🪣Rewriting JSONkeeper on Cloudflare Workers + D1 — A 360-Line Hono + jose Replacement for the IIIF Curation Viewer's Save Backend

A from-scratch rewrite of JSONkeeper — the save backend for the IIIF Curation Viewer — not on top of the original Flask code, but as a Cloudflare Workers + D1 service. Covers Firebase ID-token verification with Hono + jose (no Admin SDK, no service-account key needed), the D1 SQLite schema, top-level + nested JSON-LD `@id` rewriting, a minimal Activity Stream collection, CORS and Viewer-compatible headers, a wrangler-based deployment runbook, and a feature-by-feature diff against upstream JSONkeeper.

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.

Routing an Externally Managed Subdomain to Cloudflare Workers — Adding AWS CloudFront + WAF as a Front Layer

An attempt to assign a subdomain managed by an external organization's DNS as a Cloudflare Workers custom domain hit the constraint that Cloudflare's free plan doesn't accept external subdomains as zones. The final solution was to place AWS CloudFront + WAF in front as a termination layer.
