Hey Thad,

Sorry it took me a bit to reply because of Wikimania.
https://www.wikidata.org/wiki/Q1931388 does have a link for the NCI
Thesaurus ID for me. The reason for it not being in the external
identifier section is that it has datatype string and not external
identifier like the others in the external identifier section. It can
be converted if there is rough consensus to do so.
Are there still other issues that I didn't answer?


Cheers
Lydia
