ProM is an extensible framework that supports a wide variety of process mining techniques in the form of plug-ins. Plug-ins currently support the import of and the conversion between several process modelling languages, including Petri nets (PNML, TPN), EPCs/EPKs (Aris graph format, EPML), and YAWL. Mining, analysis, and log filtering plug-ins are also available.
Logsmith is an extendable framework for processing and editing small text files. It can be seen as a combined (but stripped down) version of UN*X tools like awk, sed, and grep with a graphical user interface. The intent is to give users the powers such tools provide without having to train them in their use. In order to archive this goal, logsmith can easily be customized through a plugin architecture to perform the commons tasks that a specific user base might require.
