|This partial tree only displays OID arcs with more than 23 000 descendants to show the heaviest OID arcs (i.e. with the greatest number of child OIDs, grandchild OIDs and so on) in the whole OID tree. (Please note that it is the number of descendants as described in this OID repository, not necessarily the real number of descendants of each OID.)
→ Clicking on an icon like or displays a density tree focused on the associated OID.
Arcs which hold more than 4% of the total number of OIDs are in orange.
