Any printed or digital scholarly edition of letters can provide their indexes of letters in correspDesc format and register the corresponding URL for the correspSearch web service. Here's how it works:
In the Step-by-Step-Manual you'll learn how to search for authority file IDs and how to create a digital index of edited letters with the CMIF Creator.
With the CMIF Creator you can create a digital index of letters of your printed editions in CMI format without any knowledge of XML.
With the preview you can check your CMIF file more easily and get a first overview of the data. No data is stored on our server! Processing may take a few seconds.
Klaus Rettinghaus has developed a Python script that converts CSV tables into CMIF files. The script and the manual can be found on the GitHub account of the SAW-Leipzig.
SAW Leipzig now also offers a corresponding webapp that enables the transformation online. [To the CSV2CMI webapp]
