Domainien
Domainien is a theoretical construct used to model the interactions between distinct semantic or operational domains within a complex system. A domain is a self-contained set of rules, entities, and behaviors; examples include software service domains, regulatory authorities, or scientific disciplines. Domainien act as mediators that enable cross-domain exchange while preserving the internal constraints of each domain.
Formally, a domainien is described by a boundary relation, a set of invariants that must hold within
Applications include model-driven engineering, where domainien help reason about multi-domain workflows; data governance, where they support
Etymology and usage: the form domainien derives from the root 'domain' with the suffix -ien to indicate
