What are Ontologies?

Ontologies detail the structure of data labels and how these labels relate to each other hierarchically. They are a way to systematically define and categorize the specific scope of datasets, which enforce dataset standards and encourage clarity.

Managing Ontologies

Nexus supports ontologies at various levels illustrated in the table below.
