Taxonomy and taxonomy governance are different things: the taxonomy is the vocabulary and category structure itself, while governance is the process that keeps it from drifting into inconsistency as more people add tags over time. A well-designed taxonomy on day one still degrades without governance, because usage patterns and content change faster than any fixed vocabulary anticipates.<\/p>
The most visible symptom of missing governance is synonym sprawl: the same concept tagged multiple slightly different ways by different contributors, none of them technically wrong, all of them fragmenting search for anyone who does not happen to search using the exact variant a given asset was tagged with. Merging those after the fact is far more expensive than preventing them with a controlled vocabulary and a term-approval step in the first place.<\/p>
Governance does not have to mean fully locking down tagging to a fixed list; many DAMs support a hybrid model where users can suggest new terms, but those terms sit in a pending state until someone responsible for the taxonomy reviews and either approves them into the controlled vocabulary or maps them to an existing term.<\/p>","protected":false},"excerpt":{"rendered":"
