====== OpenXES ======

OpenXES (pronounced as "open excess") is a reference implementation of the [[:xesstandarddefinition|First XES standard]] for storing and managing event log data. Application domains of the First XES standard, and the OpenXES library, are manifold. They include, but are not limited to monitoring of process-aware information systems, [[http://processmining.org/|process mining]] and general process analysis, and data mining.

XES is an open standard for storing and managing event log data. The OpenXES library is a reference implementation of that standard in [[http://java.sun.com/|Java™]], which strives for strict XES compatibility, ease of development, and the best possible performance. OpenXES is released as [[http://www.opensource.org/|open source]] / [[http://www.fsf.org/about/what-is-free-software|free software]], under the terms of the [[http://www.xes-standard.org/downloads/LICENSE.txt|GNU Lesser GPL]] (LGPL) license.

Both the First XES standard and OpenXES have been designed with a tightly reduced, generally applicable core definition, with extensibility and generic applicability in mind. The First XES standard provisions a generic extension system, which can be used to store data from arbitrary perspectives, or from specific application domains (e.g., for mapping corporate data models).
