Prior to starting a mapping process, we run a SPARQL query to identify the LDP-NRs that will be processed during the batch. Then, for each LDP-NR:
- A HEAD request is sent to the LDP-NR verifying that the resource exists
- A GET request loads the LDP-NR's current state; A process generates an RDF graph from the LDP-NR contents and...
- A HEAD request checks for the existence of the LDP-RS (this is needed to generate the correct provenance triples)
- A PUT request fully replaces the current state of the LDP-RS.

- A GET request loads the LDP-RSs current state; a process or sequence of processes alters the retrieved graph, and:
