Importing and round-tripping RDF in Drupal

We need to import arbritary catalogues (spreadsheets) into RDFable Drupal nodes.
We suggest the following as a way forward: before implementing this, we want to see if this would be useful to the broader Drupal RDF community, and whether it is compatible with other existing proposals:
