Tag Types

Tag functions have been upgraded on the platform. After the upgrade, a tag consists of a key and a value. Keys and values comply with the following rules:
  • For the tags created after the upgrade, all characters in tags are automatically used as a key, and the value is empty.
  • For the tags that have been created before the upgrade:
    • If no period (.) is used in tags, all characters in tags are used as a key, and the value is empty.
    • If periods (.) are used in tags, the characters before the first period are used as a key and the characters after the first period are used as a value.

After the tag function upgrade, tag management APIs are classified as the APIs for 1D tags and the APIs for 2D tags.

  • A 1D tag contains a string. All APIs for 1D tags are native OpenStack APIs. For details, see this section.
  • A 2D tag consists of a key and a value. All APIs for 2D tags are ECS APIs. For details, see Tag Management.
  • You are advised to use the APIs of the same type to add, delete, modify, or query tags.
  • You are advised to use 2D tags.
