Concept: Meaning

Summary

Summary

In this lesson, we take a look at the Meaning of a column. The meaning gives a “rich” semantic label to the data type. Meanings are automatically detected from the contents of the columns, but you can also define custom meanings. Meanings have high-level definitions such as url, ip address, or country. Each meaning is able to validate a cell value. Therefore each cell can be valid or invalid for a given meaning.
