Thank you for this, @mhucka!
Would it be possible to add an option to skip files with a value written? I try to run zowie on my Zotero folder, but it never finishes. Every time I get the error below at some point and when I try to run it another time, it always starts back from the beginning. I would like to skip those files that already have a value to allow zowie to work on those that were not yet processed.
Encountered error HTTPError:
Code: 502
URL: https://api.zotero.org/groups/.../items/...?format=json&limit=100
Method: GET
Response: <html>
<head><title>502 Bad Gateway</title></head>
<body>
<center><h1>502 Bad Gateway</h1></center>
</body>
</html>
It would also be very interesting if zowie could also pull the value from other Zotero fields (citekey, title, author) and write them to the file’s metadata attributes. Just an idea
