A Note on the Compatibility of Part-Whole Relations with Foundational Ontologies

Parthood in mereology is one relation, and typically is included in foundational ontologies. Some of these foundational ontologies and many domain ontologies use a plethora of parthood and part-whole relations, such as ‘sub process’ and ‘portion’. This poses requirements on the foundational ontologies and, perhaps, Ontology, on what to do with these two different approaches to part-whole relations. We present an analysis of DOLCE, BFO, GFO, SUMO, GIST, and YAMATO on their inclusion and use of part-whole relations. It demonstrates there is no perfect fit with either for various reasons. We then aim to bridge this gap with an orchestration of ontologies of part-whole relations that are aligned to several foundational ontologies and such that they can be imported into other ontologies.
