Objects

Edit objects in bulk

The same change on all objects in the current selection, for example moving the loan start of all loans in an exhibition by one week, or correcting a loan list in one go.

Film: batch with preview and undo
  1. Narrow down the selection. The batch covers exactly the objects the view has loaded. Filters, full-text search and the Wahl filter are the tools for this. The number in the footer is the number of objects affected. Reading it is the first safety step.

  2. In the workspace, open the Batch tab. It contains the Batch editor.

  3. Add card. Choose a field, then the channel: Value, Colour, Source or Comment.

  4. Choose the kind of change. You are offered what suits the field: text tools, arithmetic, date tools or toggles. Each kind comes with a sentence explaining it. For the Colour channel there are only Replace and Clear.

  5. Check the preview. For each object, the old and new value, with the differences highlighted. You can deselect individual objects. Hide unchanged shows only what will actually be written.

  6. Apply. Per card with Apply changes in this field, or all together with Apply all changes for all fields.

The pending changes dialog in the Batch tab of Sonderausstellung 2026 with a card for Leihbeginn (loan start) in the mode Shift by days and the value 7, below it the preview with the current and new date for each object.

Still: card for Leihbeginn in the mode Shift by days with 7 days, preview of old and new, at the top the button Apply changes in this field.

Mind the save scope

If the objects are in several projects, one Save scope applies to the whole run:

ScopeWhen
Hybrid (auto)The normal case. Fields with a project-specific value write that value, all others write the shared value
Current ProjectWhen the change should affect only this project, such as the catalogue numbers of an exhibition
Base ObjectWhen you explicitly want to change the shared value

See Project-specific values .

Moving objects to the trash is quicker through the object menu, see Delete an object .

If something goes wrong

A batch run can be undone as a whole: in the sidebar, open the Editing History tab, view Batch operations, and click Undo Batch next to the run.

The dialog marks conflicts: fields that have been edited again since. The usual approach: select the entries without a conflict and undo them, then look at the conflicts individually.

See Trace changes .
