OK, a couple comments on your second:
I agree with everything in this diagram *except* the box labelled
"multiple
tokens and types". I'm still unclear on what this thing is, and what
sorts
of properties it would have. However, if it represents what I think it reprersents, then I would hang it off the "Individual" class.
It means that in a single Occurrence you can take a picture, record, a sound, and collect several specimens if you want. You can't hang if off of the Individual class if you come back a year later and do it again.
OK, I'll have to digest this a bit more. Got a plane ride coming up, which gives me a few hours of think-time. Perhaps my real problem is that I don't think that collected specimens should be treated the same way that images are (i.e., "tokens").
Some people actually do that kind of thing (me, whale people, bird people).
And so do I.
If you want to keep Darwin Core as the "one specimen-one time" club that it was when it started, then forget about the Individual class.
That's absolutely *NOT* my intention, and my preferred scope of Individual allows MORE flexibility on this; not less.
