[tdwg-content] biostatus

This draft you mention looks like it is for vernacular names, and other stuff, but not biostatus in particular.  But the same propeties could be applied to biostatus, ie

- taxon concept id
- biostatus origin (indigenous, exotic, etc)
- biostatus occurrence (absent, present, etc)
- date / temporal
- publication / source
- locality / locationId / code / geospatial parameters

hopefully mostly using Dublin Core properties, ISO codes and other standards.

We have a draft Distribution extension that Markus initiated that represents our thoughts in this area.

OK, I think we're in agreement that taxon (concept) attributes could include some kind of summary or assertion about whether its presence in some area is native or otherwise.  As Rich says, that may need further thought to be included in DwC in this round.  I think there is a strong rationale for having the ability to say the native range of taxon X is footprint Y.  Any organism occurrence outside that would characterized (as native, invasive, etc.) by comparison against that footprint.  That means...

The data concept that would best be applied to organism occurrence would be "wasCultivatedOrCaptive" and therefore not representative of viability at the place at that time.  Whether a non-cultivated/captive occurrence is native, invasive, naturalized, or ?? remains a comparison to the (a) distribution of the taxon.

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.
