MXML (Mining eXtensible Markup Language)
MXML emerged in 2003 and was later adopted by the process mining tool ProM. Using MXML, it is possible to store event logs using an XML-based syntax. MXML was the defacto standard format for storing event logs and was used as the native input format for ProM until XES (eXtensible Event Stream) emerged as the new standard for storing event logs.
