Documenting day-to-day work on the CGSpace repository.

July, 2023

in  Notes

2023-07-01

  • Export CGSpace to check for missing Initiative collection mappings
  • Start harvesting on AReS

2023-07-02

  • Minor edits to the crossref_doi_lookup.py script while running some checks from 22,000 CGSpace DOIs

2023-07-03

  • I analyzed the licenses declared by Crossref and found with high confidence that ~400 of ours were incorrect
    • I took the more accurate ones from Crossref and updated the items on CGSpace
    • I took a few hundred ISBNs as well for where we were missing them
    • I also tagged ~4,700 items with missing licenses as “Copyrighted; all rights reserved” based on their Crossref license status being TDM, mostly from Elsevier, Wiley, and Springer
    • Checking a dozen or so manually, I confirmed that if Crossref only has a TDM license then it’s usually copyrighted (could still be open access, but we can’t tell via Crossref)
    • I would be curious to write a script to check the Unpaywall API for open access status…
    • In the past I found that their license status was not very accurate, but the open access status might be more reliable
  • More minor work on the DSpace 7 item views
    • I learned some new Angular template syntax
    • I created a custom component to show Creative Commons licenses on the simple item page
    • I also decided that I don’t like the Impact Area icons as a component because they don’t have any visual meaning

2023-07-04

  • Focus group meeting with CGSpace partners about DSpace 7
  • I added a themed file selection component to the CGSpace theme
    • It displays the bistream description instead of the file name, just like we did in DSpace 6 XMLUI
  • I added a custom component to show share icons

2023-07-05

  • I spent some time trying to update OpenRXV from Angular 9 to 10 to 11 to 12 to 13
    • Most things work but there are some minor bugs it seems
  • Mishell from CIP emailed me to say she was having problems approving an item on CGSpace
    • Looking at PostgreSQL I saw there were a dozen or so locks that were several hours and even over one day old so I killed those processes and told her to try again

2023-07-06

  • Types meeting
  • I wrote a Python script to check Unpaywall for some information about DOIs

2023-07-7

  • Continue exploring Unpaywall data for some of our DOIs
    • In the past I’ve found their licensing information to not be very reliable (preferring Crossref), but I think their open access status is more reliable, especially when the provider is listed as being the publisher
    • Even so, sometimes the version can be “acceptedVersion”, which is presumably the author’s version, as opposed to the “publishedVersion”, which means it’s available as open access on the publisher’s website
    • I did some quality assurance and found ~100 that were marked as Limited Access, but should have been Open Access, and fixed a handful of licenses
  • Delete duplicate metadata as describe in my DSpace issue from last year: https://github.com/DSpace/DSpace/issues/8253
  • Start working on some statistics on AGROVOC usage for my presenation next week
    • I used the following SQL query to dump values from all subject fields and lower case them:
localhost/dspacetest= ☘ \COPY (SELECT DISTINCT(lower(text_value)) AS "subject" FROM metadatavalue WHERE dspace_object_id in (SELECT dspace_object_id FROM item) AND metadata_field_id IN (187, 120, 210, 122, 215, 127, 208, 124, 128, 123, 125, 135, 203, 236, 238, 119)) to /tmp/2023-07-07-cgspace-subjects.csv WITH CSV HEADER;
COPY 26443
Time: 2564.851 ms (00:02.565)
  • Then I extracted the subjects and looked them up against AGROVOC:
$ csvcut -c subject /tmp/2023-07-07-cgspace-subjects.csv | sed '1d' > /tmp/2023-07-07-cgspace-subjects.txt
$ ./ilri/agrovoc_lookup.py -i /tmp/2023-07-07-cgspace-subjects.txt -o /tmp/2023-07-07-cgspace-subjects-results.csv
  • I did some more tests with Angular 13 on OpenRXV and found out why the repository type dropdown wasn’t working
    • It was because of a missing 1-line JSON file in the data directory, which is runtime data, not code
    • I copied the data directory from the production serve and rebuild and the site is working well now
    • I did a full harvest with plugins and it worked!
    • So it seems Angular 13.4.0 will work, yay

2023-07-08

  • Export CGSpace to check for missing Initiative collection mappings
    • Start a harvest on AReS
  • The AGROVOC lookup finished, so I checked the number of matches:
$ csvgrep -c 'match type' -r '^.+$' ~/Downloads/2023-07-07-cgspace-subjects-resolved.csv | sed 1d | wc -l
12528
  • So that’s 12,528 out of 26,443 unique terms (47.3%)
  • I did a LOT of work on the OpenRXV frontend build dependencies to bring more in line with Angular 13

2023-07-10

  • I did a lot more work on OpenRXV to test and update dependencies
  • I deployed the latest version on the production server

2023-07-12

  • CGSpace upgrade meeting with Americas and Africa group

2023-07-13

  • Michael Victor asked me to help Aditi extract some information from CGSpace
    • She was interested in journal articles published between 2018 and 2023 with a range of subjects related to drought, flooding, resilience, etc
    • I used an advanced query with some AGROVOC terms:
dcterms.issued:[2018 TO 2023] AND dcterms.type:"Journal Article" AND (dcterms.subject:flooding OR dcterms.subject:flood OR dcterms.subject:"extreme weather events" OR dcterms.subject:drought OR dcterms.subject:"drought resistance" OR dcterms.subject:"drought tolerance" OR dcterms.subject:"soil salinity" OR dcterms.subject:"pests of plants" OR dcterms.subject:pests OR dcterms.subject:heat OR dcterms.subject:fertilizers OR dcterms.subject:"fertilizer technology" OR dcterms.subject:"rice fields" OR dcterms.subject:"landscape conservation" OR dcterms.subject:"landscape restoration" OR dcterms.subject:livestock)
  • Interestingly, some variations of this same exact query produce no search results, and I see this error in the DSpace log:
org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'dcterms.issued:[2018 TO 2023] AND dcterms.type:"Journal Article" AND (dcterms.subject:flooding OR dcterms.subject:flood OR dcterms.subject:"extreme weather events" OR dcterms.subject:drought OR dcterms.subject:"drought resistance" OR dcterms.subject:"drought tolerance" OR dcterms.subject:"soil salinity" OR dcterms.subject:"pests of plants" OR dcterms.subject:pests OR dcterms.subject:heat OR dcterms.subject:fertilizers OR dcterms.subject:"fertilizer technology" OR dcterms.subject:"rice fields" OR dcterms.subject:livestock OR dcterms.subject:"landscape conservation" OR dcterms.subject:"landscape restoration\"\)': Lexical error at line 1, column 617.  Encountered: <EOF> after : "\"landscape restoration\\\"\\)"
  • It seems to be when there is a quoted search term at the end of the parenthesized group
    • For what it’s worth this same query worked fine on DSpace 7.6

2023-07-15

  • Export CGSpace to fix missing Initiative collection mappings
  • Start a harvest on AReS

2023-07-17

  • Rasika had sent me a list of new ORCID identifiers for new IWMI staff so I combined them with our existing list and ran resolve_orcids.py to refresh the names in our database
    • I updated the list, updated names in the database, and tagged new authors with missing identifiers in existing items

2023-07-18

  • Meeting with IWMI, IRRI, and IITA colleagues about CGSpace upgrade plans
  • Maria from the Alliance mentioned having some submissions stuck on CGSpace
    • I looked and found a number of locks stuck for many nineteen, eighteen, and more hours…
    • I killed them and told her to try again
$ psql < locks-age.sql | less -S
$ psql < locks-age.sql | grep -E " (19|18|17|16|12):" | awk -F"|" '{print $10}' | sort -u | xargs kill

2023-07-19

  • I had to kill a bunch more locked processes in PostgreSQL, I’m not sure what’s going on
  • After some discussion about an advanced search bug with Tim on Slack, I filed an issue on GitHub

2023-07-20

  • I added a new metadata field for CGIAR Impact Platforms (cg.subject.impactPlatform) to CGSpace

2023-07-22

  • Export CGSpace tp fix missing Initiative collections
  • Start a harvest on AReS

2023-07-24

  • Test Salem’s new JavaScript-based DSpace Statistics API and send him some feedback
  • I noticed a few times that the Solr service on my DSpace 7 instance is getting OOM killed
    • I had been using a 4g Solr heap, but maybe we don’t need that much
    • Tomcat is also using 4.6GB, and then there’s PostgreSQL… so perhaps it’s all a bit much on this system now

2023-07-25

  • Start testing exporting DSpace 6 Solr cores to import on DSpace 7:
$ chrt -b 0 dspace solr-export-statistics -i statistics
  • I’m curious how long it takes and how much data there will be
    • The size of the Solr data directory is currently 82GB
    • The export took about 2.5 hours and created 6,000 individual CSVs, one for each day of Solr stats
    • The size of the exported CSVs is about 88GB
    • I will copy just a few years to import on the DSpace 7 test server
    • So importing these is going to require removing the Atmire custom fields:
$ dspace solr-import-statistics -i statistics
Exception: Error from server at http://localhost:8983/solr/statistics: ERROR: [doc=1a92472e-e39d-4602-9b4d-da022df8f233] unknown field 'containerCommunity'

  • I will try using solr-import-export-json, which I’ve used in the past to skip Atmire custom fields in Solr:
$ chrt -b 0 ./run.sh -s http://localhost:8081/solr/statistics -a export -o /tmp/statistics-2022.json -f 'time:[2022-01-01T00\:00\:00Z TO 2022-12-31T23\:59\:59Z]' -k uid -S author_mtdt,author_mtdt_search,iso_mtdt_search,iso_mtdt,subject_mtdt,subject_mtdt_search,containerCollection,containerCommunity,containerItem,countryCode_ngram,countryCode_search,cua_version,dateYear,dateYearMonth,geoipcountrycode,geoIpCountryCode,ip_ngram,ip_search,isArchived,isInternal,isWithdrawn,containerBitstream,file_id,referrer_ngram,referrer_search,userAgent_ngram,userAgent_search,version_id,complete_query,complete_query_search,filterquery,ngram_query_search,ngram_simplequery_search,simple_query,simple_query_search,range,rangeDescription,rangeDescription_ngram,rangeDescription_search,range_ngram,range_search,actingGroupId,actorMemberGroupId,bitstreamCount,solr_update_time_stamp,bitstreamId,core_update_run_nb
  • Some users complained that CGSpace was slow and I found a handful of locks that were hours and days old…
    • I killed those and told them to try again
  • After importing the Solr statistics into DSpace 7 I realized that my DSpace Statistics API will work fine
    • I made some minor modifications to the Ansible infrastructure scripts to make sure it is enabled and then activated it on DSpace 7 Test
