participates in agent in at time t agent en au temps t agente in al tempo t A primitive relation between a continuant x, a process y, and a time at which x is causally active in y. See information under the inverse "has agent at t" property. We envision revisions of the current SCO theory of agency. This is due to the limited power of explainability of present representation. A sounder and deeper interpretation of the causal role of an agent in an interaction, compared to other participants, is required. Tentative proposal: a possible direction of implementation is towards a telic vision of agency intended as end-point driven. On this more fundamental neutral vision, a second layer of representation may be constructed to model intentionality, goals, and plans in relation to agency. Here, SCO may harmonize and align with UFO-C representation. For insight for discussion see: Guarino, N., & Guizzardi, G. (2024). Processes as variable embodiments.
