[#1]

Request for Feature Enhancement (RFE) Summary:	Export / Import Metadata
Use-case:	Contributors need to export assets metadata which are on the jcr:content node like onTime or offTime, then modify these values and update them massively in the dam
Current/Experienced Behavior:	Contributors cannot select offTime or onTime property on the export metadata interface /mnt/overlay/dam/gui/content/metadataexport.html?payload=/content/dam/nicephore/animations/nouvel_an_lunaire&_charset_=utf8 On the import interface /mnt/overlay/dam/gui/content/metadataimport.html the columns offTime{{Date}} and onTime{{Date}} are ignored
Improved/Expected Behavior:	All metadata can be exported and imported, no matter if they are on the /jcr:content or /jcr:content/metadata node
