</style>I can't help but feel we are getting into a much more complicated area of biodiversity ( or any observation oriented field for that matter ) and
that there must be other ontologies or models that we could follow or reuse.<br>
Our strength at TDWG is obviously the more biodiversity specific details such as taxonomy, invasiveness, etc.<br>
I might have an investigation of possible models to reuse - unless someone has already done this and has a suggestion.<br>

I see dwc:establishmentMeans as being very clearly a property of "Individual<br>
At Place" (again, scoping "Individual" up to at least population). The<br>
closest thing we have to that in the diagram1 is Occurrence. The only hitch<br>
is that Occurrence isn't exactly "Individual At Place", so much as<br>
"Individual At Event[=Place+Time]" Some people have suggected that<br>
dwc:establishmentMeans is a function of Time as well as Place, in which case<br>
it is very clearly (to me) a property of Occurrence.<br>

Well, I also feel pretty good about most of that diagram, but I'm<br>
still struggling with the whole "token" thing. I feel the need to discuss<br>
basisOfRecord=LivingSpecimen which is the most complicated case and is also<br>
related to the previous discussion about dwc:establishmentMeans as well as<br>
my proposal to move it to the proposed Individual class. It is also related<br>
to another issue that I haven't broached here but which is discussed in my<br>
paper - "Occurrences" that aren't directly derived from an individual. I'm<br>
beginning to think that part of what I wrote there (in the paper) was wrong,<br>
but I'm not sure what the alternative is. That issue will probably come up<br>
if I comment about what Cam wrote in his email. So there may be more to<br>
hash out, but I can't handle it today because I've got too many other things<br>
to do. I've been mentally composing what I hope is a lucid presentation,<br>
but it hasn't hit the keyboard yet.<br>

I have to say, this has been about the most productive (if<br>
volumunous)<br>
list-discussion I've had in...well...maybe ever. It seems<br>
we've both been<br>
equally persuasive, and equally willing to concede. How<br>
rare that happens<br>
in an internet forum! I'm not sure there's anything left<br>
that we disagee<br>
about. If the "diagram1" seems to resonate with everyone as<br>
the most<br>
"normalized" ER diagram we'll likely ever need, and if we<br>
can somehow<br>
accommodate flexibility in RDF for collapsing attributes to<br>
different<br>
classes (but only from the "one" side to the "many" side) --<br>
then we might<br>
have achived the elusive Holy Grail of biodiversity<br>
informatics: true<br>
consensus.<br>
<br>
<br>
<br>
Thanks for your great feedback and for challenging<br>
my statements. I need<br>
<br>
<br>
that!<br>
<br>
Likewise! <br>
<br>
Aloha,<br>
