Workspace
A workspace is where a brand competes: a named set of - the demand space, such as "Website governance" or "UK business banking" - plus the identity brand whose workspace it is.
Every Presence screen is scoped to one workspace, and the identity brand is who its numbers are about. Every subject topic belongs to exactly one workspace and cannot be moved or shared. Topics inside a workspace can optionally be filed in a ; that grouping is not the workspace itself. Each workspace also has its own competitor roster - the brands its screens compare you against - which you curate, helped by suggestions drawn from the names your own answers keep offering.
