  Derived from the documented DS3 S3-compatible object model (buckets, objects,
  versions, tags, object-lock, access keys) at https://docs.cubbit.io.
description: >-
  Entity-relationship model of the Cubbit DS3 platform, derived from the S3
  object model DS3 implements plus the console concepts (project, access key).
  DS3 has no published OpenAPI, so relationships are derived from the documented
  resource hierarchy rather than $ref graphs.
