Written by hand from Part IV, 1.1.1 and 1.1.2, not generated: tools/generate-schemas.mjs keeps this folder and lists none of it in index.json. No file of OpenEik 0.1 is held to it. @openeik/tools holds to bodies.schema.json the results an application hands its IFC bridge, and writes its own derived layer in it.",

  "description": "The index of the proposal derived (Part IV, 1.1.1 and 1.1.2, proposed for 0.2). It is a schema that asserts nothing: its member x-eik-proposal maps each result of the derived layer to its schema, by its path in a folder, an element's at .eik/derived/elements/<id>.json and a type's at .eik/derived/types/<id>.json, each id written as a path segment (Part III, 2), and by its key where results are handed from one tool to another, elements/<id> and types/<id>. A result is never in a version (Part IV, 1.1, rule 3). Schema paths are relative to https://openeik.org/schemas/0.1/.",
