- Start working on CGIAR Library migration
- We decided to use AIP export to preserve the hierarchies and handles of communities and collections
- When ingesting some collections I was getting `java.lang.OutOfMemoryError: GC overhead limit exceeded`, which can be solved by disabling the GC timeout with `-XX:-UseGCOverheadLimit`
- Other times I was getting an error about heap space, so I kept bumping the RAM allocation by 512MB each time (up to 4096m!) it crashed
- This leads to tens of thousands of abandoned files in the assetstore, which need to be cleaned up using `dspace cleanup -v`, or else you'll run out of disk space
- In the end I realized it's better to use submission mode (`-s`) to ingest the community object as a single AIP without its children, followed by each of the collections:
```
$ export JAVA_OPTS="-Dfile.encoding=UTF-8 -Xmx2048m -XX:-UseGCOverheadLimit"
$ [dspace]/bin/dspace packager -s -o ignoreHandle=false -t AIP -e some@user.com -p 10568/87775 /home/aorth/10947-1/10947-1.zip
$ for collection in /home/aorth/10947-1/COLLECTION@10947-*; do [dspace]/bin/dspace packager -s -o ignoreHandle=false -t AIP -e aorth@mjanja.ch -p 10947/1 $collection; done
$ for item in /home/aorth/10947-1/ITEM@10947-*; do [dspace]/bin/dspace packager -r -f -u -t AIP -e aorth@mjanja.ch $item; done
```
- Note that in submission mode DSpace ignores the handle specified in `mets.xml` in the zip file, so you need to turn that off with `-o ignoreHandle=false`
- Give feedback to CIFOR about their data quality:
- Suggestion: uppercase dc.subject, cg.coverage.region, and cg.coverage.subregion in your crosswalk so they match CGSpace and therefore can be faceted / reported on easier
- Suggestion: use CGSpace's CRP names (cg.contributor.crp), see: dspace/config/input-forms.xml
