OCEL 2.0 Resources -- www.ocel-standard.org
Istvan Koren, Niklas Adams, Alessandro Berti · 2024-03-04 · via cs.DB updates on arXiv.org

Process mining has become a cornerstone of process analysis and improvement over the last few years. With the widespread adoption of process mining tools and libraries, the limitations of traditional process mining to deal with event data with multiple case identifiers, i.e., object-centric event data, have become apparent. As a response, the subfield of object-centric process mining has formed, including a file format standardization attempt in the form of OCEL 1.0, unifying the insights of previous developments in capturing object-centric event data. However, discussions among researchers and practitioners have shown that the proposed OCEL 1.0 standard does not go far enough. OCEL 2.0 has been proposed as an advanced refinement, including normative and explicit object-to-object relationships, qualifiers for object-to-object and event-to-object relationships, and evolving object attribute values. This demonstration presents the OCEL 2.0 website available under the URL https://www.ocel-standard.org as a one-stop shop for the detailed specification, example event logs, and broad tool support to facilitate the adoption of the format.
