This release contains updates to the HANCESTRO representation of ethnicity. It includes 2 new classes that live alongside the old ancestry category:
ethnicity category (HANCESTRO:0601)geographic category (HANCESTRO:0602)
The geographic category is a convenience class that groups all ancestry-related descriptors that pertain specifically to geographic regions. The ethnicity category is also a convenience class, grouping any descriptors related to religious, cultural, tribal or other social concepts. This latter category is still a work in progress and we would welcome feedback and input in this area.
In order to correctly represent geographic descriptors, we also modified the ancestry hierarchy in terms of the relationships between larger ancestry groups related to geography, and non-geographic subgroups. These are now related via axioms other than direct parent-child relationships. For example, we no longer assert that Han Chinese is_a Chinese. This has been changed to Han Chinese partially_overlaps_with some Chinese.
