A couple of observations:

- IIUC, the browse view should also contain the following:
<link rel='meta' type='text/xml' href='http://path.to.wiki/index.php?n=Group.Page?action=dc' />
  showing where the DC metadata may be found

- note Pm's careful use of 'normally'; e.g. there is a project here 
  in NZ that will, when it comes to fruition, provide a DC-based 
  window into the entire country's scholarly research output:

  -- make publicly-funded research publicly accessible via the Web

  -- harvest DC metadata on all research outputs that have been 
     deposited in participating institutions' open access digital

  -- expose this harvested DC metadata as a Web Service, enabling
     third party applications, such as a wiki, a learning management
     system, an online library catalogue, or even a word processor, 
     to incorporate live DC data streams, including links to the
     original materials, wherever they may be held

  -- encourage non-aligned researchers, like local historical
     societies, to participate and make their materials available
     to others

  a big dream; a big challenge
