compact(input, context, options \\ %Options{})

View Source

Compacts the given input according to the steps in the JSON-LD Compaction Algorithm.

Compaction is the process of applying a developer-supplied context to shorten IRIs to terms or compact IRIs and JSON-LD values expressed in expanded form to simple values such as strings or numbers. Often this makes it simpler to work with document as the data is expressed in application-specific terms. Compacted documents are also typically easier to read for humans.

context(context, options \\ %Options{})

View Source

Generator function for JSON.LD.Contexts.

You can either pass a map with a "@context" key having the JSON-LD context object its value, or the JSON-LD context object directly.

This function can be used also to create JSON.LD.Context from a RDF.PropertyMap.

expand(input, options \\ %Options{})

View Source

Expands the given input according to the steps in the JSON-LD Expansion Algorithm.

Expansion is the process of taking a JSON-LD document and applying a @context such that all IRIs, types, and values are expanded so that the @context is no longer necessary.

flatten(input, context \\ nil, options \\ %Options{})

View Source

Flattens the given input according to the steps in the JSON-LD Flattening Algorithm.

Flattening collects all properties of a node in a single JSON object and labels all blank nodes with blank node identifiers. This ensures a shape of the data and consequently may drastically simplify the code required to process JSON-LD in certain applications.

read_file!(file, opts \\ [])

View Source
@spec read_file!(
  Path.t(),
  keyword()
) :: RDF.Graph.t() | RDF.Dataset.t()

Deserializes a graph or dataset from a file.

As opposed to read_file/2, it raises an exception if an error occurs and defaults to stream: true.

See read_file/3 for the available format-independent options.

See the module documentation of the decoder for the available format-specific options, all of which can be used in this function and will be passed them through to the decoder.

read_file(file, opts \\ [])

View Source
@spec read_file(
  Path.t(),
  keyword()
) :: {:ok, RDF.Graph.t() | RDF.Dataset.t()} | {:error, any()}

Deserializes a graph or dataset from a file.

It returns an {:ok, data} tuple, with data being the deserialized graph or dataset, or {:error, reason} if an error occurs.

Options

General serialization-independent options:

  • :stream: Allows to enable reading the data from a file directly via a stream (default: false on this function, true on the bang version)

Options

General serialization-independent options:

  • :stream: Allows to enable writing the serialized data to the file directly via a stream. Possible values: :string or :iodata for writing to the file with a stream of strings respective IO lists, true if you want to use streams, but don't care for the exact method or false for not writing with a stream (default: false on this function, :iodata on the bang version)
  • :gzip: Allows to write directly to a gzipped file (default: false)
  • :force: If not set to true, an error is raised when the given file already exists (default: false)
