Function validate 

pub fn validate(graph: &StructuredDataGraph) -> ValidationResult

Validates a StructuredDataGraph against the Schema.org vocabulary.

Checks all nodes for:

• Unknown or deprecated types
• Unknown or misplaced properties
• Value type mismatches
• Deprecated/superseded properties

Examples

use schemaorg_rs::{extract_all, validation};

let html = r#"<script type="application/ld+json">{
  "@context": "https://schema.org",
  "@type": "Produc",
  "name": "Widget"
}</script>"#;

let graph = extract_all(html).unwrap();
let result = validation::validate(&graph);
assert!(result.has_errors());
