Controlling Change History

Record Triple Counts only

Record Triple Counts only is available under the Manage tab. It disables recording change history at the level of individual triples for production copies. When activated, EDG only records summary counts of changed triples – added or deleted. This significantly reduces storage and memory impacts at the cost of losing detailed change information and the ability to undo (revert) the changes.

Working copies and existing change history are not affected by this setting.

Archive Working Copies(Workflows) on Commit

Archive Working Copies on Commit is available under the Manage tab. When true, working copies are archived automatically when a workflow is committed.

Note

The archive always contains the full history, regardless of the Record Triple Counts only setting.

Changes made in the archived working copies will not show up in the Change History after commit. Archived workflows continue to be listed in the Completed Workflows table on the Workflow tab.

The archives are stored in a special “archive” folder on the server. System Administrators can move or permanently delete the archived data so that it isn’t using up storage space when not needed.

Clear Change History

Clear Change History is available under the Manage tab. It removes the audit trail from the collection, meaning users can no longer revert a change using the editor form.

Over time, the change history about a collection can become very large adding to the workspace/database causing more memory to be used by EDG. In order to improve performance, users may want to periodically clear change history if it is not being used.

Note

This operation is not reversible. To recover cleared content, use backups.
