I will take an opportunity to respond to that, but also tie in to where creative hubs can come in and what the vision is.
For us, as you implied, the arts are defined in terms of the professional excellence around the creation, production, and presentation of artistic work. We categorize them in three areas—performing arts, visual arts, and media arts, in principle without getting into every single subsector of the arts. That said, in the performing arts, we're looking at theatre, dance, opera, and live music. In visual arts, it's crafts, photography, sculpture, paintings. Media arts are digital arts and new media arts. Those are the well-established and understood definitions of the arts.
Did I miss any disciplines?
Is there anything else you want to add to that?
