I want to discuss the IIIF toolkit plugin.
I just installed the Omeka Classic, IIIF toolkit and Neatline plugins on our Linux server.
After then, I tried to import the first IIIF materials and the metadata.
But, I couldn’t import this material, https://www.iiif.ku-orcas.kansai-u.ac.jp/iiif/books/202278115/manifest.json, by any option, that is From File, From URL and From Paste.
I don’t know whether the error occurred by the IIIF Toolkit, my Omeka site or the json file.
