VynFi Supply Chain OCEL (v5.29 SOTA mode)

Native OCEL 2.0 event log for a 5-company manufacturing supply chain. Sister dataset to `VynFi/vynfi-journal-entries-1m` — same v5.29 generator, same SOTA-N behavioral lever stack + central ConcentrationPipeline, but materialised as an object-centric event log (events + objects + relationships) instead of a flat GL.

Why four configs

OCEL 2.0 is a multi-table schema by design. Selecting just one "default" split would lose 90 % of the signal. The four configs below are sized so each can be loaded independently for the analyses they support.

Load with load_dataset(repo, name=<config_name>). The events config is the canonical OCEL log most process-mining tools (pm4py, ProM, Celonis) consume.

Structural quality (vs reference)

Same v5.29 SOTA lever stack as the JE datasets; see `vynfi-journal-entries-1m` for the 13-row structural-metric table. The lever effects propagate through the OCPM event-log construction (P2P/O2C process chains inherit the same SOTA-N behavioral patterns).

Dataset scope

• —5 companies × 12 months × `Custom(300_000)` (heap cap raised to 64 GB for VM-class regen)
• —~320 K OCEL events, ~7.4 K objects across P2P/O2C/manufacturing process types
• —Method-A flat edge list (je_network.parquet) joinable to events via shared document_id + entry date
• —Multi-currency (USD/EUR/SGD)

Quick start

from datasets import load_dataset

events = load_dataset("VynFi/vynfi-supply-chain-ocel", name="events")
objs   = load_dataset("VynFi/vynfi-supply-chain-ocel", name="objects")
print(events["train"].num_rows, "events")   # ~320,459
print(objs["train"].num_rows, "objects")    # ~7,439

For an end-to-end OCEL 2.0 file, the events + objects + relationships roll up into the ocel_json output the engine writes during generation; the parquet split here is for tabular consumers.

Generation config

configs/examples/hf/supply_chain_ocel_sota.yaml in `mivertowski/SyntheticData @ v5.29.0`.

datasynth-data validate --config supply_chain_ocel_sota.yaml
