A Meta-taxonomy for Museums

For a secret project I’m working on, I need a taxonomy of types of museums (that narrows it done a bit, doesn’t it?)

Because none really seems to exist, I took a stab at one:

History
	General
	Cultural
	Natural History
	Nature Center
	Transportation
		General
		Aviation
		Automobile
		Railway
	Historic House
	Historic Site
	Military
	Maritime
		Military
		General
		
Arts
	Fine Arts
	Decorative Arts
	Modern Arts
	

Science
	General
	Computers
	Aviation (Air / Space)
		Military
		General 
	Planetarium

Specialized
	Medium
		Photography
		Film
	Object-specific (e.g. Victorian Doll Museum)
	Corporate (e.g. Jell-O museum)
	Personal
	Children's

Natural
	Zoo
	Arboretum
	Botanic Garden
	Aquarium


Any comments would be welcome (I expect the taxonomy to sort-of come live as data gets added to said project, but I’d like to have at least a start!
