  Rossum is an AI-powered document processing platform specialised in
  transactional documents — invoices, purchase orders, contracts — with
  cognitive data capture, validation workflows and integration extensions.
  The Rossum REST API exposes organizations, users, workspaces, queues,
  schemas, annotations, documents and hooks/extensions across two deployment
  domains (legacy elis.rossum.ai and the newer per-tenant rossum.app).
