Rust & CLI (OntoIndex)

OntoIndex is the Rust engine behind OntoCode: the ontoindex CLI, published ontoindex-* crates on crates.io, and the ontoindex-lsp language server (also bundled inside the VS Code extension).

Looking for the VS Code extension only? See the VS Code extension path.

Quick start

cargo install ontoindex-cli --locked
ontoindex query /path/to/ontologies "SELECT * FROM classes"
ontoindex validate /path/to/ontologies

No clone required. Release binaries: release integrity.

CLI getting started — install options, first commands, fixtures.
