+# Open Christian Data
+
+Public domain Christian literature as structured, machine-readable data — for developers and AI training.
+
+Commentary data is trapped in HTML and PDFs. No structured commentary dataset exists on HuggingFace. No per-chapter commentary JSON exists on GitHub.
+
+This dataset processes public domain Christian literature — commentaries, church fathers, confessions, catechisms, devotionals, prayers, sermons — into clean, schema-validated records with full provenance metadata.
+
+**GitHub:** [OpenChristianData/open-christian-data](https://github.com/OpenChristianData/open-christian-data)
+
+## Schema types

+| **Total** | **247,649** | |
+
+## Data format
+
+Every record is a flat JSON object. Six fields are inlined from the source file's metadata:
+
+| Field | Description |
+|---|---|
+| `_source_id` | Unique identifier for the source work |
+| `_source_title` | Title of the source work |
+| `_author` | Author name |
+| `_schema_type` | Schema type (matches the config name) |
+| `_license` | License identifier (`cc0-1.0` or `public-domain`) |
+| `_source_url` | Canonical URL for the source |
+
+The remaining fields are schema-specific. All verse references use OSIS format (`Gen.1.1`, `Rom.9.1-Rom.9.5`).
+
