Not sure what you mean by "temporal attribute" as all attributes and their values are stored in the DB in similar fashion. The advantage of attributes in Id Store config is that you simply refer with attribute name trough your config and not having to worry about to what column/table something is stored.
You can find the all the attributes in the "usual" idm-views, idmv_value_basic and idmv_vallink_basic.
