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)
• :gzip: Allows to read directly from a gzipped file (default: false)
• :file_mode: A list with the Elixir File.open modes to be used for reading (default: [:read, :utf8])

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.

Specs

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.

Specs

read_stream(Enumerable.t(), keyword()) ::
  {:ok, RDF.Graph.t() | RDF.Dataset.t()} | {:error, any()}

Deserializes a graph or dataset from a stream.

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

Specs

read_stream!(Enumerable.t(), keyword()) :: RDF.Graph.t() | RDF.Dataset.t()

Specs

read_string(String.t(), keyword()) ::
  {:ok, RDF.Graph.t() | RDF.Dataset.t()} | {:error, any()}

Deserializes a graph or dataset from a string.

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

Specs

read_string!(String.t(), keyword()) :: RDF.Graph.t() | RDF.Dataset.t()

Deserializes a graph or dataset from a string.

Specs

write_file(RDF.Data.t(), Path.t(), keyword()) :: :ok | {:error, any()}

Serializes a RDF data structure to a file.

It returns :ok if successful or {:error, reason} if an error occurs.

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)
• :file_mode: A list with the Elixir File.open modes to be used for writing (default: [:write, :exclusive])

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