@qingyao do you want PRs or issues or shall we move the mappings to this repo?

E.g.

icdot-C57.9 | other female genital | UBERON:3011048 | genital system | 197.726222755931 |   |  

the female-specific subclass is more accurate. Though due to the 'other' we would make this skos:close not exact

Thanks! Yes, you can move the mappings to this repo.
