Relation dl#conceptual_relation (dl#entity,dl#entity)
  supertype:  pm#relation_playing_a_special_role (pm)  this type permits to categorize relations according to their roles ; this is a traditional but quite subjective way of categorizing relations
  inverse:  dl#conceptual_relation
  subtype:  dl#immediate_relation__immediaterelation (dl#entity,dl#entity)
     subtype:  dl#inherent_in (dl#quality,dl#entity)
     subtype:  dl#q_location__qlocation (dl#quality,dl#region)
        subtype:  dl#has_quale__hasquale__ql (dl#quality,dl#quale)

        subtype:  dl#has_member__hasmember (dl#entity,dl#entity)
     subtype:  dl#part (dl#entity,dl#entity)  the subpart may or may not be different from the whole
        subtype:  dl#component (dl#entity,dl#entity)
        subtype:  dl#atomic_part (dl#entity,dl#atom)  an undivisible part
           subtype:  dl#temporary_atomic_part__AtP (dl#entity,dl#atom)
     subtype:  dl#participant__PC (dl#perdurant,dl#endurant)  the DOLCE predicate PC(x,y,t) means "x participates in y during t" but this relation respects the usual reading conventions: the 1st argument has for participant the 2nd
