Strixonomy SQL views¶

Strixonomy exposes ontology data as SQL virtual tables over the indexed catalog. Queries run locally — no database server required.

Quick example¶

strixonomy query ./ontology "SELECT short_name, labels FROM classes"

use strixonomy::workspace::Workspace;

let ws = Workspace::open("./ontology")?;
let result = ws.query("SELECT short_name FROM classes WHERE deprecated = 'false'")?;

Boolean columns use string literals ('true' / 'false'). Full subset rules: SQL reference.
