Tag naming and usage conventions - AWS Elemental MediaConnect

Tag naming and usage conventions

The following basic naming and usage conventions apply to using tags with AWS Elemental MediaConnect resources:

  • Each resource can have a maximum of 50 tags.

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • The maximum tag key length is 128 Unicode characters in UTF-8.

  • The maximum tag value length is 256 Unicode characters in UTF-8.

  • Allowed characters are letters, numbers, spaces representable in UTF-8, and the following characters: . : + = @ _ / - (hyphen). Amazon EC2 resources allow any characters.

  • Tag keys and values are case sensitive. As a best practice, decide on a strategy for capitalizing tags, and consistently implement that strategy across all resource types. For example, decide whether to use Costcenter, costcenter, or CostCenter, and use the same convention for all tags. Avoid using similar tags with inconsistent case treatment.

  • The aws: prefix is prohibited for tags; it's reserved for AWS use. You can't edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource quota.
