To all contributors, users, and observers of this repository:
This repository will be formally archived on [March 11, 2026 — one month from posting].
The decision to archive is intended to prevent confusion with similarly named efforts and to avoid ambiguity resulting from the absence of ongoing updates. Current IOF research and development is conducted in the IOF Foundry Organization. Current NCOR developments can be tracked in the NCOR Network Organization.
Archiving this repository will ensure it remains accessible for historical reference while clearly indicating that it is no longer under active development or maintenance.
Please note:
- The repository will remain publicly viewable.
- No new issues, pull requests, or updates will be accepted after the archival date.
- Existing materials will remain available for citation and reference purposes.
If you are currently depending on this repository or believe there are reasons it should remain active, please raise those concerns before the archival date.
Thank you to everyone who has engaged with, contributed to, or followed this work.

This is a repository for the Coordinated Holistic Alignment of Manufacturing Processes (CHAMP) Project -- a DMDII-funded project bringing together the University at Buffalo (SUNY), CUBRC, Inc., and industry partners. The goal of CHAMP is to represent the domain of the Product Life Cycle in a suite of mid-level ontologies that may be extended in applications to integrate data both within industrial organizations and across them.
Here, you will find the suite of ontology files saved in the turtle format.
The ontologies extend from Basic Formal Ontology (BFO), the Relations Ontology (RO), as well as the Common Core Ontologies (CCO) developed by CUBRC.
The Common Core Ontologies have their own github repository here: https://github.com/CommonCoreOntology Basic Formal Ontology and related files may be found here: https://github.com/BFO-ontology
In addition, there are two applications available here: Process Workflow and Ontoview. The former is an ingestion tool with an RDF-backend to support saving and re-using information throughout a mapping process; the latter is a query tool that improves on the typical SPARQL endpoint by allowing non-expert users to 'build-up' queries by browsing RDF data.
