Key-Value Pairs Explained key-value-pairs-explained

Defines and describes standard and serialized key-value pairs.

A key-value pair consists of two related data elements: A key, which is a constant that defines the data set (e.g., gender, color, price), and a value, which is a variable that belongs to the set (e.g., male/female, green, 100). Fully formed, a key-value pair could look like these:

Destinations accept key-value data in standard or serialized format. Standard formatting organizes data into separate key-value pairs. Each key is stated explicitly, even when used again to define a different value. By contrast, serialized formatting condenses multiple values into one set defined by a single key. Also, in a serialized pair, a special indicator is used to separate the values within the key-value set. Finally, standard and serialized key-values can contain single or multiple values. The following table provides examples of standard and serial key-value formats.

When working with serialized data, you must specify the characters that separate values within and between the key-value pairs. Elements in key-value pairs are defined as follows:
