Hi Quentin,
Thank you for your effort in putting forth these welll thought out proposals. At various times I have heard discussions on the inadequecy of establishmentMeans. Your work encapsulates the problem well.
One of the things that helps when proposing to add a Darwin Core term is demonstrating that there is a community that needs it. Can you tell us who has a demonstrated need to share this information? Anyone out there who has this interest is also welcome to share that here to provide evidence of demand from more than one group, project or individual.
Cheers,
John
