Working now -- thanks! Nico
P.s.: I feel quite strongly (as some of you know) that we have some work left here to do. Very briefly [1]:
- taxon, (pl. taxa), n.
- A taxonomic unit, whether named or not: i.e. a population, or group of populations of organisms which are usually inferred to be phylogenetically related and which have characters in common which differentiate (q.v.) the unit (e.g. a geographic population, a genus, a family, an order) from other such units. A taxon encompasses all included taxa of lower rank (q.v.) and individual organisms.
.. is closer to using "Taxon" in the sense of "referent" in the triangle.
I believe (but haven't worked it out, to my own satisfaction even) that this is partly an outcome of the Codes initially regulating name usages in contexts where each publication is a static, finite, one-time event; whereas DwC has evolved to succeed in a rather more expansive, computationally networked communication environment. In addition, the Codes are written by and for our own human cognitive strengths (why else would one care that much about conserved, prioritized, typified names anyway; my computer can handle genome-length name strings for each voucher [but my brain can't]), and we are transitioning into a realm where computational powers can be applied for the purpose of identifying and linking taxonomy's products (but still want/need taxonomic names too).
All for now, though I hope that some of you will at least agree that we have work left to properly position the DwC and ICZN senses of "taxon" in the context of evolving, TDWG mediated communication contexts and needs. Both the taxonomic name <=> taxon (as natural entity) and taxonomic name <=> taxon (as proposed taxonomic theory) linkages can't actually do all the work that the triangle would seem to demand from us.
Cheers, Nico
