Tag
Metadata that is associated with AWS resources. In particular, a name-value pair that
      can be associated with an AWS Cloud9 development environment. There are two types of tags:
        user tags and system tags. A user tag is created
      by the user. A system tag is automatically created by AWS services. A system tag is prefixed
      with "aws:" and cannot be modified by the user.
