How to batch import IIIF items

Dears,
We encountered challenge to import hundreds of IIIF items, exactly as in below post, which they manual imported those items at the end of the day. Sad story… :disappointed_relieved:

Since it was a story happened in 2016, I was wondering is there any new plugins that came up since then that can help dealing this situation?

I tried plugin of “Batch Upload”, released in 2018. It allowed me to map IIIF item metadata such as “@id” and Json Data, and the status said it was successfully imported, only the item didn’t show up in viewer, so I guess the IIIF item wasn’t imported correctly.

Any idea?
