Configure

After installing, this package can be added to your engine's configuration as follows:
`text
{
"@context": [
...
"https://linkedsoftwaredependencies.org/bundles/npm/@comunica/actor-rdf-parse-jsonld/^5.0.0/components/context.jsonld"
],
"actors": [
...
{

$3

* priorityScale: An optional priority for this parser, used for content negotiation, defaults to 1.
* httpInvalidator: An optional actor that listens to HTTP invalidation events.
* cacheSize: The maximum number of fetched remote JSON-LD documents (including contexts) in the LRU cache, set to 0 to disable, defaults to 128.
* mediatorHttp: A mediator over the HTTP bus, for fetching remote JSON-LD contexts.

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.

$3

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.

$3

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.
