Words Matter! Using mutually understandable terminology is vital to humanitarian collaboration.

Taxonomies allow terms to be understood in both human and machine readable ways.

Hierarchical Relationships (indicate that a term has a range of other terms that are broader or narrower in meaning):

Associative Relationships (indicate that a term has a range of other terms that typically relate to it, or participate in it):
