The Industrial Ontologies Foundry (IOF) announced the 202401 release of its suite of ontologies. Historically, this is the second release. The release contains enhancements to the IOF Core Ontology. They include constructs that enable precise expressions of temporal relations between events and processes and powerful constraint-checking and inferencing capabilities on them. The flexibility to use XML schema datetime data types or OWL Time for expressing temporal values was also provided.
Along with this new release of the IOF Core ontology, the IOF user community now has consistent, streamlined, and interoperable usage patterns for a rich vocabulary of quantity kinds and associated units of measure that can be migrated to a forthcoming IOF quantity and unit ontology.
The IOF Core team collaborated with maintainers of the Quantity, Unit, Dimension and Type (QUDT) Ontology to make an OWL-compliant version (v2.1.3.4). This not only makes QUDT readable in an OWL editor but also enables certain reasoning when following the non-normative guideline document for using QUDT with IOF ontologies.
Other notable enhancements include the representation of how and when roles are gained and lost, along with the promotion and improvement of terms from the Supply Chain Ontology that are applicable across many domains. The IOF Core Ontology continues to evolve as a foundational resource for semantic interoperability across diverse domains.
