Probing the Public APIs of the Tohoku University Digital Archives — Exporting per-setSpec Excel via OAI-PMH

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.

Building an Access-Controlled IIIF Digital Archive — Cantaloupe + S3 + Elasticsearch + Next.js, Gated by Cloudflare Access

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.
