  FAIR metadata is critical to supporting FAIR data overall. Transparency,
community engagement, and flexibility are key aspects of FAIR that apply to
metadata. This paper presents YAMZ (Yet Another Metadata Zoo), a
community-driven vocabulary application that supports FAIR. The history ofYAMZ
and its original features are reviewed, followed by a presentation of recent
innovations and a discussion of how YAMZ supports FAIR principles. The
conclusion identifies next steps and key outputs.
