1//! # OxiRS WASM
2//!
3//! WebAssembly bindings for OxiRS - Run RDF/SPARQL in the browser.
4//!
5//! ## Features
6//!
7//! - **RDF Parsing**: Turtle, N-Triples, JSON-LD
8//! - **In-Memory Store**: HashMap-based triple store
9//! - **SPARQL Queries**: SELECT, ASK, CONSTRUCT
10//! - **Validation**: Basic SHACL validation
11//!
12//! ## Example (JavaScript)
13//!
14//! ```javascript
15//! import init, { OxiRSStore } from 'oxirs-wasm';
16//!
17//! await init();
18//!
19//! const store = new OxiRSStore();
20//! await store.loadTurtle(`
21//!     @prefix : <http://example.org/> .
22//!     :alice :knows :bob .
23//!     :bob :name "Bob" .
24//! `);
25//!
26//! const results = store.query('SELECT ?name WHERE { ?person :name ?name }');
27//! console.log(results);
28//! ```
