Class PutObjectTaggingCommandProtected

Sets the supplied tag-set to an object that already exists in a bucket.

A tag is a key-value pair. You can associate tags with an object by sending a PUT request against the tagging subresource that is associated with the object. You can retrieve tags by sending a GET request. For more information, see GetObjectTagging.

For tagging-related restrictions related to characters and encodings, see Tag Restrictions. Note that Amazon S3 limits the maximum number of tags to 10 tags per object.

To use this operation, you must have permission to perform the s3:PutObjectTagging action. By default, the bucket owner has this permission and can grant this permission to others.

To put tags of any other version, use the versionId query parameter. You also need permission for the s3:PutObjectVersionTagging action.

For information about the Amazon S3 object tagging feature, see Object Tagging.
