“Vṛścika lagna with Maṅgala in own sign — Ruchaka Yoga (BPHS 75.4). Drive and initiative are this native’s defining signature. Active Maṅgala mahādaśā through Aug 2026 — leadership, ambition, physical exertion peak here.”

04Anuvada — multilingual ontology

Seven languages. One ontology.

Anuvada is not a translation layer bolted on top. Every Vedic concept — yoga, dosha, nakṣatra, graha — is a JSON-LD entity with axes, grammar rules, and validated surfaces in all seven languages from compile time. Add a new language without touching the engine.

JSON-LD ontology

Every yoga, graha, rāśi, nakṣatra, and dosha is a structured entity with axes — quality, category, domain, timing, deity. Machine-readable definitions, not a word list.

Composition rules

Each language carries its own grammar templates and morphology rules. 'Gajakesari Yoga is active during Jupiter mahadasha' conjugates correctly in Hindi — not just transliterated.

SHACL validation

Shape constraints enforce completeness at build time. A concept with a missing Tamil surface fails the build — no silent gaps, no half-translated responses.

Extensible by design

Add a new language by contributing vocabulary, composition rules, and SHACL shapes. The engine picks it up automatically at the next snapshot compile.

58 yogas · all nakṣatras · 9 grahas · 12 bhāvas — ontology-complete in every language

Adding a new language means adding vocabulary, grammar templates, and SHACL shape files to the anuvada/ directory. The engine compiles it automatically — no code changes required.
