In the original definition, INO developers define this class with respect to interactors involved in the interaction process. INO includes the classes “interactor” and “interactor role” (see SeeAlso note). Here, we generalize this definition, excluding reference to interactors. In the context of SCO, we aim to provide users with an upper-level class that generally points to the involvement of material entities in an interaction process mutually influencing each other. We suggest not using this class directly but, instead, extending SCO-provided subclasses as needed. We wish users to classify interactions according to whether they occur among system components, among system environment components, or between system and system environment components. Original definition: “Interaction is a processual entity that has two or more participants (i.e., interactors) that have an effect upon one another.” Un processus qui a au moins deux continuants indépendants (pas de régions spatiales) comme participants, ayant un effet l’une sur l’autre. Un processo che ha almeno due continuanti indipendenti (no regioni spaziali) come partecipanti, aventi un effetto l’una sull’altra. interaction among system components Interaction entre les composantes de système interazione tra le componenti del sistema interaction among system environment components interaction entre les composantes de l’environnement de système interazione tra le componenti dell’ambiente di sistema interaction between system components and system environment components Interaction entre les composantes de système et les composantes de l’environnement de système interazione tra le componenti del sistema e le componenti de l'ambiente del sistema released
