Well, getting those attributes to be in the acquisition namespace 
before indexing still takes some tricky coding, but it's an interesting
observation at least. In addition it would be tricky if you don't have
the attributes anywhere but instead want some method to be called,
something like:

   getMetadataService().getMetadataValue('mymetadataset', 'short_title')

upon indexing.
