AWS Identity and Access Management
API Reference (API Version 2010-05-08)

Tag

A structure that represents user-provided metadata that can be associated with a resource such as an IAM user or role. For more information about tagging, see Tagging IAM Identities in the IAM User Guide.

Contents

Key

The key name that can be used to look up or retrieve the associated value. For example, Department or Cost Center are common choices.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [\p{L}\p{Z}\p{N}_.:/=+\-@]+

Required: Yes

Value

The value associated with this tag. For example, tags with a key name of Department could have values such as Human Resources, Accounting, and Support. Tags with a key name of Cost Center might have values that consist of the number associated with the different cost centers in your company. Typically, many resources have tags with the same key name but with different values.

Note

AWS always interprets the tag Value as a single string. If you need to store an array, you can store comma-separated values in the string. However, you must interpret the value in your code.
