[Crm-sig] Issue Visual Item 3D

[Martin Doerr]

Dear All,

I believe that E36 Visual Item should include the surface of statues. 
Therefore,
I propose to change the scope note to:

*NEW:*
This class comprises the intellectual or conceptual aspects of 
recognisable marks*, images and other visual works.*

This class does not intend to describe the idiosyncratic characteristics 
of an individual physical embodiment of a visual item, but the 
underlying prototype. For example, a mark such as the ICOM logo is 
generally considered to be the same logo when used on any number of 
publications. The size, orientation and colour may change, but the logo 
remains uniquely identifiable. The same is true of images that are 
reproduced many times. This means that visual items are independent of 
their physical support.

  The class E36 Visual Item provides a means of identifying and linking 
together instances of E24 Physical Human-Made Thing that carry the same 
visual symbols, marks or images etc. The property /P62 depicts (is 
depicted by)/ between E24 Physical Human-Made Thing and depicted 
subjects (E1 CRM Entity) is a shortcut of the more fully developed path 
from E24 Physical Human-Made Thing through /P65 shows visual item (is 
shown by)/, E36 Visual Item, /P138 represents (has representation)/ to 
E1CRM Entity, which in addition captures the optical features of the 
depiction.

-----

And add the example:

"The surface shape of Auguste Rodin's statue "Le Penseur" [there exist 
more than 20 copies, even of different size]
