Crate jnana 

Jnana — the foundation of knowing

Jnana (Sanskrit: ज्ञान — knowledge, wisdom) is the unified knowledge system for AGNOS. It distills human understanding into structured, tested, queryable, offline-accessible data — drawing from AGNOS science crates and curated external sources.

Philosophy

Wikipedia is 50GB of prose. Jnana is 1-10GB of proven, testable, executable knowledge. Every formula is verified by a test. Every constant comes from an authoritative source. Every procedure works.

Knowledge Sources

Internal (from AGNOS crates — distilled, tested):

• hisab: math formulas, linear algebra, calculus, geometry
• kimiya: periodic table, reactions, thermochemistry
• tanmatra: particle physics, nuclear data, spectral lines
• prakash: optics tables, spectral data, Fresnel equations
• pramana: probability distributions, statistical methods
• bodh: cognitive models, psychophysics laws
• vidya: programming best practices across languages
• …every science crate’s reference data

External (curated, downloaded, verified):

• Medical references (WikiMed, field medicine guides)
• Survival procedures (shelter, water, food, navigation)
• Repair guides (iFixit, practical how-to)
• Agricultural science (FAO, permaculture, aquaponics)
• Construction (earthbag, timber, solar, plumbing)

Modules

• domain — Knowledge domains and their entries
• entry — Core types: Entry, Fact, Procedure, Constant, Table
• registry — In-memory knowledge registry with lookup and search
• profile — Storage profiles (survival, homesteader, developer, educator, full)
• search — Cross-domain search
• source — External source management (download, verify, update)
• portal — Web portal generation from registry
• storage — Budget calculator, what-fits analysis
• error — Error types

Example

use jnana::{Registry, SearchQuery};

let registry = Registry::new();
if let Some(entry) = registry.get("speed_of_light") {
    println!("{}: {}", entry.title, entry.summary);
}
let results = jnana::search::search(&registry, &SearchQuery::text("binding energy"));
