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
`workspace`	High-level `Workspace::open` API — incremental index, diff, import graph
`diff`	Semantic catalog diff, version refs, breaking-change heuristics
`catalog`	Index builder and entity catalog
`query`	SQL virtual tables and SPARQL
`diagnostics`	Lint rule collection
`parser`	RDF/OBO parsing
`owl`	Horned-OWL bridge, patches, Manchester
`reasoner`	Ontologos classification facade
`refactor`	Workspace refactoring
`docs`	Markdown/HTML documentation export
`lsp`	LSP protocol types (feature `lsp`, enabled by default in docs.rs via `all-features`)

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

Features

Feature	Description
`lsp`	Re-export `ontocore_lsp::protocol` and `catalog_snapshot_json`
`plugins`	Plugin manifest discovery via `ontocore::plugin` (v0.14 foundation)

Default features are empty — enable lsp when you need LSP wire types:

ontocore = { version = "0.13", features = ["lsp"] }

Binaries

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