+## 2019-03-10

+- Working on tagging IITA's items with their new research theme (`cg.identifier.iitatheme`) based on their existing IITA subjects (see [notes from 2019-02]({{< relref "2018-02.md" >}}))
+- I exported the entire IITA community from CGSpace and then used `csvcut` to extract only the needed fields:
+
+```
+$ csvcut -c 'id,cg.subject.iita,cg.subject.iita[],cg.subject.iita[en],cg.subject.iita[en_US]' ~/Downloads/10568-68616.csv > /tmp/iita.csv
+```
+
+- After importing to OpenRefine I realized that tagging items based on their subjects is tricky because of the row/record mode of OpenRefine when you split the multi-value cells as well as the fact that some items might need to be tagged twice (thus needing a `||`)
+
+- I think it might actually be easier to filter by IITA subject, then by IITA theme (if needed), and then do transformations with some conditional values in GREL expressions like:
+
+```
+if(isBlank(value), 'PLANT PRODUCTION & HEALTH', value + '||PLANT PRODUCTION & HEALTH')
+```
+
+- Then it's more annoying because there are four IITA subject columns...
+- In total this would add research themes to 1,755 items
+- I want to double check one last time with Bosede that they would like to do this, because I also see that this will tag a few hundred items from the 1970s and 1980s
