Overview

HTTP access to a bundle's knowledge graph — a Rack app, so it runs under any Rack server (WEBrick, via okf server) and can be mounted in a Rails app:

mount OKF::Server::App.new(folder) => "/knowledge"

The page (OKF::Server::Graph) boots from a minimal graph (id + title + edges

  • type/tag indexes) and pulls each concept's markdown body and description from here on demand, so the initial payload stays small and bodies are read live from disk (edits show without a restart). Part of the shell — it does I/O.

    GET / the interactive graph page (text/html) GET /node?id=… the concept's raw markdown body (text/markdown) GET /node/meta?id=… its description, as an escaped HTML fragment GET /catalog rich per-concept metadata for the catalog/files/stats views: { concepts: [ title, type, description, tags, timestamp, status, area, dir, links_* ] } (JSON) GET /tags the tag index { tag => [id, …] } (JSON) GET /types the type index { type => [id, …] } (JSON)
