Turbo EA Business Architecture Reference Catalogue

The Turbo EA Reference Catalog is an open, MIT-licensed reference model for business architecture, covering three orthogonal artefacts — business capabilities (what the enterprise does), business processes (how it does it), and value streams (how value gets delivered end to end). It ships as YAML validated by JSON Schema, published as a JSON API and a Python package, and it is deliberately tool-agnostic: usable in LeanIX, Ardoq, Turbo EA, or a spreadsheet. It gives an architecture team a governed, machine-readable vocabulary for the demand side of the enterprise — the same vocabulary APIs should be mapped against.
