Hi! I wonder, why vivo:Committee as well as foaf:Group doesn't have the Affiliation property group? Both of the classes can be a kind of organization and they can also be affiliated as sub-organization to other ones. It would be also very usefull, if one could affiliate a committee to an event or even event series, as there are many conference series, which have steering committees, organizing and convening these events.
We would propose as a common solution, that foaf:Group and vivo:Committee as its sub-class should also should have properties which are typical for other kinds of organizations.
What is your opinion on that point?
Thank you for your help in advance.
