Thanks, Pier
Just for a bit of background - you're assuming these are IRIs, but the DwC-A work was all designed at a time when URNs were common and expectations of resolvability weren't as high as today.
The original design was really just to ensure a globally unique URN was used.
I think the concerns you raise are valid, and especially with the current intent to achieve resolvability for all the w3id.org/... terms.
We do need a URN though, and I understand there isn't an intention to make resolvable terms for these concepts. The rs.gbif.org namespace has been used for this kind of thing in the past, which might be an alternative option to lower expectations.
Thanks,
Tim

Dear TG, Dear Ramona (GSC CIG), Chris, Bill,
In our DwC-MIxS mapping activity, we noted a practice to support the IPT
to generate "picklists" (for drop-down menus etc) by adding extensions
to IRIs.
This was suggested as a means to link the values to keys in
terminology-focused fields.
You can see the link to the "picklists" in the tracker:
https://github.com/tdwg/gbwg/tree/main/dwc-mixs/dwc#vocabularies
An example is available in [1] and looks like:
dc:URI='https://w3id.org/gensc/terms/MIXS:0000005/contigs'
I'm not quite sure about this and would like your input. To me, it seems
like a very strange way to modify an identifier *issued by another
standards group* in order to help a tool generate dropdown menu.
It essential creates a false impression that there's something
standardised on the other end of that IRI that may or may not be the case.
Best,
Pier Luigi
