Your first login to Bosch Semantic Stack
At this point we assume you have received a confirmation email from the Bosch Semantic Stack support team containing the tenant ID for your subscription.
The tenant ID is important to know whenever you try to log in as user to one of the user interfaces.
In fact there are three URLs where you can log in:
The Digital Twin Registry UI
The Aspect Model Catalog UI
The Access Management UI
|Compose these URLs by replacing "<your-tenant-id>" with the number received via email. Store the URLs in your key vault where you keep the password for your SingleKey ID - as only this user was granted permission to access the tenant’s data.
Take your time for a short, guided tour on the different UIs.
The Digital Twin Registry hosts the digital twins of your assets on a cloud infrastructure. You will be able to manage the digital twins registered for your tenant.

Working through the getting started guide you might not really get in touch with the Aspect Model Catalog.
However, in case you start creating own Aspect Models and want to add them to the Aspect Model Catalog, here some tips:
The namespace in which you create the Aspect Model needs to be whitelisted for your tenant.
For your "free access" environment, the default namespace would be something like
com.bosch-semantic-stack.sandbox123. To see the exact number assigned to your tenant, navigate the UI as explained at Aspect Model Catalog > Namespaces.
The Aspect Model Editor is open source software and can be downloaded at
The Access Management UI hosts information about the users and technical clients as well as the roles granted to them.
You will be able to add and delete users and technical clients for your tenant. By assigning them to the existing roles you can decide who will be able to read or edit digital twins and Aspect Models for your tenant.
You will learn how to continue at Add a module to your tenant.
