Namespace management is the discipline of allocating, resolving, and governing the prefixes and base IRIs that disambiguate identifiers in a data or knowledge system. It ensures that terms drawn from different vocabularies do not collide and that abbreviated CURIE-style names resolve consistently to canonical IRIs. Effective namespace management is foundational for interoperable metadata, ontology reuse, and stable linked-data references.

Poor namespace hygiene produces clashing terms, broken links, and ambiguous queries, so registries enforce uniqueness and provide authoritative resolution of each registered namespace.
