When using Import/Export, what happens to existing metadata fields when you select the option to overlay metadata while importing a document load file that contains several blank metadata values?
A.
The existing values will remain in the corresponding mapped fields.
B.
The overlay will error for each document with blank values.
C.
The blank values will replace the existing field values.
D.
Only fixed-length text fields will be overlaid with the blank values.
The correct answer is C. The blank values will replace the existing field values. Relativity’s Import/Export document load file import documentation states that for Append/Overlay and Overlay Only , if a blank metadata field exists in the load file, the blank value will overlay remove any existing value in the corresponding mapped field. That means the blank value does not preserve the original value; it clears it.
This rules out the other options. The import does not preserve the old value in the mapped field, so option A is incorrect. The workflow does not error merely because blank values are present, so option B is also incorrect. Option D is wrong because the behavior is not limited to fixed-length text fields; it is described generally for mapped metadata fields in overlay mode. Therefore, the correct answer is that blank values replace existing field values during overlay import.
