public class JsonLdParser extends RdfParser
Subclass of RdfParser for parsing JSON-LD into POJOs.

Accepts RDF in W3C JSON-LD format and converts it to Java beans, maps, collections, and primitive types. Date/time literals are parsed via ISO 8601.

Examples:

// Parse JSON-LD string into a bean. String jsonLd = ...; // JSON-LD content Person person = JsonLdParser.DEFAULT.read(jsonLd, Person.class);

// Or use the JsonLd marshaller for convenience. Person person = JsonLd.DEFAULT.read(jsonLd, Person.class);

// Parse into a list of beans. List<Person> people = JsonLdParser.DEFAULT.read(jsonLd, List.class, Person.class);

// Custom parser with swaps. JsonLdParser p = JsonLdParser.create().swaps(DateSwap.class).build(); MyBean bean = p.read(jsonLd, MyBean.class);

Example input (bean with name/age):

{ "@context": {...}, "@id": "...", "@type": "Person", "name": "Alice", "age": 30 }

Complex (nested address + array):

{ "@context": {...}, "@id": "...", "@type": "Person", "name": "Alice", "age": 30, "address": { "@id": ".../address", "street": "123 Main St", "city": "Boston", "state": "MA" }, "tags": ["a","b","c"] }
