Namespaces

A namespace is the repository for entities (for example, models) created using the AWS IoT Things Graph Data Modeling (TDM) language. These entities are associated with a specific account. The namespace is part of the URN for each entity.

When you upload TDM entities for the first time, AWS IoT Things Graph creates a namespace for you. The namespace consists of your AWS Region, your account ID, and a fixed suffix default. The pattern is REGION/ACCOUNT ID/default. For example, a TDM entity created in the us-west-2 region looks like this: us-west-2/012345678910/default.

You can extend the path under default to organize your entities. For example, you could place your device definitions under default/devices and your property definitions under default/properties.

Currently AWS IoT Things Graph supports only one namespace per account. TDM entities that are stored in a namespace are Properties, States, Events, Actions, Capabilities, Mappings, Devices, and Services.

There are two kinds of namespaces: public and private. The namespace associated with your account is private. You create and upload your own entity models inside this namespace. The public namespace is maintained by AWS and contains the entity definitions that all accounts can access. Private namespaces track the public namespace, and you can synchronize your private namespace with a specific version of the public namespace.
