A taxonomy is a structured system that organizes content through controlled vocabularies, helping with information retrieval by tagging items with predefined terms. It complements user-visible navigation by categorizing content based on metadata, improving search suggestions, and faceted navigation. Taxonomies differ from IA structures, which organize content hierarchically, and from thesauri and ontologies, which have more complex relationships. Properly implemented, a taxonomy streamlines content discovery and enhances user experience
