| Description | The Medical Action Ontology (MAxO) provides a structured vocabulary for medical procedures, interventions, therapies, and treatments for disease with an emphasis on rare disease (RD).

Responding to this need, MAxO provides a vocabulary to annotate diseases and phenotypes with recommended treatments and interventions. |
