@tom yeah, activitypds is the research project name, but there's a bunch of upstream work in Fedify to enable C2S in Fedify, and then also to enable reusing the Fedify vocabularies (they take JSON-LD and convert into classes that Fedify understands, and handles serialisation to JSON-LD)

@tom basically the things I'm trying to solve in ActivityPDS are:
- an OAuth profile (based on AT Proto's OAuth profile)
- webfinger & DIDs & Handles
- what should a "PDS" do in the context of ActivityPub C2S, how much logic does it implement, or is it just a simple pipe?

@evan oh yeah this should be perfect

@tom I can also send you an invite code.

There's a chapter on the social API in the ActivityPub book.

ActivityPub book

In September 2023, I started work on a book about ActivityPub for O'Reilly Media. As of September 2024, the book is now available! Ebook The book is available from several different ebook vendors in different formats. O'Reilly Learning Platform Amazon Apple Books ebooks.com Kobo Print The book is not yet available in print format. O'Reilly…

@box464 @tom awesome! Make sure to add issues or PRs as you come up with ideas.

@tom there's a discussion here

Which ActivityPub applications support Client-to-Server (C2S)?

@evan I signed up to get notified for the print edition a few months ago, still prefer actually holding physical books haha

@tom OK!

@tom I basically follow actors and that's how seeing posts by others in your /inbox works.

The frontend loads stuff directly through JavaScript fetch and needs all the mechanisms of that to work (and I imagine what you see might be things failing to load due to CORS rules being too restrictive on remote Mastodon instances)

I am not aware of any issues with receiving activities though, and in this process the objects themselves should be fully dereferenced to local copies.

I'll add a note about BOX compilation. Thanx.

@tom looking at the post of mine you linked, I realize you're probably thinking of regular object discovery, and there isn't any mechanism for it yet, or for viewing remote objects that haven't reached your inbox.

@julian yes, two of them:

https://rattlehead.bruta.link < where a bot posts daily metal releases scraped from the internet

https://marius.federated.id < where I write a bit about stuff and play with more expressive ActivityPub objects.

@mariusor sorry I meant the reverse behavior, viewing Oni users/activities from my mastodon instance (or from mastodon.social) not viewing remote activities from oni

I.e. searching for https://marius.federated.id/outbox/1725894299052/object doesn't pull up the object in mastodon (and searching for the user doesn't bring that up either)

@tom I understand.

Indeed in the past two/three weeks I must have deployed something (or Mastodon made some changes) that regular objects posted by ONI aren't findable any more. The problem is that I don't have a development setup for mastodon on which to test what the problem is.

However the actors should still be available.
