 - Export CGSpace to check for missing Initiative collection mappings

+- Start a harvest on AReS
+
+## 2023-08-21
+
+- Experiment with the DSpace 7 REST API
+  - I wrote a Python script to benchmark harvesting all 100,000+ items using the `/api/discover/search/objects` endpoint 100 items at a time
+  - I was able to harvest the entire 106,000 items in fifty-two minutes, which seems slow, but that's about ten times faster than with the legacy REST API...
+  - Still, I need to benchmark a bit more, as the item response doesn't include collection mappings or thumbnails
+- Reading the [API docs](https://github.com/DSpace/RestContract/blob/main/README.md#etags--conditional-headers) it seems that we should be able to use the standard `If-Modified-Since` header for some endpoints
+  - I tried it on the `/api/discover/search/objects` and `/api/core/items` endpoints, but apparently those don't support this header because I don't see a `Last-Modified` header in the response
+  - According to the docs, it means that these endpoints indeed don't support it...
+
+## 2023-08-22
+
+- I was experimenting with the DSpace 7 REST API again
+  - 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!
