(AureXus) ALTO = Analysed Layout and Text Object (FR : ALTO)

ALTO is a XML schema of metadata for describing the layout and content of physical text resources such as pages of a book or a newspaper. ALTO accurately captures technical details of text pages such as the position of characters, words, paragraphs, illustrations, footnotes, etc. These details make it possible for access systems like Chronicling America, Papers Past, Trove, and Newspapers (and many others) to precisely locate and show a character, word, paragraph, illustration, or footnote on a page image. ALTO is an open standard and may be freely used by anyone. IFLA
