Thanks Karen, yes this is what we are working on in botany and mycology -
we are using the nomenclators (IPNI and IF) to provide the fundamental
units (names and the objective relationships between them) and then
supporting multiple overlapping - even contradictory - classifications to
be built using these same fundamental units. We are storing enough data on
the relationships which form the taxonomic classifications to do the kind
of assessments that Fred suggests - e.g. to take into account how recently
the hypothesis was published, who published it and where (e.g. was it a
regional treatment or a globally-scoped monograph).
I did quite a general talk about this at the Natural History Museum in
London recently, video here: http://www.youtube.com/watch?v=ynFB6DWCBjc and
slides here: http://www.slideshare.net/nickyn/nicolson-namesbackbonenhm
We've a funded project to rebuild Kew's taxonomic systems in this
environment, and we are working on incorporating the World Checklist system
at the moment, although our communications standard is TCS so we should be
able to import / export data from many different sources.
PS: I'll be at TDWG along with a few people from the Kew team if anybody is
interested in having a closer look.
