  Entity graph derived from the Autonomous AP Swagger 2.0 resource paths and
  their id-reference fields. Master-data entities (suppliers, entities, chart
  of accounts, tax, vat, payment terms, units of measure, lookups) are
  referenced by transactional documents (invoices, purchase orders, goods
  receipts). Every entity is addressable by a global uuid plus an external id.
