The IsShared property of the Dimension interface indicates whether a dimension object can be shared among multiple MDStore objects.
Boolean
Read-only
DSO sets the IsShared property by reading the Name property of the Dimension object. A dimension that is private to a cube has a name of the form MyCube^MyDim, where MyCube is the cube that contains the dimension. A dimension object that can be shared does not have the cube name as a prefix.
The value of the IsShared dimension of a database property is inherited by the associated cubes (and their partitions, aggregations, and virtual cubes).
