A preliminary quantities and units ontology was developed for FIBO for use with commodities. Several other groups at OMG need this ontology, as do external users of the Commons library. The ontology should be mappable to the SysML v2 library so that we can generate the individuals in that library for use in knowledge graph applications. It should also be consistent, to the degree possible, with the latest changes to the VIM, with BIPM requirements, and with ISO 11240 for use in the pharmaceutical domain.

There is a dependency in the quantities and units ontology on a small documents ontology, to provide the reference documentation for certain units. This ontology is relatively small, however, and can easily be mapped to other ontologies defining documents.

A situation is a complex, typically time-bound, setting, state of being, or relationship that is relatively stable for some period of time. An ontology defining such situations, including the complex property chains that link the actors and undergoers in such situations to the roles that they play is essential in finance, pharma, retail, robotics, and many other industries.

A well-tested ontology that describes these patterns would be a useful addition to the Commons library. In addition, this ontology (and the new composition ontology on which it depends) is urgently needed for the Robotics Service Ontology (RoSO), whose planned revised submission is planned for September 2023.

Note that the resolution of this issue requires the ontology added under COMMONS-11-4.

Currently we have an explicit date period, but not explicit time period, which is needed for PPMN, among other processes. This is also required for Robotics.

After additional review, RTF members suggested that a better name for the ontology would be roles and compositions. Other feedback identified a typo, suggested that we add the notion of independent identity in the definition of composition for clarification, and remove the functional axiom on the property isPlayedBy, which might overly constrain its utility.

In pharmaceuticals and other industries, products are often composed of other things. The 'recipe' for manufacturing a product includes various ingredients, which are roles that substances, components. or other things take on in the context of that product.

Further, there are cases where the composition of some product is context specific. Product documentation may be jurisdictionally defined due to regulatory constraints, for example. The representation of some ingredients in certain pharmaceutical products, including the way these elements are described on packaging, is jurisdiction specific, even thought the product itself has exactly the same composition via exactly the same manufacturing processes world wide.

A general pattern for this kind of composition would be quite useful for a number of domain areas and is a good candidate for inclusions in the Commons library.

This is needed for representation of tensor and vector quantities for the quantities and units ontology, and for representation of certain machine learning algorithms, among other requirements.
