- After discussion with WLE and CGSpace content people, we decided to just add one metadata field for the WLE Research Themes
- The
cg.identifier.wletheme field will be used for both Phase I and Phase II Research Themes
- Then we’ll create a new sub-community for Phase II and create collections for the research themes there
- The current “Research Themes” community will be renamed to “WLE Phase I Research Themes”
- Tagged all items in the current Phase I collections with their appropriate themes
- Create pull request to add Phase II research themes to the submission form: #328
- Add
cg.subject.system to CGSpace metadata registry, for subject from the upcoming CGIAR Library migration

- After adding
cg.identifier.wletheme to 1106 WLE items I can see the field on XMLUI but not in REST!
- Strangely it happens on DSpace Test AND on CGSpace!
- I tried to re-index Discovery but it didn’t fix it
- Run all system updates on DSpace Test and reboot the server
- After rebooting the server (and therefore restarting Tomcat) the new metadata field is available
- I’ve sent a message to the dspace-tech mailing list to ask if this is a bug and whether I should file a Jira ticket

- Rename WLE’s “Research Themes” sub-community to “WLE Phase I Research Themes” on DSpace Test so Macaroni Bros can continue their testing
- Macaroni Bros tested it and said it’s fine, so I renamed it on CGSpace as well
- Working on how to automate the extraction of the CIAT Book chapters, doing some magic in OpenRefine to extract page from–to from cg.identifier.url and dc.format.extent, respectively:
- cg.identifier.url:
value.split("page=", "")[1]
- dc.format.extent:
value.replace("p. ", "").split("-")[1].toNumber() - value.replace("p. ", "").split("-")[0].toNumber()
- Finally, after some filtering to see which small outliers there were (based on dc.format.extent using “p. 1-14” vs “29 p.”), create a new column with last page number:
cells["dc.page.from"].value.toNumber() + cells["dc.format.pages"].value.toNumber()
- Then create a new, unique file name to be used in the output, based on a SHA1 of the dc.title and with a description:
- dc.page.to:
value.split(" ")[0].replace(",","").toLowercase() + "-" + sha1(value).get(1,9) + ".pdf__description:" + cells["dc.type"].value
- Start processing 769 records after filtering the following (there are another 159 records that have some other format, or for example they have their own PDF which I will process later), using a modified
generate-thumbnails.py script to read certain fields and then pass to GhostScript:
- cg.identifier.url:
value.contains("page=")
- dc.format.extent:
or(value.contains("p. "),value.contains(" p."))
- Command like:
$ gs -dNOPAUSE -dBATCH -dFirstPage=14 -dLastPage=27 -sDEVICE=pdfwrite -sOutputFile=beans.pdf -f 12605-1.pdf
- 17 of the items have issues with incorrect page number ranges, and upon closer inspection they do not appear in the referenced PDF
- I’ve flagged them and proceeded without them (752 total) on DSpace Test:
$ JAVA_OPTS="-Xmx1024m -Dfile.encoding=UTF-8" [dspace]/bin/dspace import --add --eperson=aorth@mjanja.ch --collection=10568/93843 --source /home/aorth/src/CIAT-Books/SimpleArchiveFormat/ --mapfile=/tmp/ciat-books.map &> /tmp/ciat-books.log
- I went and did some basic sanity checks on the remaining items in the CIAT Book Chapters and decided they are mostly fine (except one duplicate and the flagged ones), so I imported them to DSpace Test too (162 items)
- Total items in CIAT Book Chapters is 914, with the others being flagged for some reason, and we should send that back to CIAT
- Restart Tomcat on CGSpace so that the
cg.identifier.wletheme field is available on REST API for Macaroni Bros
