- I noticed the licenses were missing from Nilam's original file so I found a way to check [Dataverse's API for a persistent identifier](https://guides.dataverse.org/en/latest/api/native-api.html#export-metadata-of-a-dataset-in-various-formats)
- We have both Handles and DOIs for these datasets, both from Harvard's Dataverse

- I used this GREL in OpenRefine to create a new column based on URLs using the DOI (uppercasing the DOI for Dataverse):
- Spent some time checking the remaining 3312 IFPRI 2016–2019 migration set for duplicates on CGSpace
- There seem to be about 50 exact matches of title, type, and issue date
## 2024-06-20
- Finalize merging and uploading metadata for 48 duplicates from the IFPRI 2016–2019 migration set
- Heavy load on both CGSpace and DSpace 7 Test this afternoon
- Took me a while to figure out it was due to someone / something hammering `/search` for a bunch of facets
- The `pm2 logs` command was more useful than the nginx logs to see the requests at least, for example:
```

```
- Still difficult to find the client, because the logs are all [coming from Angular's user agent](https://github.com/DSpace/dspace-angular/issues/2902) and IP
- I changed the nginx logging to use the `X-Forwarded-For` header, as the default `combined` log format uses `$remote_addr` by default, which is only accurate if the request doesn't come from Angular (ie directly to the API)
- From what I can see now the IPs are all coming from Huawei Cloud and Tencent
- The ASNs are AS136907 (Huawei) and AS132203 (Tencent)
- For now I will just add those to the list of bot networks
## 2024-06-21
- Update the nginx logging to use [nginx's `real_ip` module](http://nginx.org/en/docs/http/ngx_http_realip_module.html) to log the correct client IP
- I think this means we will start sending 'bot' to the Angular / Express frontend because bot IPs will be properly classified now...
- I will have to re-work or at least re-think that nginx configuration for requests going to the frontend because the proposed fix in https://github.com/DSpace/dspace-angular/issues/2902 is to pass on the client's user-agent
