"Scope note: \nThis property associates an instance of E73 Information Object with an instance of E90 Symbolic Object (or any of its subclasses) that was included in it.\nThis property makes it possible to recognise the autonomous status of the incorporated signs, which were created in a distinct context, and can be incorporated in many distinct self-contained expressions, and to highlight the difference between structural and accidental whole-part relationships between conceptual entities. It accounts for many cultural facts that are quite frequent and significant: the inclusion of a poem in an anthology, the re-use of an operatic aria in a new opera, the use of a reproduction of a painting for a book cover or a CD booklet, the integration of textual quotations, the presence of lyrics in a song that sets those lyrics to music, the presence of the text of a play in a movie based on that play, etc. In particular, this property allows for modelling relationships of different levels of symbolic specificity, such as the natural language words making up a particular text, the characters making up the words and punctuation, the choice of fonts and page layout for the characters.\nA digital photograph of a manuscript page incorporates the text of the manuscript page\nIt is an implicit transitive property.\n\nExamples:\t\n\n- The content of Charles-Mo\u00EFse Briquet\u2019s \u2018Les Filigranes: dictionnaire historique des marques du papier\u2019 (E32) P165 incorporates the visual aspect of the watermark used around 1358-61 by some Spanish papermaker(s) and identified as \u2018Briquet 4019\u2019 (E37)\n- The visual content of Jacopo Amigoni\u2019s painting known as \u2018The Singer Farinelli and friends\u2019 (E38) P165 incorporates the musical notation of Farinelli\u2019s musical work entitled \u2018La Partenza\u2019 (E73)\n- The visual content of Nicolas Poussin\u2019s painting entitled \u2018Les Bergers d\u2019Arcadie\u2019 (E38) P165 incorporates the Latin phrase \u2018Et in Arcadia ego\u2019 (E33)\n\nIn First Order Logic:\nP165(x,y) \u2283 E73(x)\nP165(x,y) \u2283 E90(y)\nP165(x,y) \u2283 P106(x,y)"^^ . . . . . .
