Analyzed Layout and Text Object
open-in-new
<p>Analyzed Layout and Text Object (ALTO) is an open <a href="/facts/XML/clNgUfWk">XML</a> Schema developed by the EU-funded project called METAe. </p><p>The standard was initially developed for the description of text <a href="/facts/Optical_character_recognition/kdTyxa1l">OCR</a> and layout information of pages for digitized material. The goal was to describe the layout and text in a form to be able to reconstruct the original appearance based on the digitized information - similar to the approach of a lossless image saving operation. </p><p>ALTO is often used in combination with <a href="/facts/Metadata_Encoding_and_Transmission_Standard/mmhTYXPd">Metadata Encoding and Transmission Standard</a> (METS) for the description of the whole digitized object and creation of references across the ALTO files, e.g. reading sequence description. </p><p>The standard is hosted by the Library of Congress since 2010 and maintained by the Editorial Board initialized at the same time. </p><p>In the time from the final version of the ALTO standard in June 2004 (version 1.0) ALTO was maintained by CCS <a href="http://content-conversion.com">CCS Content Conversion Specialists GmbH, Hamburg</a> up to version 1.4. </p>
