History of XES
History of the XES Standardization
For this transfer and storage, the IEEE Task Force on Process Mining in its meeting at the BPM 2010 conference on September 15th, 2010, initiated the IEEE standardization process for the Extensible Event Stream standard, or XES in short. To guide this process, in September 2012 an initial small XES Working Group (XES WG) was formed, which reached agreement on the XES Standard in 2013. On July 13th, 2014, the IEEE Computational Intelligence Society (IEEE CIS) accepted sponsorship for the XES Standard. The sponsor submitted the Project Approval Request (PAR) to the IEEE Standards Association (IEEE SA), which accepted the PAR on March 26th, 2015. On August 22nd, 2015 the XES Working Group was extended, and submitted the first external version for the XES Standard to the IEEE SA for Mandatory Editorial Coordination on December 2nd, 2015. Some minor changes were made as a result of this coordination, and the second external version went into ballot on February 16th, 2016. This ballot ended on March 18th, 2016, with a 95% response rate, one abstention, and a 100% approval rate. As a result of the comments received during the ballot, the XES WG agreed not to allow for local timestamps in the XES Standard but to require proper UTC timestamps instead. As this change was not considered to be an editorial change, a recirculation of the third external version was required, which was initiated on June 27th, 2016. In this recirculation, no votes were changed, and no more comments were received. As a result, this third ex ternal version of the XES Standard was submitted on July 19th, 2016 to the IEEE SA Revision Committee (RevCom). During its meeting on September 19th, 2016, RevCom recommended this version of the XES Standard to be approved. During its meeting on September 22nd, 2016, IEEE SA accepted this recommendation and approved the third external version of the XES Standard. After a short editorial process, the final version of the XES Standard was published by IEEE SA on November 11th, 2016.
The published 1849-2016 XES Standard can be found in the IEEE Digital Library (through the URL http://ieeexplore.ieee.org/document/7740858/), and can be referred to use the DOI 10.1109/IEEESTD.2016.7740858.In 2022, a new XES Working Group was formed to revise the 1849-2016 XES Standard. This resulted in the 1849-2023 XES Standard, which was published on August 9, 2023, and which has superseded the 1849-2106 XES Standard by that date. The 1849-2023 XES Standard extends the 1849-2016 with all standard extensions that have been accepted before the year 2023.
