continuant part of material entity system system component composante de système componente del sistema A material entity that belongs to a system. system variable Despite minor differences, SCO representation of systems and related architecture and composition is compatible with that of the System Core Ontology (Calhau et al., 2024). The system Core Ontology centers on socio-techno systems, primarily pointing to an intention/goal-directed representation of these systems. SCO representation, instead, adopts a more neutral modeling approach for complex systems, seeking to account for a wider range of systems. SCO is also more compact than the system Core Ontology. This is, however, adequate for the current purposes of SCO. We envision employing the system Core Ontology as a starting point to extend SCO representation of system architecture, situations, properties, and functions. We also envision possible alignments and reciprocal implementations between these two ontologies. Calhau, R.

Insights for discussion may be found in Calhau et al. (2024) and Ubbiali et al. (2024). Calhau, R.
