For several years now, digital projects and editions have been dealing with many varieties of correspondence. The encoding of letters 1 and the methodological reection on this process have a long tradition in the TEI. One early achievement in this area was the Model Editions Partnership: Historical Editions in the Digital Age 2 (MEP), developed during the 1990s, which provided several sample editions of historical documents, including letters. On the basis of these, the project editors reected on new approaches and a general model for preparing digital editions.Working with SGML (later XML) and TEI, a number of custom MEP elements were added to the ocial TEI elements for the marking up of letter-specic phenomena, for example, the sender and addressee, typical closing phrases, or a postscript (, , , ).
