The concepts are known elements for the platform. Your data is more explicit.
Concepts increase the reusability of your data and link your data to the functionalities of Data Fair such as enrichment.

The dataset edition page allows to select the concepts in the Schema section.

  1. Selected column
  2. Label and description of the column
  3. Key, type and cardinality of the column
  4. Concept associated with the column

Concepts are needed to create of some visualizations.

A concept is unique for a dataset, it can only be attributed once to a dataset. For example, if the Latitude concept is associated with a column of your dataset, it cannot be associated with another column.
