Lexicon Embeds Overview
ATProto’s inside out structure provides an opportunity for open, permissionless building on top of any component in the network, including its extensible data schema definition system, Lexicons. One of the opportunities this presents is users sharing their data and records with multiple apps. Those apps may be direct substitutions (different clients for microblogging say), or apps that use that data in a variety of ways, such as Popfeed an app which aggregates posts about a variety of media ty...
How do we talk about atproto to non-developers?
The beauty of AT Protocol is that all of your data from different apps is available on your PDS, your own folder on the internet containing your stuff as JSON. This means that you can switch which app you use to view that data, without losing anything. It also makes it very easy to make connections between data stored using different lexicons, or just display activity in one place. Sifa does a nice job of this on your profile page. For web developers, and people who understand webhosting, the concept is reasonably easy to understand. I know that any atproto app I join is going to store data in my PDS, any other people will be able to see it.
What is atproto?
What is atproto? atproto is two things: A protocol for creating open social networks An open social network atproto, the open social network Today the atproto network has 36+ million users and powers Bluesky and a handful of other apps. Almost all atproto data is public. Content like posts, likes, follows, and photos/videos are publicly accessible to any network participant in a permissionless way. As an example of how open the network is, here’s how easy it is to stream all public data on the network using a public atproto Relay like bsky.network:

Oh this is interesting. At first I thought it was yet another lexicon to wrap data on, but it's a way for anyone to use ATProto as a discovery mechanism for their non-PDS-hosted datasets. I hadn't thought of the ATmosphere and the relays as a way to surface arbitrary existing data until know.

🪩 Introducing matadisco.org! — a way to discover open datasets via #atproto that doesn't depend on any single institution staying online. 🕺🏼 We have more public data than ever (satellite imagery, climate models, genomic sequences), but finding it is still painfully hard.
Imagining atproto as a post-app protocol starts with materializing the social filesystem – decomposing apps and their data into materials and instruments. For the time being, this guestbook is a good example where the display element is a material and the sign element is an instrument.

in any case, the end game is composing these little guys, whatever goes on behind the scenes. social components
I suspect we’ll see a bunch of apps that leverage atproto’s did:plc identity layer but store data out of band.

Atproto Is the Context Window You Own - The Tropopause
pckt.blogthe critical thing that got me on board with atproto is relays incrementalize sync of the entire dataset, which eliminates polling when crawling the old web is currently being crushed under crawler load and I don't think it's going away, so I think atproto is the only way to save the open web
This is partly why I think atproto needs a more convincing vision about being a post-app protocol. A future where atproto is a bunch of apps and each app governs their own lexicon diminishes a lot of its potential in the long-term.

yeah i think i might actually, theres a very interesting story here that the main thing that matters is a focal point around which consensus over a lexicon can get formed
