Object history traceability is different from the historical moment function. Object history traceability targets objects, while historical moments target the entire dataset. Object history traceability includes two functions: object history changes and historical deletions. Object history changes refer to the historical trace of the current object edits, with historical data stored in the object properties. Historical deletions refer to the historical trace of deleted objects, with historical data stored in the dataset properties.
Historical Change
When an object in a versioned datasource changes, the change time will be recorded in the object's attributes. The history of changes is described as follows:
When an object in a versioned Dataset changes, the time of the change is recorded in the Object Properties. The operation of Historical Change is described below:
- Select the edited object in the map window, right-click to choose the properties option, and you can view the change history in the Historical Change section of the object properties panel. The change history list includes historical timestamps and user information.
- Click on any of the historical records, and the object’s spatial location at that time will be displayed in gray in the map window.
- If it is Property Change, you can view the property change by selecting the Attribute Comparison item of the record with the right key.
- If a record in Historical Change is the correct information, you can restore the Data Information of the Historical Moment through the Recover Object button in the HistoryContext Menu.
Caution: After Recover Object, you need to manually delete the object before recovery and keep only the object after recovery.
Delete History
The objects deleted by mistake can be retrieved from the Delete History. The specific operations are as follows:
- In Workspace Manager, select the Properties item in the DatasetContext Menu to open the Dataset attribute panel. All Objects deleted in the Dataset are recorded in the Delete History of the panel, including Object ID, Delete Moment, and User Info.
- Search the wrong Delete Object record through Object ID or Delete Moment. After the record is selected, the spatial position of the object at that moment will be displayed in gray in Map.
- After finding the mistakenly deleted object record, select the Recover Object button through the Context Menu to retrieve the mistakenly deleted object.
