	// The optional metadata that you apply to the dataset group to help you categorize

	// 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.
