The way I see it, is that the definition of the data interchange format [1] is part of the API and therefore important. 

If we define a flexible format (like JSON) we could define type-value pairs or an array thereof which defines what you get (preferably in a simple way). It could solve the granularity problem i.e. "dc:rights vs. xmpDM:copyright" by informing what attribute is referred e.g. [Disney,dc:rights] [Walt Disney Company ,xmpDM:copyright].  

We could define what a valid array should look like:
[(value, attribute), (value, attribute),..., (value, attribute)]

- and valid values for "value" and "attribute" in BNF for example.

The ontology could then perhaps define the levels of granularity e.g. (from top to bottom) DC -> EXIF -> XMP being the order of the elements in the array, similar to the schema of preference defined by the Metadata Working Group.

Just some thoughts to get the discussion going...
