Dataverse: script to verify WorldMap links are valid

[raprasad]

Dataset metadata will contain links to WorldMap layers.

Verify that the WorldMap links are valid--e.g., that the layers still exist.

Run this check via GeoConnect:

• Get all map layer metadata links via API call
  • Add Dataverse API call to return list of MapLayerMetadata objects. Started in f0cec55.
• Check against WorldMap, delete non-existent links
• Run reverse check. For Layers with DataverseInfo objects, make sure Dataverse still has the file/dataset. Delete the WorldMap DataverseInfo object but not the Layer itself.
  • should rarely happen

Notes

• New API endpoint needed in Dataverse codebase
• Originally geoconnect issue: Dataverse: script to verify WorldMap links are valid geoconnect#12

We discussed this in the Sprint Planning meeting yesterday. We decided on the following approach:

• We'll add an API endpoint to Dataverse
• We'll add a script to run in Geoconnect to verify the mapping in Dataverse (using the new endpoint) and the the endpoint in Worldmap (existing endpoint)
• We'll Update the Geoconnect documentation to inform users what happens when a mapping is deleted
