A new policy-based arbiter prototype and a draft of an interoperable lexicon for group servers.
Arbiter Progress Report 4 - Zicklag's Leaflets
In which we abuse permission sets to create virtual custom scopes for the arbiter.
Arbiter Progress Report 1 - Zicklag's Leaflets
Lots of implementation progress & lots of discussion with the community.
The Arbiter - Group Management for Permissioned Spaces and Beyond - Zicklag's Leaflets
The permissioned data proposal has the concept of membership, but leaves it to the app to orchestrate it. The arbiter is our idea for a general-purpose, interoperable ATProto group membership service.

Arbiter Simulator
Interactive simulator for the Arbiter authorization system — design and test auth structures in the browser.
I have just finished an interactive arbiter simulator that runs right in the browser! The arbiter is our attempt at an interoperable group management system for the ATProtocol and permissioned spaces. zicklag.github.io/leaf-0.4/arbiter-simulator/
I just finished a progress report / summary of the arbiter server that we've been working on at @roomy.space. The goal is to have an interoperable standard for group membership management on top of the ATProto permissioned space proposal. The last couple weeks were full of progress & discussion!
Arbiter Progress Report 1 - Zicklag's Leaflets
zicklag.leaflet.pubAt @roomy.space we've been cooking up the design for the next, ATProto-native iteration of Roomy, and that includes private data on protocol! The first component that we're working on is a group membership service that we're calling the "arbiter". Here's full overview of the design so far!
The Arbiter - Group Management for Permissioned Spaces and Beyond
zicklag.leaflet.pubAnother arbiter progress report! An attempt at a goups standard for ATProto. This week we talked to @habitat.network and it got us thinking about how we could inter-op, even with other projects that can't use the arbiter. Now we've got a draft lexicon that I'm hoping can work for both of us.
Arbiter Progress Report 2 - Zicklag's Leaflets
zicklag.leaflet.pubI've just finished the first, barely-working prototype of our new arbiter server! It's not ready for use just yet, but we're going to start experimenting with it in @roomy.space as a way to make every space a fully-fledged ATProto account that can be seamlessly managed by the Roomy space's admins.
