The logical data specification methods act on a value of type DM_LogicalDataSpec. Use these methods to modify and to query the logical data specification value.
You can create a value of type DM_LogicalDataSpec from a value of type DM_MiningData by using the data mining method DM_genDataSpec. This sets the logical data specification to default values. You can use the methods described here to modify this logical data specification.
You can also use these methods to create a logical data specification from scratch, to specify taxonomies, and to do other specification tasks.
