Labels
A label is a key-value pair used for logical bucket and object labeling.
Note
In Yandex Cloud terminology, we use the label concept to denote logical resource labeling. However, as Object Storage is compatible with Amazon S3 API, in the AWS CLI commands and API parameters, we use tag, which is a term native to AWS.
