About OCPQ

OCPQ is a software tool for (object-centric) process querying. It aims to be easy to use, powerful in expressiveness and very fast. The source code of OCPQ is available at github.com/aarkue/OCPQ.

OCPQ is powered by the Rust4PM project, which provides a robust foundation for process mining in Rust. Rust4PM handles the efficient data import and export, as well as the core data structures for object-centric event logs and process models (including OC-DECLARE).
