Thank you, that is helpful.
I’m having a research assistant create notes (in markdown txt files) on a series of academic papers.
I’d like a way for the RA to insert, in the note file, the date that the original paper was published, in such a way that I can sort the notes chronologically in DT by those dates. So I created a custom metadata field for the original publication dates but it sounds like there’s no way for DT to figure out what should go in that field from the contents of the file itself.
The notes are in a folder that’s indexed to DT, but the RA does not have access to DT, just the files. I haven’t sprung for server edition yet, but maybe that is the answer.
