Everything behind these editions is one dataset: a typed, confidence-scored graph of where the New Testament quotes, alludes to, and echoes the Old. It’s released openly so it can be joined, queried, and built on — by a lectionary tool, a study Bible, a research project, or you. Generated from the editions on 2026-07-01 (commit 653daff).
Every echo as a typed, scored edge — one JSON object per line.
The inverted forward index: each source keyed to the New Testament places that reach for it.
Curated cases where the New Testament follows the Greek against the Hebrew.
Every chapter with a centrifugal trajectory reader (/fontium/read/[slug]), keyed by chapter-level refKey — the join for linking straight to a reader.
Field reference, the dual-key scheme, and method.

Two keys on every reference
Each record carries an OSIS refKey for machine joins and a human refDisplay for reading. Ranges are fully qualified at both ends, so an interval query resolves cleanly:
"source": { "refKey": "Isa.53.1-Isa.53.12",
"refDisplay": "Isaiah 53:1–12" }
// "what does the New Testament make of Isaiah 53?"
fontium.sources.filter(s =>
s.refKey?.startsWith("Isa.53"))Versification is KJV/WEB. The 32echoes pointing at pseudepigrapha (1 Enoch, Jubilees, 2 Baruch…) sit outside the OSIS core and are flagged extended. Full field reference in README.md.
