#initialize(term, id: nil, index: nil, type_mapping: nil, container_mapping: nil, language_mapping: nil, direction_mapping: nil, reverse_property: false, nest: nil, protected: nil, simple: false, prefix: nil, context: nil) ⇒ TermDefinition

Create a new Term Mapping with an ID

Parameters:

  • term (String)
  • id (String) (defaults to: nil)
  • type_mapping (String) (defaults to: nil)

    Type mapping

  • container_mapping (Set<'@index', '@language', '@index', '@set', '@type', '@id', '@graph'>) (defaults to: nil)
  • language_mapping (String) (defaults to: nil)

    Language mapping of term, false is used if there is an explicit language mapping for this term

  • direction_mapping ("ltr", "rtl") (defaults to: nil)

    Direction mapping of term, false is used if there is an explicit direction mapping for this term

  • reverse_property (Boolean) (defaults to: false)
  • protected (Boolean) (defaults to: nil)

    mark resulting context as protected

  • nest (String) (defaults to: nil)

    term used for nest properties

  • simple (Boolean) (defaults to: false)

    This is a simple term definition, not an expanded term definition

  • prefix (Boolean) (defaults to: nil)

    Term may be used as a prefix
