A method and system are described for generating consolidation groups. An example method includes obtaining a plurality of data type indicators of data types, wherein each data type indicator is associated with a hierarchical subtype of the data type; generating a first subtype indicator of a first hierarchical subtype associated with a first data type indicator in a first hierarchical subtype relationship; generating a first parent list including one or more representations of one or more of the data types associated with the first hierarchical subtype; generating a second subtype indicator of a second hierarchical subtype associated with a second data type indicator in a second hierarchical subtype relationship; generating a second parent list including a representation of one of the plurality of data types associated with the second hierarchical subtype; and generating a first consolidation group based on combining the first subtype indicator with the second subtype indicator.
