Hierologia: a machine-readable, source-attributed knowledge base for religious topics. Neutral, sourced, versioned.

Hierologia preserves theological, historical, and sociological knowledge across religious traditions as structured, neutral, well-sourced, and versioned data. This release covers the three Abrahamic traditions (Islamic theology/kalam, Christian theology, and Judaism), plus a philosophy namespace for the shared Greek substrate each tradition draws on, modeled as five entity types (concepts, figures, schools, events, and works such as the ecumenical councils and creeds, the Abbasid Mihna, and the hadith collections) linked into a graph. Each entry is sourced and peer-reviewed, and cross-tradition links compare comparable questions across traditions without equating their answers. It is compiled with AI assistance under human editorial oversight; its sources are independently verified and most entries are peer-reviewed rather than expert-verified (see the repository's methodology).
