[Taxacom] progress on globalnames.org

Hi Michael,
Yes, I am not saying that the other levels are not important. I think what I
am proposing still connect to the higher levels.

The particular genus something is put into is a statement about where it
fits in the tree of life. Workers can
differ on the taxonomic placement of a particular species concept, but agree
that they are talking about the same
species concept.

Something also needs to be done about how we represent clades, any takers?

In this example the clades have remained the same, it is just that *
Ochlerotatus* was moved from a subgenus
to a genus. (some accept this, others do not)

Yes, there is a difference of opinion on whether species are different than
the other clades. I think they are.

One simple reason is that members of a species are pretty good at
recognizing each other.

The issue of "find ability" would be solved if we had semantic identifiers
on those pages that would allow you
to do a search for pages that contain information about the genus
"Ochlerotatus".

The identifier  would make it clear that by the string "Ochlerotatus" you
mean a genus.

That specific genus could also have it's own uri hidden in each page that
would serve a similar purpose.

This problem may go away if more people start marking up their web pages
with semantic identifiers.
Google just announced they are going to be supporting this, but they do not
yet have an identifier
for "genus" or "Ochlerotatus"
