See “see also” annotation”. As these relations apply specifically to the CCO “Agent” class and lack reference to time, the SCO creator decided to establish SCO's own versions of these relations, directly referring to the original source. See “adapted from” annotation. Future implementations may involve the introduction of an “act within the system” class, to deepen the characterization of system agency. Insights to implementation may come from the following CCO classes: http://www.ontologyrepository.com/CommonCoreOntologies/Act http://www.ontologyrepository.com/CommonCoreOntologies/IntentionalAct http://www.ontologyrepository.com/CommonCoreOntologies/Agent http://www.ontologyrepository.com/CommonCoreOntologies/AgentCapability The aim is to align SCO and CCO “agent” classes in order to have a shared theory of agency. comments to https://www.w3id.org/sco/sco-u#SCO_0000027 and https://www.w3id.org/sco/sco-u#SCO_0000029 Une relation primitive entre un processus x, un continuant y et un temps t auquel y est causalement actif en x.

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.
