Follow the guidance provided in https://knowledge.exlibrisgroup.com/Primo/Community_Knowledge/How_to_%E2%80%93_Force_records_from_external_data_sources_to_be_updated_or_deleted_in_Primo_VE for building an XML file that looks like this:

<ListRecords>
  <record>
    <header status="deleted">
      <identifier>oai:repositoryx.grinnell.edu:grinnell_16184</identifier>
    </header>
  </record>
  <record>
    <header status="deleted">
      <identifier>oai:repositoryx.grinnell.edu:grinnell_16185</identifier>
    </header>
  </record>
</ListRecords>

The above .xml file will remove TWO Primo VE records created from import of OAI exported from Digital.Grinnell. It will do so for grinnell:16184 and grinnell:16185, a pair of objects with similar titles that got de-duped into https://grinnell.primo.exlibrisgroup.com/permalink/01GCL_INST/1prvshj/alma991011546867904641.

Finding the DIP/OAI Identifiers

The OAI identifiers for these objects were determined by appending &showPnx=true to the end of the object’s Primo permalink, so https://grinnell.primo.exlibrisgroup.com/permalink/01GCL_INST/1prvshj/alma991011546867904641&showPnx=true which yields a wealth of data including these two lines:

    "ilsApiId" : "oai:repositoryx.grinnell.edu:grinnell_16185",
    "ilsApiId" : "oai:repositoryx.grinnell.edu:grinnell_16184",

Note that the aforementioned XML syntax is much easier to create in-bulk, and it’s perfectly acceptable:

<ListRecords>
<record><header status='deleted'><identifier>oai:repositoryx.grinnell.edu:grinnell_16184</identifier></header></record>
<record><header status='deleted'><identifier>oai:repositoryx.grinnell.edu:grinnell_16185</identifier></header></record>
</ListRecords>

Final Outcome

After running the file shown above, I believe the old OAI records did disappear from Primo after a few minutes time. During the “purge” Primo did display a placeholder “inkingParameter1” link to https://digital.grinnell.edu/islandora/object/ for the recently removed OAI record. This too is expected to disappear after about 30 to 60 minutes time.

Before and After

Permalink here is https://grinnell.primo.exlibrisgroup.com/permalink/01GCL_INST/1prvshj/alma991011547306404641. This is an object in the Ancient Coins collection and the corresponding DIPs were removed on 8-Nov-2024. The XML file used in this operation was subsequently renamed to remove-DIP-records-Nov-8.xml to make way for the next DIP removal job on November 11.

Yay! The MMS Id and permalink remain unchanged too!

A similar DIP removal job was run on November 11 using the XML file named remove-DIP-records-Nov-11.xml. That file was intended to remove ALL remaining DIP records from collections that migrated to Alma before November 11. That file contained 4301 records to be removed.
