Workspaces
In Structurizr, a workspace is the wrapper for your software architecture model, views, and supplementary documentation. The recommendation is that a workspace contains the model, views, and documentation for a single software system - see Workspaces - Scope for more details.
Unlike most modelling tools, Structurizr separates workspace authoring from workspace rendering via its open JSON data format.
Troubleshooting
See Workspaces - Scope - Troubleshooting if you are seeing error messages like Strict workspace scope validation has been enabled ... Unscoped workspaces are not permitted
