In a digital work of historical-cultural content information can practically assume all the formats allowed by current technology.

As text information we understand all the written texts with relevant ( necessarily linguistic and partly notional ) independence, of whatever length . In practice this means all types of texts, wither purely narrative ones or auxiliary ones ( introductions and guidelines for use, glossaries, captions, chronologies, footnotes, bibliographies, quotations, list of works by a specific writer, genealogy trees, catalogues and tables etc).



Visual and audiovisual information
These are files of static or animated images that are accompanied or not by sound. They include photographs , rough drafts, architectural drawings and representations (in two or three dimensions), maps, graphs, videos and various versions of combinations of static or animated images. Sound information It includes speech, music and any type of sound recordings, either accompanying images (narration, commentary, soundtrack, sound or film document) or as autonomous files (narration, testimony, recitation, discussion, singing etc).
