In order to separate things from different solution spaces from each other, they are required to be created in a specific namespace. This namespace needs to be provided on each request as a :-separated prefix of the thing ID.
Each thing ID has the form <namespace>:<thing-name>.

  • The namespace must conform to the reverse domain name notation:
    • must start with a lower- or uppercase character from a-z
    • can use dots (.) to separate characters
    • a dot (.) must be followed by a lower- or uppercase character from a-z
    • numbers can be used
    • underscore can be used
  • The namespace is separated by a mandatory colon (:) from the rest of the thing ID.

Examples for a valid thing ID:


The same concept applies to namespaces for other entities:
e.g. policy.

The user interface Manage your namespace might be helpful in case you need to set or change your “default” namespace.
