I'd like to update my metadata outside of SoundMiner, but I don't know what format it accepts. Is it XML, CSV or something else?
In short: What format does SoundMiner accept to import metadata from?
This page indicates that the format is a plain text (.txt) file: http://www.creativefieldrecording.com/2014/06/24/the-power-users-guide-to-soundminer-metadata/
The following excerpt from that page hints that they're formatted as tab-delimited text.
"Ensure there’s a “tab character” between the data in each column. This keeps the data in one column from becoming confused with its brothers on either side."
