@balhoff @jmcmurry what prefix for ICD-O? ICD0?

[balhoff]

It's a capital 'O'. Could the prefix be ICD-O or ICD-O-3? I'm not sure how the codes do or don't change across versions.

Is this still an open issue? Somehow it's in the Feb 2024 Mondo Release board.

We still have some work to do to improve ICDO alignments, and we need a better strategy for updating our ICDO x-refs. This issue references a workaround way to import ICDO references from NCIt. We now have documentation and a pipeline that will eventually take us to address this issue again (eventually). Let's close for now and work on it when it surfaces again.
