Using the data catalog, you may also provide descriptions on every dataset property to make them easier to understand. This is helpful when a dataset includes codes or abbreviations in the dataset.
To define properties in a dataset, open the edit dataset popover, then scroll to the bottom section. Open the data dictionary builder, then select edit on the property you'd like to define.
Add or paste a definition into the description field. Select done, then save the dataset to apply the changes.
Don't forget, the platform indexes all of this information in the search service, which means you can find datasets based on their property definitions!
