The Capital Layer · Ontology

The QIS knowledge graph.

Every reference document in this ecosystem is a node. Every concept it addresses is a node. The edges between them are the argument: what a strategy family depends on, which definitions a governance standard rests on, which infrastructure a workflow actually runs on. This is that structure, rendered directly and published as open data.

The diagram is a convenience. The authoritative index is the text below, and the authoritative data is /api/graph.json — a stable, CORS-enabled JSON document you are free to fetch, cache, mirror, and cite. If you build something with it, tell us and we will link to you.

The Index

Every document, by layer.

The same graph as a plain list, because a list is what a crawler, a screen reader, and a person in a hurry actually need.

The Vocabulary

The concepts that connect them.

Each concept below is an edge type in the graph — the reason two documents are related rather than merely adjacent. Definitions for the terms of art live in the glossary.

Open Data

The ontology is the product.

Three JSON documents are published at stable URLs, served with permissive CORS headers and long cache lifetimes. They are versioned, they will not move, and they are meant to be consumed by other people's software:

  • /api/graph.json — the full node and edge set behind this page.
  • /api/pages.json — every canonical URL across the three domains, with titles, descriptions, layers, and topics.
  • /api/glossary.json — the canonical QIS definitions as structured terms.

All three are also described in llms.txt and llms-full.txt for retrieval systems. Attribution to the source URL is the only thing asked in return.
