[mythtv] MythMusic: MetaLibrarian RFC

[thor]

 In the abstract, it's a fine idea. We don't all use parochial code to do host 
name resolution; we all ask DNS to resolve host names for us.  Why not a 
similar service for audio metadata, even if only at the local level.

 But describing an idealized service is one thing. Building it is quite 
another. Getting a non-trivial percentage of applications to even be aware of 
its existence is a still much larger hurdle. 

 If you want to get anywhere close to a path that might lead to wide 
acceptance of your idea, you will need to make it work with current 
(unmodified) software. That means, to the extent possible, pushing metadata 
back into the mp3's themselves (ie. writing tags that other software can 
read).

 So ... uhm ... for mythmusic, where exactly are we on 2.3 versus 2.4 tags? As 
I understand things, we're now writing tags that almost nothing else can 
understand. Is that accurate? If so, can we improve on that  :-)   ?


btw: DAAP does have rather extensive metadata-description capabilities, but 
in-and-of itself it is just a markup and streaming protocol. It says nothing 
about how that data should be persisted.
