How to use this family

• consumable: set type to a type code below and send its properties in details.
• consumableapproval: type selects the type; each log entry added through the entry actions is validated against it.
• Every version is published at https://www.brainstem.org/schemas/Consumable/<Type>/<version>.json and never changes; https://www.brainstem.org/schemas/Consumable/<Type>.json is the current version and https://www.brainstem.org/schemas/Consumable/<Type>/ lists the versions. See Public schemas.
• Quantities are objects {"value": <number>, "unit": "<code>"}. Property paths with [] are inside a repeatable list of rows. The server sets the schema version field itself.
