Event Logs

Our event log collection spans a wide range of sizes, from lightweight logs that download and load quickly to large, real-world logs that can require more memory and longer loading times. If you want something small and easy to start with, we recommend the LRMs Collection and Inventory Management datasets, or Hinge Production (only a few thousand events). The mid-sized logs—such as Procure-to-Pay (P2P), Order Management, Logistics, Scientific Publications, and Angular GitHub Commits—are typically comfortable to work with on a standard laptop. The largest datasets—such as (Un)Fair, German Bundestag, Enron emails, AoE2 gameplay, and the Ethereum blockchain—range from hundreds of MB up to GB-scale, so we suggest starting with any provided smaller subsets/checkpoints (e.g., Enron’s smaller checkpoints or AoE2’s small sample) before scaling up.

A check mark means that the Zenodo record provides the log in that format. Bundled ZIP refers specifically to the OCEL 2.1 multi-table .ocel.zip format, not a ZIP file used only to compress another format.
