Thanks to Maria for pointing me in the right direction. I suspect the problem is my inexperience! I’m using a modification of the simple teaching edition script to import files and metadata from a csv file. (a modified BibTex file from Zotero) My modified script is pictured in this screenshot.
It works wonderfully! The keywords, however, imported as strings and don’t function as I would like them to–as tags do in the Generic meta-data field.
I suspect that importing the keywords as “strings” may be the problem; they are more like a list. I would like the keywords to function as tags, so that I can filter with them. Any ideas are most welcome!
