That's a very good point. Certainly sculpture (and some other artforms 
that have tactile elements) can be appreciated by people regardless of 
visual impairment.

Rather than taking Sculpture out of VisualArtwork, would there be any 
way to incorporate the "accessMode" property from the proposed 
Accessibility schema type (http://www.w3.org/wiki/WebSchemas/Accessibility)?

E.g. within HTML for a sculpture marked up as VisualArtwork the 
following properties could be added:

<meta itemprop="accessMode" content="visual"/>
<meta itemprop="accessMode" content="tactile"/>


With regards to your point (3):

An edition when related to fine art printmaking (and other fine arts) is 
different to an edition of a journal, comic etc.

For fine art prints only a limited number of prints are taken from any 
plate (or woodblock, silkscreen screen, etc). After this the plate is 
usually destroyed or deliberately damaged to prevent any further prints 
being taken. The same can also apply to photographs, with a number of 
prints being produced before the negative is destroyed or deliberately 
damaged by the photographer.

So if 20 prints were produced from a plate before its destruction then 
you would talk about an edition of 20. (More info: 
http://en.wikipedia.org/wiki/Edition).

I couldn't find any good cross reference in FRBR, but the Getty 
Categories for the Description of Works of Art (CDWA) uses the term 
"Edition size" - see 
http://www.getty.edu/research/publications/electronic_publications/cdwa/6edition.html#RTFToC4 


To avoid confusion with the edition of a book, journal, etc we could 
change the property name for the VisualArtwork type to editionSize to 
match the CDWA term?

Paul
