Social graph

Querying social graphs

New applications that build on the AT Protocol can leverage existing social graph data — for example, from the app.bsky.graph.getFollows Lexicon RPC endpoint — to build new use cases, and bootstrap with an existing user base. This, in turn, gets you to native ATProtocol concepts like A Social Filesystem.

See Exploring AT Protocol with Python for another example of this approach.

Backlinks

One of the most powerful ways to get social graph data from AT Protocol is through the use of backlinks. Querying backlinks lets you resolve all of the records linking to any given record, or identity.

Microcosm provides a set of resources for working with backlinks. Because all AT Protocol records are openly available and addressible via an at:// URI, this makes it possible to encode nested API queries into individual URLs. Microcosm does this, for example.
