🏷️Tagging

NEW

Adding labels or keywords to resources for classification and discovery.

DESCRIPTION

Tagging assigns descriptive keywords to resources, enabling flexible categorization and retrieval. It is often user-driven (folksonomy) and complements controlled vocabularies. Tags improve search, recommendations, and navigation in content platforms and data catalogs. Governance balances openness with consistency, using tag normalization and guidelines to reduce ambiguity.
