why so many apps for lemmy but none for kbin?
I understand there might be a need to develop different server to client APIs if the services that implement activity pub are very different (lemmy / mastodon). But lemmy and kbin are basically the same shit in different colours.This would be a good case to use / reuse / develop a standard API for server-client communications, I would think so.
I agree, standardization would be good.
It’s entirely up to the developers to collaborate and implement according to the spec though. ActivityPub wasn’t really designed with this use-case in mind, so the spec has limitations that warrant a specialized API, or extensions to the AP spec.
For example, the outbox is an OrderedCollection. This is how you would list posts in a magazine/community. However, there’s no way to sort by other metrics such as hot, top, or trending. Even Mastodon has its own REST API.
