The briefcase has not been assigned a unique Id by iModelHub. Only briefcases that have been assigned a unique BriefcaseId may create changesets,
because BriefcaseId is used to create unique ElementIds for new elements.
The Unassigned briefcaseId is used for several purposes:
- Snapshots. Snapshot files are immutable copies of an iModel for archival or data exchange purposes. They can neither generate nor accept new changesets.
- Checkpoints. Checkpoints are Snapshots that represent a specific version on an iModel's timeline.
- PullOnly. A local briefcase file that may be used to "slide" along a timeline by applying incoming changesets.
They are always opened readonly except to apply changesets.
- Standalone. Standalone iModels are local files that are not connected to iModelHub, and therefore cannot accept or create changesets. |
