I surveyed which public APIs are available on the Tohoku University Digital Archives (touda.tohoku.ac.jp/collection) and worked out a procedure to harvest metadata per setSpec via OAI-PMH and write each set into its own Excel file.
An implementation log for a digital archive that delivers historical photographs which cannot be made fully public, while still preserving the benefits of IIIF (spec-compliant high-resolution viewer, manifest delivery) for an authorized membership. The stack is Cantaloupe (IIIF server) + S3-compatible storage + Elasticsearch (search) + Next.js (UI) + Cloudflare Tunnel + Access. We also lay out where IIIF Auth API 2.0 would fit in for cross-host interoperability.
We applied two OCR engines — Japan's National Diet Library NDL Koten OCR-Lite and Cloud Vision API DOCUMENT_TEXT_DETECTION — to 105 IIIF images of fascicles 571–575 of the Mahāprajñāpāramitā Sūtra in the Jiaxing Tripitaka held by Yūrenja (formerly the Hōonzō of Zōjōji), and compared the patterns of error in their outputs. NDL produced phantom kana lines on 12 pages; Vision picked up color charts, rulers, and shelf labels as if they were body text on all 105.
