An encoder for Turtle serializations of RDF.ex data structures.

As for all encoders of RDF.Serialization.Formats, you normally won't use these functions directly, but via one of the write_ functions on the RDF.Turtle format module or the generic RDF.Serialization module.

Options

• :prefixes: Allows to specify the prefixes to be used as a RDF.PrefixMap or anything from which a RDF.PrefixMap can be created with RDF.PrefixMap.new/1. If not specified the ones from the given graph are used or if these are also not present the RDF.default_prefixes/0.
• :base: : Allows to specify the base URI to be used for a @base directive. If not specified the one from the given graph is used or if there is also none specified for the graph the RDF.default_base_iri/0.
• :implicit_base: This boolean flag allows to use a base URI to get relative IRIs without embedding it explicitly in the content with a @base directive, so that the URIs will be resolved according to the remaining strategy specified in section 5.1 of RFC3986 (default: false).
• :base_description: Allows to provide a description of the resource denoted by the base URI. This option is especially useful when the base URI is actually not specified, e.g. in the common use case of wanting to describe the Turtle document itself, which should be denoted by the URL where it is hosted as the implicit base URI.
• :only: Allows to specify which parts of a Turtle document should be generated. Possible values: :base, :prefixes, :directives (means the same as [:base, :prefixes]), :triples or a list with any combination of these values.
• :indent: Allows to specify the number of spaces the output should be indented.
