Overview

The object tagging feature is designed to help you group and manage objects in your bucket. You can add key-value pairs for your object as its identifier. An object tag is made up of a tagKey, =, and tagValue (for example, group = IT). You can set, query, and delete tags for a specified object.

Note：

Object tagging is a billable service. For detailed pricing, please see Product Pricing.

Keep the following restrictions in mind when you use object tagging:

• You can add up to 10 different tags for one object.
• A tag key cannot start with qcs:, project, or any other system reserved characters.
• Tag keys and tag values are case-sensitive. Both of them can be 1-127 UTF-8 characters in length, containing letters, spaces, digits, and special characters +, -, =, ., _, :, /, @.

For more restrictions, please see Object Tagging Overview.
