An implementation of the JSON-LD 1.1 standard for Elixir and RDF.ex.
The API documentation can be found here. For a guide and more information about RDF.ex and it's related projects, go to https://rdf-elixir.dev.
- fully conforming JSON-LD 1.1 API processor
- JSON-LD reader/writer for RDF.ex
- customizable HTTP client for remote document loading
- tests of the JSON-LD test suite (see her 8000 e for the EARL reports)

dataset = JSON.LD.read_file!("file.jsonld")
JSON.LD.write_file!(dataset, "file.jsonld")When a context is provided via the :context option (as a map, a RDF.PropertyMap or a string with a URL to a remote context), the document gets automatically compacted on serialization.
JSON.LD.write_file!(dataset, "file.jsonld", context: %{ex: "https://example.com/"})
JSON.LD.write_file!(dataset, "file.jsonld", context: "https://schema.org/")Pretty printing is possible on all writer functions with all the formatter options of Jason, the underlying JSON encoder, to which the given options are passed through.
JSON.LD.write_file!(dataset, "file.jsonld", pretty: true)
JSON.LD.write_string(dataset, "file.jsonld", pretty: [indent: "\t"])see CONTRIBUTING for details.
