So, back on the old XMP tack. The simple vision from the XMP spec is that XMP packets are embedded in media files and transported along with them - and as such are relatively self-contained units, see Fig 1.
Fig. 1 - Media files with fully encapsulated descriptions.
But this is too simple. Some preliminary considerations lead us to to see why we might want to reference additional (i.e. external) sources of metadata from the original packet:

Which reminds me of an issue that has periodically been raised here at Crossref- should we be doing something to try and provide a service for reliably citing more ephemeral content such as blogs, wikis, etc.?

Now, assuming XMP is a good idea - and I think on balance it is (as blogged earlier), why are we not seeing any metadata published in scholarly media files? The only drawbacks that occur to me are:
Hard to write - it’s too damn difficult, no tools support, etc.
Hard to model - rigid, “simple” XMP data model, both complicates and constrains the RDF data model
