The primary reason is that the separation can be useful when describing and formulating decision-procedures for various DL. Description logic was given its current name in the s. This glacier is not yet fully formed. The more operators one includes in a logic and the more complicated the T-box having cycles, allowing non-atomic concepts to include each otherusually the higher the computational complexity is for each of these problems see Description Logic Complexity Navigator for examples.
