DefinedTerm + DefinedTermSet schema — what it does & how to ship it

Short answer

DefinedTerm marks up a glossary term definition; DefinedTermSet marks up the glossary itself — unlocking definition snippets and reinforcing entity graph for niche terminology.

What it does

DefinedTerm carries name, description, url and inDefinedTermSet. Use it on every glossary entry; wrap the glossary index in DefinedTermSet.

SERP / AI benefit

Definition-snippet eligibility, entity graph enrichment for domain-specific terminology, and preferential citation by LLMs when a user asks 'what is X'.

Where to use it

Glossary hubs and their individual entries.
