Alidomainin

Alidomainin is a conceptual model used in discussions of information architecture and distributed systems to describe the organization and governance of content across multiple subdomains within a primary domain. In this model, a central domain delegates administrative responsibility to subordinate subdomains, allowing each to manage its own resources, access controls, and data policies while inheriting overarching rules from the parent domain.

Origin and terminology: The term appears in theoretical writings and practitioner handbooks in the 2010s and 2020s as a compound of "ali-" meaning sub- or under and "domainin" from domain, reflecting its hierarchical nature. Usage varies by context, and the concept is treated as a flexible guideline rather than a strict standard.

Structure and dynamics: A typical alidomainin setup includes a root domain, a set of alidomainin units (subdomains) with defined administrative boundaries, and resources. Policy inheritance allows default permissions to flow down while exceptions can be defined at the subdomain level. Cross-subdomain communication may be governed by explicit interfaces and access control lists.

Applications and challenges: It is discussed in corporate intranets, cloud deployments, and content management systems as a way to improve scalability, privacy, and autonomy. Critics point to increased management overhead, potential inconsistency of policies, and complex security modelling.
