Install

$ yarn add @comunica/actor-rdf-parse-jsonld

Configure

After installing, this package can be added to your engine's configuration as follows:

{
  "@context": [
    ...
    "https://linkedsoftwaredependencies.org/bundles/npm/@comunica/actor-rdf-parse-jsonld/^2.0.0/components/context.jsonld"  
  ],
  "actors": [
    ...
    {
      "@id": "urn:comunica:default:rdf-parse/actors#jsonld",
      "@type": "ActorRdfParseJsonLd",
      "priorityScale": 0.9,
      "mediatorHttp": { "@id": "urn:comunica:default:http/mediators#main" }
    }
  ]
}

Config Parameters

priorityScale: An optional priority for this parser, used for content negotiation, defaults to 1.
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.

Usage no npm install needed!
