I've been exploring permissioned data spaces technology and components, thinking about what the end-result is going to look like. @dholms.at's last dev diary has some good nuggets and I decided to jump into an ECMH implementation.

Permissioned data by dholms · Pull Request #94 · bluesky-social/proposals
This is an initial proposal for permissioned data. Details, terminology, and behaviors are all likely to change. For a friendly introduction to the protocol, check my my Leaflets. For discussion, f...
Permissioned data proposal discussion
This is a forum thread to collect feedback on the permissioned data protocol proposal! To clarify: this is still a proposal. I expect many changes along the way. Suggestions may also be submitted as issues/PRs. I had hoped to have an alpha version of the PDS alongside this proposal, however I didn’t quite get there yet. Hoping to have that in the next couple weeks. The previous thread was here: Early permissioned data proposal draft feedback Changes since then: Responded to a bunch of feed...
Permissioned Data Diary 2: Buckets - Daniel's Leaflets
The second in a series of posts building up a solution to permissioned data on atproto. We introduce buckets: a new protocol primitive for creating a shared social context.
Permissioned Data Diary 3: Your Bucket, My Data - Daniel's Leaflets
The third in a series of posts building up a solution to permissioned data on atproto. We look at two different models for where buckets live and why the simpler-looking one doesn’t work out.
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.
Permissioned Data Diary 1: To Encrypt or Not to Encrypt - Daniel's Leaflets
The first in a series of posts about major design decisions along the way to a permissioned data protocol for atproto.
Permissioned Data Diary 5: What’s in a Name? - Daniel's Leaflets
In this permissioned data diary, we dive deep into the URI structure for permissioned data on atproto and use it to motivate a bunch of the larger design.
Permissioned Data Diary 5: What’s in a Name? - Daniel's Leaflets
In this permissioned data diary, we dive deep into the URI structure for permissioned data on atproto and use it to motivate a bunch of the larger design.
@dholms.at thinking about permissiones data. What if: Permissioned data URI was at://<PDS did>/<record type>/<rkey> exactly the same as public data. The PDS would handle the space assignment opaquely and do a 4xx response with some space aturis. Client goes and grabs a space cred and retries
Me and @zicklag.dev have been having a closer look at the system sketched out in @dholms.at's Permissioned Data Diaries - we generally like it! And have some scenarios in mind that may be worth considering

meri.leaflet.pubhere it is folks! lots of details to still nail down, but this is roughly where our heads are at for the design of a permissioned data protocol give it a read and let me know your thoughts!

Permissioned Data Diary 4: The Big Picture
dholms.leaflet.pubcontinuing to build up our permissioned data protocol! this one asks what a bucket actually is and where the data that constitutes a bucket is stored. it argues for maintaining the atproto ethos in the permissioned data protocol as always, looking forward to hearing your thoughts!
