A type of narrative data that provides "immediate signification," such as names of places, characters, characters' professions, etc. For example, in David Lean's Great Expectations, most informants are transferred from the novel to the film: e.g. names of places ("Satis House," the "Barnard Inn") and characters ("Pip," "Mrs. Havisham," "The Pale Young Genteleman") are retained, as are characters' professions (Jaggers: lawyer, Wemmick: clerk, Joe: blacksmith) and other data (Mrs. Havisham's clocks are stopped at 20 of nine.) But in Alfonso Cuaron's 1998 version, only a few informants (e.g. "Estella") are transferred. Transfer of informants suggests a step towards mimesis in adaptation.
