IMHO, two aspects get lost by using the MGET, MPUT, etc for retrieving 
metadata.

I would argue that sometimes metadata about metadata is required (e.g., 
quality assertions about metadata assertions) .  This is why metadata 
should be a first class citizen (i.e., have its own URI).

Secondly, there is a tremendous amount of metadata which would be 
qualified as opinions (e.g., think of Moody bond ratings).  Furthermore, 
metadata about a resource is often created by third parties (i.e., not 
the owner/publisher of the resource).

These were the reasons Roger Costello and I argued for adding the 
Meta-Location and Meta-About HTTP headers.  Which support those aspects.
