Access to Memory (AtoM)

When exporting a SKOS hierarchy, don't include a <broader> term for the selected term, as only the descendents of the selected term are exported. This effectively makes the selected term the top-level term in the exported thesauri.

On import, ignore any <broader> tags that link to a Concept that is not explicitly defined (as a separate <Concept>) in the import file.

However, when using the “Import SKOS” link for term “foo”, any Concepts in the import file that have no valid <broader> (including <broader> tags with no matching <Concept>) should be made children of the selected term “foo”.

i.e. Starting with the following source thesauri:

Birds
|-Waterfowl
| |-Ducks
| |-Geese
| |-Swans
|-Penguins
|-Raptors
  |-Hawks
  | |-Red-tailed hawk
  | |-Northern goshawk 
  |-Eagles
  | |-Bald eagle
  |-Falcons

If export is done at the “Raptor” level, then Raptors should have no <broader> term in the exported SKOS XML file.

If the user then selects the “Birds of prey” term in the target system, and clicks the “Import” button and imports the SKOS XML file created above, the final thesauri should be (assuming there are no existing children of “Birds of prey” existent):

Birds of Prey
|-Raptors
  |-Hawks
  | |-Red-tailed hawk
  | |-Northern goshawk 
  |-Eagles
  | |-Bald eagle
  |-Falcons
