§ 3Backward compatibility
A core design principle: any document using jsonld-ex extensions remains valid JSON-LD 1.1 once the extension keywords are stripped. Standard tooling that doesn't know about
@confidence or @vector still parses the document correctly.Input
extended document
Output
stripped — pure json-ld 1.1
