate:
- Communities that are created
- Posts that are created
- Comments that are created
- Deletion of posts, users and comments
- Modlog for the action mentioned above
It depends
