Tagging_CategoryModel_Cardinality
The CategoryModel.Cardinality enumerated type defines the number of tags in a category that can be assigned to an object.
SINGLE : An object can only be assigned one of the tags in this category. For example, if a category is "Operating System", then different tags of this category would be "Windows", "Linux", and so on. In this case a VM object can be assigned only one of these tags and hence the cardinality of the associated category here is single.
MULTIPLE : An object can be assigned several of the tags in this category. For example, if a category is "Server", then different tags of this category would be "AppServer", "DatabaseServer" and so on. In this case a VM object can be assigned more than one of the above tags and hence the cardinality of the associated category here is multiple.
