Deleting Object Tags (SDK for Java)

Function

This API is used to delete tags of an object. For more information about object tags, see Adding Tags to an Object.

If there is no object version ID (indicated by versionId) contained in the request, you must have the DeleteObjectTagging permission. If you specify a version ID in a request, make sure that you have the DeleteObjectTagging and DeleteObjectVersionTagging permissions. By default, only the object owner can perform this operation. The object owner can grant this permission to others by using a bucket policy or a user policy.

OBS deletes tags from the current object version by default. You can use the versionId parameter to delete tags from any other version. If the version is a delete marker, OBS returns 404 Not Found.

Restrictions

This API is not available for parallel file systems.
