Relation dl#conceptual_relation (entity,entity)
  supertype:  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:  conceptual_relation
  subtype:  immediate_relation__immediaterelation (entity,entity)
     subtype:  inherent_in (quality,entity)
     subtype:  q_location__qlocation (quality,region)
        subtype:  has_quale__hasquale__ql (quality,quale)
     subtype:  constituted_by__constitutedby__substance___K__k (entity,entity)
        subtype:  has_member__hasmember (entity,entity)
     subtype:  part (entity,entity)  the subpart may or may not be different from the whole
        subtype:  component (entity,entity)
        subtype:  atomic_part (entity,atom)  an undivisible part
           subtype:  temporary_atomic_part__AtP (entity,atom)
     subtype:  participant__PC (perdurant,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
        subtype:  total_participant__totalparticipant__PC.T (perdurant,endurant)
        subtype:  temporary_total_participant__temporarytotalparticipant__PC.t (perdurant,endurant)
  subtype:  mediated_relation (entity,entity)
     subtype:  present_at__presentat (endurant,time_interval)
     subtype:  q_present_at__qpresentat (physical_quality,time_interval)
     subtype:  happens_at__happensat (perdurant,time_interval)
     subtype:  overlaps (entity,entity)
     subtype:  sibling_part__siblingpart (entity,entity)
     subtype:  proper_part (entity,entity)  the subpart is different from the whole
     subtype:  generic_location__genericlocation (entity,entity)
        subtype:  exact_location__exactlocation (entity,region)
           subtype:  location (entity,region)
              subtype:  physical_location (physical_endurant,physical_region)
                 subtype:  spatial_location__spatiallocation (physical_endurant,space_region)

           subtype:  e_temporal_location (endurant,temporal_region)
           subtype:  p_spatial_location__pspatiallocation (perdurant,space_region)
           subtype:  abstract_location (non-physical_endurant,abstract_region)
           subtype:  depends_on_spatial_location (non-physical_endurant,space_region)
     subtype:  depends_on__dependson (endurant,quality_or_endurant_or_perdurant)
        subtype:  physically_depends_on (endurant,PQ_or_PED_or_PR_or_PD)
        subtype:  descriptively_depends_on__descriptivelydependson (endurant,non-physical_endurant)
     subtype:  host (feature,entity)
