Multimedia

I will first qualify what I am about to say by saying that as I am new
to the group, I am still trying to get an understanding of what
technology level is discussed and the kind of topics that is considered.
I have been thinking about some of the multi-media discussions and had
some thoughts.
 
Is it not possible that we could (and there maybe is) use some meta
description (such as RDF) to describe the multi-media? This could then
describe what is at each part of the image and could be reads by a
screen reader to give a description of the information. It would also be
able to give some content which would be important for financial charts
etc.
 
I guess for just now it would require that page creators enter some Meta
information although I see no reason why this can't be part of tools as
it is the next "thing" of graphics anyway. Vector graphics using XLM has
had much work done on it and this could be extended to support
accessibility (and maybe already hs???).
