[tdwg-humboldt] Humboldt Task Group Meeting Wed 16 November 2022, 08:00 EST

[Zachary Kachian]

Hi Rob,

My understanding is that, in our case, completeness is not reported by the
inventory team in their final report. The descriptions of completeness from
the previous email are how the ecologists understand the term and how
they *would
*calculate it, but I don't believe that they do. Happy to discuss this more
if it is helpful.

Best,
Zach
