What feature of ArcGIS allows for collaborative editing among multiple users?

Versioning is a key feature in ArcGIS that facilitates collaborative editing among multiple users by allowing them to make changes to a dataset without interfering with each other's work. When versioning is enabled on a geodatabase, users can create their own versions of the data, which are essentially snapshots allowing them to edit and modify the data independently.

This system maintains a stable main version of the data while supporting multiple editable versions that can later be reconciled and posted back to the main version. As users are working within their own versions, they can make edits freely, and when they're ready to integrate their changes, they can reconcile their version with the main dataset, thereby allowing for conflict resolution and data integrity.

The collaborative aspect comes from the ability to manage and track changes made by different users, making it easier to coordinate edits and integrate them into the primary dataset effectively. This is particularly beneficial in team environments where multiple contributors may need to edit the same dataset simultaneously.

Other features, such as editing templates, shared geodatabases, and synchronization in ArcGIS Pro, support various editing processes but do not provide the same level of independent version control and collaborative capability that versioning does.
