TEI is the XML standard for digitising literary and historical texts in the humanities. The Text Encoding Initiative is the scholarly standard for marking up old manuscripts and books. The Text Encoding Initiative traces back to a 1987 planning meeting at Vassar College and is maintained by an international consortium. Its guidelines were originally written in SGML before moving to XML with the P4 revision in 2002 - the P5 generation of 2007 then dropped SGML entirely.
