  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.
