Python Bindings for OC-DECLARE: Discovering Object-Centric Declarative Patterns with Synchronization
Requires Python: >=3.8
Keywords: process-mining, process, mining, OC-DECLARE, object-centric, DECLARE

# OC-DECLARE

Python bindings for the OC-DECLARE implementation.
OC-DECLARE allows discovering declarative synchronized object-centric process constraints from Object-Centric Event Logs (OCEL) in the OCEL 2.0 format.

More details can also be found in the original paper [OC-DECLARE: Discovering Object-Centric Declarative Patterns with Synchronization](https://doi.org/10.1007/978-3-032-02867-9_11), the [OC-DECLARE GitHub Repo](https://github.com/aarkue/OC-DECLARE), or the [Rust4PM Github Repo](https://github.com/aarkue/rust4pm).

**See below for a usage example. The Jupyter Notebook version of the example is available [on GitHub](https://github.com/aarkue/oc-DECLARE/blob/main/oc_declare_python/example.ipynb).**
