REST/HTTP is used for one-off resource fetches; the WebSocket protocol (atomicdata-ws) is the primary channel for real-time sync and subscriptions.
-
All Atomic Data resources have a unique URL, which can be fetched using HTTP.

Released 2020-08
Corrected from 2020-09. The project's own roadmap page dates AtomicServer's first appearance to August 2020, matching the first crates.io publish (2020-08-10); the GitHub repository's July 2020 creation date reflects only the initial commit, not a public release.
-
AtomicServer (2020-08). The server (using the same atomic_lib as the CLI) should be a fast, lightweight server that must be easy to set-up. Functions as a graph database with no dependencies.
