Overview
I created an app for viewing OCR results published on the National Diet Library’s “Next-Generation Digital Library” in an IIIF viewer.
You can try it at the following URL.
https://static.ldas.jp/ndl-ocr-iiif/
Usage
Enter the ID of a material published on the “Next-Generation Digital Library” in the input form.

After a short while, buttons for “Mirador” and CODH’s “Curation Viewer” will appear. You can view the OCR results in each viewer.

Display Example in Mirador

In particular, “Mirador” also supports the “IIIF Content Search API,” enabling in-material search.
