The Offshore Petroleum Production Plant Ontology (O3PO) is a bilingual, BFO‑aligned domain ontology that formally represents knowledge about offshore oil and gas production systems.
It was introduced in the paper:
Santos, N. O., Rodrigues, F. H., Schmidt, D., Romeu, R. K., Nascimento, G., & Abel, M. (2024).
O3PO: A domain ontology for offshore petroleum production plants.
Expert Systems with Applications, 238 (Part F), 122104.
https://doi.org/10.1016/j.eswa.2023.122104
O3PO supports semantic data integration, interoperability, and reasoning over industrial asset information.
It provides a structured vocabulary for modeling production systems, equipment, processes, and information artifacts found in offshore petroleum facilities.

O3PO directly imports the following ontologies:
| Ontology | Version / IRI | Purpose |
|---|---|---|
| BFO – Basic Formal Ontology | http://purl.obolibrary.org/obo/bfo/2020/bfo.owl | Upper-level ontology providing core categories (Object, Process, Quality, etc.) |
| IAO – Information Artifact Ontology | http://purl.obolibrary.org/obo/iao/2022-11-07/iao.owl | Metadata and information content entities |
| IOF-Core | https://spec.industrialontologies.org/ontology/202401/core/Core/ | Common industrial foundation for Artifact, Process, and Function |
| GeoCore | https://www.inf.ufrgs.br/bdi/ontologies/geocore/releases/2024-04-06/geocore.owl | Spatial and geoscientific extensions |
This repository maintains only the current canonical ontology version for public use:
o3po.ttl– canonical OWL 2 DL version (bilingual, normalized IRIs)
All entities use the base namespace:
https://www.inf.ufrgs.br/ontologies/o3po#
O3PO conforms to the OWL 2 DL profile and is compatible with reasoners such as HermiT, Pellet, and FaCT++.
Datatype usage (xsd:dateTime, xsd:decimal, xsd:boolean, etc.) follows OWL 2 DL constraints.
