Description
Wrappers for converting, expanding and compacting JSON-LD documents. All parameters and return values must be JSON strings. Use jsonlite::toJSON and jsonlite::fromJSON to convert between R objects and JSON format. The readme has basic examples.
Usage
jsonld_compact(doc, context, options = NULL)
jsonld_expand(compacted, options = NULL)
jsonld_flatten(doc, context = NULL, options = NULL)
jsonld_frame(doc, frame, options = NULL)
jsonld_from_rdf(rdf, options = list(format = "application/nquads"))
jsonld_to_rdf(doc, options = list(format = "application/nquads"))
jsonld_normalize(doc, options = list(algorithm = "URDNA2015", format =
"application/nquads"))
Arguments
doc |
a URL or literal string with JSON-LD document |
context |
a URL or literal string with JSON-LD context |
options |
named list with advanced options |
compacted |

Examples
# Example from https://github.com/digitalbazaar/jsonld.js#quick-examples
doc <- '{
"http://schema.org/name": "Manu Sporny",
"http://schema.org/url": {"@id": "http://manu.sporny.org/"},
"http://schema.org/image": {"@id": "http://manu.sporny.org/images/manu.png"}
}'
context <- '{
"name": "http://schema.org/name",
"homepage": {"@id": "http://schema.org/url", "@type": "@id"},
"image": {"@id": "http://schema.org/image", "@type": "@id"}
}'
# Compact and expand:
(out <- jsonld_compact(doc, context))
(expanded <- jsonld_expand(out))
# Convert between JSON and RDF:
cat(nquads <- jsonld_to_rdf(doc))
jsonld_from_rdf(nquads)
# Other utilities:
jsonld_flatten(doc)
cat(jsonld_normalize(doc))
