  - This time looking at the thumbnail responses in item endpoints
  - According to [the documentation](https://github.com/DSpace/RestContract/blob/main/items.md#main-thumbnail) the API will respond with HTTP 200 if there is a thumbnail, and HTTP 204 if there is no content
  - That means we need to make the request before we can even find out!
+- Tim on DSpace Slack pointed out the DSpace 7 REST API's [projections](https://github.com/DSpace/RestContract/blob/main/projections.md)
+  - This means we can embed resources like thumbnail and owningCollection in the item (and other) requests, for example: https://dspace7test.ilri.org/server/api/discover/search/objects?dsoType=item&embed=thumbnail,owningCollection
+
+## 2023-08-23
+
+- I benchmarked the DSpace 7 REST API with the new embeds and it took four hours and seventeen minutes to get all 106,000 items on DSpace 7 Test
+  - So this is much slower than the results I saw earlier this week, but maybe slightly faster than DSpace 6?
+- Maria from Alliance contacted me to say they have agreed to use UN M.49 regions more strictly in TIP, so they want to replace our non-standard "Latin America" region with "Latin America and the Caribbean", "Caribbean" and "Americas" on all Alliance outputs
+  - I exported their community on CGSpace and fixed the metadata in OpenRefine
+- I tried to run `dspace cleanup -v` on CGSpace, but got this error:
+
+```
+Caused by: org.postgresql.util.PSQLException: ERROR: update or delete on table "bitstream" violates foreign key constraint "bundle_primary_bitstream_id_fkey" on table "bundle"
+  Detail: Key (uuid)=(61bff7da-c8e3-420f-841c-ec5e8238d716) is still referenced from table "bundle".
+```
+
+- The solution, as always, is to delete those IDs manually in PostgreSQL:
+
+```
+$ psql -d dspace -c "UPDATE bundle SET primary_bitstream_id=NULL WHERE primary_bitstream_id IN ('61bff7da-c8e3-420f-841c-ec5e8238d716');"
+UPDATE 1
+```
+
+- I also tried to delete all users who haven't logged in since 2017 using the groomer script, but it crashes due to those users still having items or workflows or whatever:
+
+```console
+$ dspace dsrun org.dspace.eperson.Groomer -a -b 08/23/2017 -d
+```
+
+- I see that it is now [possible in DSpace 7 to delete such users](https://github.com/DSpace/DSpace/pull/2229) so we will have to wait
