ontocore

OntoCore is the public façade API for the semantic workspace engine.

This crate re-exports the stable surface of OntoCore for Rust applications. Implementation lives in the ontocore-* crates (ontocore-core, ontocore-catalog, ontocore-query, etc.) — use those directly when you need lower-level control.

Quick start

use ontocore::Workspace;

let workspace = Workspace::open(".")?;
let diagnostics = workspace.diagnostics();

let result = workspace.query("SELECT short_name, labels FROM classes")?;
for row in &result.rows {
    println!("{:?}", row);
}

Modules

Module	Role

Ecosystem

Component	Role
OntoCore (`ontocore`, `ontocore-*`)	Semantic workspace engine — this crate
OntoLogos	Reasoning engine (classification, consistency, explanations)
OntoCode	VS Code IDE powered by OntoCore
External plugins (e.g. owlmake)	Workflow/build/release automation — integrate via OntoCore plugin APIs, not core dependencies

Binaries

CLI: ontocore (ontocore-cli crate) — cargo install ontocore-cli --locked
LSP: ontocore-lsp — bundled in the OntoCode VS Code extension
