COPI is a domain-core ontology for petroleum production plants. It provides a domain-level semantic backbone by specializing BFO 2020 and IOF-Core, supporting semantic interoperability across heterogeneous industrial standards and datasets.
In scope:
- Material entities composing petroleum production plants
- Functional locations used to organize and manage physical assets
- Information artifacts describing assets, locations, and plant documentation
Out of scope:
- Real-time control logic
- Numerical simulation models
- Business process modeling beyond asset lifecycle representation
- Semantic integration of heterogeneous plant data sources
- Support for querying asset hierarchies and functional locations
- Alignment and comparison between industrial standards
- Serving as a semantic foundation for domain-specific application ontologies
Intended end-users: ontology engineers, asset integrity engineers, maintenance engineers, and industrial data integration specialists.
COPI is designed to be correlatable and alignable with:
| Standard | Description |
|---|---|
| ISO 15926-4 | Reference Data Library (RDL) |
| ISO 14224 | Reliability and maintenance of equipment |
| CFIHOS | Capital Facilities Information Handover Specification |
| DEXPI | Data Exchange in the Process Industry |
| POSC Caesar RDL | Reference Data Library |
Artefacts are published at https://www.inf.ufrgs.br/ontologies/copi/ and generated automatically on every push to main via GitHub Actions using ODK.
