[digilib-devel] IIIF Image API 2.0 info.json error and patch

[Yury E. <yur...@gm...>]

Hi All!

We're trying to use digilib with Mirador project and encountered an error
in info.json generated by digilib:

{
  "@context": "http://iiif.io/api/image/2/context.json",
  "@id": "http://localhost/Scaler/IIIF/1012626",
  "@protocol": "http://iiif.io/api/image",
  "width": 750,
  "height": 586,
  "profile": [
    "http://iiif.io/api/image/2/level2.json",
    {
      "formats": [
        "jpg",
        "png"
      ],
      "qualities": [
        "color",
        "gray"
      ],
      "supports": [
        "mirroring",
        "rotationArbitrary",
        "sizeAboveFull"
      ]
    }
  ]
}

According to IIIF Image API 'protocol' parameter should go without '@'

http://iiif.io/api/image/2.0/#image-information

incorrect: "@protocol": "http://iiif.io/api/image"

correct: "protocol": "http://iiif.io/api/image"

This issue could be patched with this:

It would be nice if it's fixed soon.
