Changed the db structure:
Changed the db structure:

"content" is gone. It's all "representation". Ideally a trigger will extract "link" and "category"

Adjusted "link" and "category" to reference "identity" and "representation"

Interaction changed:
  - mime_type replaced by rel_type

Usage:

- On requesting a uri with representation
  - rel-type is set to "self"
  
- On requesting a uri in a "link"
  - rel-type is set to rel value
  
- Interaction is scanned with subject = openid, object = representation.identity (not link href), rel_type = see above
