]
}
Config Parameters
priorityScale: An optional priority for this parser, used for content negotiation, defaults to1.mediatorHttp: A mediator over the HTTP bus, for fetching remote JSON-LD contexts.
Passing custom options
If you want to pass custom options to the JSON-LD parser,
you can use the '@comunica/actor-rdf-parse-jsonld:parserOptions' context entry
to provide parser options as a hash.
Using a custom document loader
If you want to override how the JSON-LD parser loads external contexts,
you can pass a custom document loader via the '@comunica/actor-rdf-parse-jsonld:documentLoader' context entry.
This document loader must implement the IDocumentLoader interface.
Enabling stricter parsing mode
Via the '@comunica/actor-rdf-parse-jsonld:strictValues' context entry,
you can set the JSON-LD parser to run in a more strict mode.
This corresponds to the strictValues option in JSON-LD Streaming Parser.
