rdf-jsonld

JSON-LD, YAML-LD, and CBOR-LD parser and serializer classes for the ZuzuScript rdf distribution.

This trial distribution provides:

• JsonLdParser, YamlLdParser, CborLdParser, and CompressedCborLdParser.
• JsonLdSerializer, YamlLdSerializer, CborLdSerializer, and CompressedCborLdSerializer.
• Shared JSON-LD 1.1 ToRDF and FromRDF helpers.
• Author-gated tests using the official W3C JSON-LD API test suite.

The YAML-LD and CBOR-LD classes use the same JSON-LD data model as JSON-LD itself, with std/data/yaml and std/data/cbor handling the surface syntax. The compressed CBOR-LD classes use the CBOR-LD tag profile and registry entry 1 by default.

Example

from rdf/parser/jsonld import JsonLdParser;
from rdf/serializer/jsonld import JsonLdSerializer;

let quads := ( new JsonLdParser() ).parse_string("""
{
  "@context": {"ex": "http://example.com/"},
  "@id": "ex:s",
  "ex:p": "value"
}
""", base: "http://example.com/doc");

say( ( new JsonLdSerializer( pretty: true ) ).serialize(quads) );

Parsers compose the RdfParser trait from rdf/parser and support parse_string, parse_file, parse_lines, and parse_chunks. They accept the same base and into options as the main RDF parsers.

Serializers compose the RdfSerializer trait from rdf/serializer and support serialize and serialize_each.
