  title: Bentley Start an iModel Authoring Session
  summary: Acquire a briefcase, take element locks, and push a changeset to author an iModel.
  description: >-
    Authoring an iModel requires a briefcase — a local checkout identity — and
    element-level locks so concurrent editors do not collide. This workflow
    acquires a briefcase, takes the requested locks against that briefcase, and
    then creates a changeset that records the edits made during the session.
    Each step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
