Tropy 1.18.0-beta.1's project files (.tpy / .tropy) are SQLite databases, and the desktop app embeds an HTTP API. A walk-through of driving both from Node scripts, the side findings, and the PR / issue we sent upstream.
Taking the first folio of Cing gisun-i Lao Kida (volume 1, fol. 1a) — a Joseon-era Manchu language primer — I encoded the page in TEI/XML using only standard elements and reproduced its vertical layout (Manchu script + Hangul phonetic gloss + warigaki Korean translation) with XSLT 1.0 generating HTML + SVG. This post records the design decision to separate data from visualization, the column-splitting trick in XSLT 1.0, the SVG-based rendering of Manchu script, and the three-panel comparison view (facsimile / XML / HTML).
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.
