Re: [VOC] Comments on the current version of the vocabulary

I agree that the "usable screen size" can be hard to measure and that  
a lot of factors can modify the result, especially if you think of  
scrollbars that appear only when needed.

I think that there's a mistake in your definition of which WURFL- 
capabilities are in the Browser scope or in the DC. In theory they  
are ALL part of the DC. For example you write the XHTML Basic support  
is a browser "feature", but that the preferred markup is part of the  
DC. I think that we should limit our scope to what is meaningful for  
the device and the browser and leave the DC to other groups or other  
initiatives. All of the properties that you listed are a property of  
the browser first and later of the DC. The browser might support  
XHTML Basic. A transcoding proxy might support XHTML Basic and  
convert it into WML 1.0 because your browser only supports WML 1.0.  
 From a server perspective you might never know it.

For the purpose of the Vocabulary we should limit ourselves to what  
is meaningful for the device. The DC, in fact, is built  on top of  
what the device (and OS and browser and network connection) can do.  
The full DC is a morphing beast that you can hardly manage as things  
are today.

I see a few options here (in no particular order):
a) we think "Usable screen size" is not meaningful for the Core  
Vocabulary, so we drop it as a group
b) we think "Usable screen size" is important, so we work on it
b.1) since it's a complex task, we can refine the definition, clear  
up what we mean
b.2) since it's not entirely in our scope we can define it better and  
limit OUR definition to what we think is in scope
b.3) it's fine as it is
b.4) we are ambitious and want to describe it better and extend its  
meaning in the Core Vocabulary


If you have more options on your mind you can add to the list.
