extrinsic element


n. ~ The physical and formal characteristics that constitute a document's material nature and appearance, independent of its intellectual content.


Extrinsic elements include medium, script1, language, special signs, seals, and annotations.

(InterPARES Authenticity, p. 5) Extrinsic elements refer to specific, perceivable features of the record that are instrumental in communicating and achieving the purpose for which it was created. For electronic records, these include: overall presentation features (e.g., textual, graphic, image, sound, or some combination of these); specific presentation features (e.g., special layouts, hyperlinks, colors, sample rate or sound files); electronic signatures and electronic seals (e.g., digital signatures); digital time stamps; other special signs (e.g., digital watermarks, an organization's crest or personal logo).
