We are planning to utilize, AEM 6.4 metadata download and update using CSV file.

But we have observe that it does not delete the asset's metadata value if column value is blank in CSV against a property.

Steps to repro are -

1. Download the metadata csv file.
2. Open file and delete a value in csv.
3. Upload it using create > metadata option in dam.
4. Go back in crxde or dam properties to check if value is removed for property against which value was blank in csv.

Kindly share if any workaround. Its one of requirement we have to implement.

Sujeet
