class Aws::ForecastService::Types::Tag
The optional metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
-
Maximum number of tags per resource - 50.
-
For each resource, each tag key must be unique, and each tag key can have only one value.
-
Maximum key length - 128 Unicode characters in UTF-8.
-
Maximum value length - 256 Unicode characters in UTF-8.
-
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
-
Tag
keys and values are case sensitive. -
Do not use `aws:`, `AWS:`, or any upper or lowercase combination of such as a prefix for keys as it is reserved for AWS use. You cannot edit or delete tag keys with this prefix. Values can have this prefix. If a tag value has `aws` as its prefix but the key does not, then Forecast considers it to be a user tag and will count against the limit of 50 tags. Tags with only the key prefix of `aws` do not count against your tags per resource limit.
@note When making an API call, you may pass Tag
data as a hash: { key: "TagKey", # required value: "TagValue", # required }
@!attribute [rw] key
One part of a key-value pair that makes up a tag. A `key` is a general label that acts like a category for more specific tag values. @return [String]
@!attribute [rw] value
The optional part of a key-value pair that makes up a tag. A `value` acts as a descriptor within a tag category (key). @return [String]
