Why (and how) to use a metaphysicalist foundational ontology

BORO is a metaphysically grounded foundational ontology developed specifically for use with computer systems (a foundational ontology is a system of general domain-independent ontological categories that can form a foundation for domain-specific ontologies; some but not all of these are grounded in metaphysics) and an associated methodology for legacy re-engineering systems. It emerged from a number of system replacement projects that started in the late 1980s. It was developed to mine the ontology-based conceptual models from legacy systems for use in the development of next generation systems. Once the re-engineering methodology was established in the initial projects, questions arose as to where it could usefully be deployed. To answer this, it would help to understand why it was effective; after all, it would be hard to find a more abstract and esoteric subject than metaphysics – and one that does not immediately seem related to computing. Furthermore metaphysics is a broad subject, it would be good to understand better what areas of metaphysics are important, why they are important and how they are useful. It would also be good to have a better idea of where in computing metaphysics could play a useful role. The purpose of this position paper is to sketch out how BORO has, over the decades, developed a view that provides answers to these questions (with no claim that this is the only way to answer them). This view is framed by two related themes. The first is that a new kind of information quality – which we label ‘computerate’ – is needed for computer systems and the second that metaphysics provides the right apparatus for grounding foundational ontologies that can be used to produce this ‘computerate’ information.
