Not sure if Jerry's post got through to the list - it looked like it bounced. So I am posting again on his behalf...

A lot of this was thought about when we were working on the IAS Profile schema and associated use-cases ... http://wiki.tdwg.org/InvasiveSpecies/
Agreed that 'biostatus' (which is an imprecisely defined trem) is a property of a taxon concept.
In many domains there clearly a need to pass information about the presence/absence and indigenous/endemic/introduced/invasiveness etc, status of a taxon, in a defined geograhical area. Of course this is not primary data relating to specimens or observations, but is an aggregate opinion based on evidence available to the compiler. Open any book on any aspect of biogeography and you will find such statements and polygon boundaries.
It is one of the elements gathered by Species2000. It certainly an implicit or explicit component of regional checklists. Our recently funded NZOR project (http://nzor.org.nz) will compile the first digital catalogue of life for New Zealand and a key requirement dicated by our funders (and biosecurity legislation) is accompanying evidence-based statements of the presence or absence of a taxon (concept) in New Zealand political, economic and biogeographical borders.
Such statements only belongs in DwC in a most abstract extension of DwC relating to passing taxon concept related data, and not primary data on collections/observations.

Absolutely, the invasive species people need to have their input here. Invasive species data is a great use case of biostatus data.
There should be allowance for invasive attributes in the new Darwin Core, considering the invasive species group attempted to extend darwin core previously.
I do believe biostatus applies to Taxon Concepts, not specimens (if that was what you were implying Stan), as you cannot really say that the specimen itself is invasive - it is the concept you have identified it to that can be deemed invasive, surely.
Specimens can provide a "present" biostatus, but not "absent", nor biostatus origin, such as "exotic". So they are a source of biostatus data, but I dont think they are objects that biostatus is strictly attributed to.

I don't know what the current thinking is regarding the invasive species work and the DwC, but what you're asking for, Kevin, seems to me to be a summary judgement about the occurrence (presence) of a species in a geographic region. I think individual organism occurrence records (note I don't use species occurrence) can be tagged with an attribute indicating that the record can be used for distribution analysis (but that may need to be further refined into native, naturalized (=invasive?), and cultivated/captive).
I think the invasive species folks need to weigh in here about their use cases: data they want to analyze about organisms, versus summary statements they want to make about taxa.
My two cents,
-Stan

I was just thinking to that the "locality" type component should be influenced by other geo components within TDWG - ideally it probably should be linked to TDWG regions, dublic core, ISO, or other vocab?
Also, there is probably a time element in this. But I don't think we need to go there. :-)

Makes sense, but need a "second" of the motion to include.

Yes, thats a good start, however, biostatus is a more complicated topic than that, eg whther it is "native" may depend on the region you are looking at - so region data needs to be included, and whether it is present or not also is another important piece of data.
biostatus is also really a name/concept oriented piece of data, not specimen/occurrence. So maybe useful to have as domain (RDF) independent??
So I suggest a "class" fro biostatus that includes: Biostatus (eg Endemic, Indigenous, Exotic) BiostatusOccurrence (eg Present, Absent) BiostatusRegion (eg, New Zealand)
so you could have biostatus about a taxon in NZ like "Aus bus" has biostatus in NZ, Exotic and Present and a more lacalised biostatus for a region of NZ, eg "Aus bus" has biostatus in Canterbury NZ, Exotic and Absent
Make sense?

Hi Kevin,
Not exactly sure what is meant by biostatus given what you have written, but have a look at the term establishmentMeans (http://rs.tdwg.org/dwc/terms/index.htm#establishmentMeans) and see if that is the same or similar.

This is a bit out of the blue, and I haven't had the chance to look into it fully, but...
is there allowance for Biostatus in the new Dariwn Core format?
An imprtant, and common field - ie Biostatus occurrence, locality, and status, eg "Present Indigenous"
