< li > Then run all system updates and reboot the server< / li >
< li > After the server came back up I cloned the < code > openrxv-items-final< / code > index to < code > openrxv-items-temp< / code > and started the plugins
< ul >
< li > This will hopefully be faster than a full re-harvest… < / li >
< / ul >
< / li >
< li > I opened a few GitHub issues for OpenRXV bugs:
< ul >
< li > < a href = "https://github.com/ilri/OpenRXV/issues/103" > Hide “ metadata structure” section in repository setup< / a > < / li >
< li > < a href = "https://github.com/ilri/OpenRXV/issues/104" > Improve “ start plugins” and “ commit indexing” buttons< / a > < / li >
< li > < a href = "https://github.com/ilri/OpenRXV/issues/105" > Allow running plugins individually< / a > < / li >
< li > < a href = "https://github.com/ilri/OpenRXV/issues/106" > Hide the “ DSpace add missing items” < / a > < / li >
< / ul >
< / li >
< li > Rebuild DSpace Test (linode26) from a fresh Ubuntu 20.04 image on Linode< / li >
< li > The start plugins on AReS had seventy-five errors from the < code > dspace_add_missing_items< / code > plugin for some reason so I had to start a fresh indexing< / li >
< li > I noticed that the WorldFish data has dozens of incorrect countries so I should talk to Salem about that because they manage it
< ul >
< li > Also I noticed that we weren’ t using the Country formatter in OpenRXV for the WorldFish country field, so some values don’ t get mapped properly< / li >
< li > I added some value mappings to fix some issues with WorldFish data and added a few more fields to the repository harvesting config and started a fresh re-indexing< / li >

< li > Margarita from CCAFS asked if we can create a new field for AICCRA publications
< ul >

< li > AICCRA is an initiative so it might be better to create new field for that, for example < code > cg.contributor.initiative< / code > < / li >
