Object Tags

US3 supports using tags to classify objects (Objects) in storage spaces (Buckets). Users can set lifecycle rules for objects with the same tag. For lifecycle-related information, please visit Lifecycle. Currently, object tags are supported in Vietnam and Brazil. For other regions, please contact technical support if needed.

Instructions for Use

Object tags use a set of key-value pairs (Key-Value) to mark objects. Users can add tags when uploading objects or add tags to existing objects.

• A single object can be set with a maximum of 10 tags. Keys cannot be duplicated, and neither keys nor values can be empty.

• Each key can be up to 128 characters in length, and each value can be up to 256 characters in length.

• Keys and values support uppercase and lowercase letters, numbers, spaces, and special characters: + - = . _ : / @.

Note: When setting tags via HTTP Header and the tags contain any special characters, the keys and values of the tags need to be URL-encoded.
