Object-Centric OLAP

The four multi-dimensional operations on an object-centric event log: drill down and roll up along the object-type dimension, unfold and fold along the event-type dimension. Each produces a new OCEL — the same log seen at a different granularity — so every discovery, view and metric in the workspace can be run again on it and the two compared. This is how an object-centric log is analysed the way a cube is: not by filtering it down, but by changing what counts as a type.
