I thought I'd introduce you to an initiative I've started to make changes to the Darwin Core Standard. This seems to be relevant to the Task Group and something we could point to as a concrete outcome.

For a long time I have been bothered by the definition and suggested vocabulary for the establishmentMeans field in Darwin Core (http://rs.tdwg.org/dwc/terms/). It doesn't seem fit for purpose and conflates various concepts. For this reason I've drafted a proposal for the TDWG organisation to change Darwin Core. This involved adding a new term "origin"; changing the definition of occurenceStatus and changing the controlled vocabulary of establishmentMeans.   You can read the proposal on GitHub (https://github.com/qgroom/DwC_Proposal.git), but I've also attached a version here. 

I really welcome your comments and I'd be happy if you want to co-propose it with me.

Regards

Quentin
