Schema 0.8.3

[Tony Linde]

Ray,

I started making some comments on the schema 0.8.2 which gradually got more
drastic, so I ended up generating my own 0.8.3 version. The comments are as
below.

Core change is to move ManagedResource stuff up into Resource, fold stuff
like facility, instrument etc into Relationships, add descriptor into
relationships etc. 

Hope it all makes sense.

Cheers,
Tony.

  drop Curation (moved to vr:ResourceType)

  ? Subject should be called Keyword
  ** if above accepted, move Keyword & ContentLevel to Resource
  **  & derive everything from Resource
