  title: Amazon Lake Formation Register Resource and Grant Permissions
  summary: Register an Amazon S3 location as a data lake resource and grant a principal access to it.
  description: >-
    The foundational Lake Formation onboarding flow. The workflow registers an
    Amazon S3 path as a Lake Formation managed location using a data access IAM
    role, confirms the registration by describing the resource, grants a
    principal a set of permissions on a Data Catalog resource, and finally lists
    the resulting permissions so the grant can be verified. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
