The issue is that both client and media player would have to agree. 
Given that clients have been written to assume that xesam: ones would be 
used, and media players have been written using only xesam: entries, in 
reality new implementations or clients would have to always use the 
xesam: ones.

What we could do is take future additions from nepomuk; so we stick with 
the xesam ones we already have, and we can add nao:, nie: or mpris: 
entries.  The main thing is that 
http://freedesktop.org/wiki/Specifications/mpris-spec/metadata contains 
a canonical list of entries (although media players can, of course, add 
extra ones to their own namespace that some clients might want to make 
use of).
