When working with big data, it can be very helpful to have access to comprehensive field-level descriptions.
The following steps demonstrate how to add description to a column of a dataset, as a
'comment'. We are using the column iso_cc
(the ISO-compliant country code) in
the dataset World Life Expectancy [data source
samples.world_life_expectancy
].
On the main navigation bar, click Data.
The Data view appears, open on the Datasets tab.
In the Datasets area, select
World Life Expectancy
(samples.world_life_expectancy)
.
In the Dataset Detail menu, select Fields.
In the Fields interface, select Edit Field.
Under Dimensions, find the field iso_cc
, and
click the (down arrow) icon on the
right.
From the menu, select Edit Fields.
The Edit Field Parameters window modal appears.
Under Field Comment, add the following text:
ISO 3166 Country Code Standard, Numeric, described in http://www.iso.org/iso/country_codes. Mappings are at https://www.iso.org/obp/ui/#search.
Click Apply.
Under Dataset: World Life Expectancy, click Save.
Click Show Comments. Notice that
the comment appears with the field iso-cc
.
To hide column comments, click Hide Comments.
