Thank you both for working this out and explaining the details.

I do think it is less confusing to use the GBIF namespace for URNs, rather
than append the GSC URIs. Citing the MIxS URI then allows people to find
the original term.

Tim, would it help if we assigned URIs to the values in the CVs? That is
our eventual plan.
