  • Resume working on the MARLO Innovations
    • Last week Jose had sent me an updated CSV with UTF-8 formatting, which was missing the filename column
    • I joined it with the older file (stripped down to just the cg.number and filename columns and then did the same cleanups I had done last week
    • I noticed there are six PDFs unused, so I asked Jose
  • Spent some time trying to understand the REST API submission issues that Rafael from CIAT is having with tip-approve and tip-submit
    • First, according to my notes in 2020-10, a user must be a collection admin in order to submit via the REST API
    • Second, a collection must have a “Accept/Reject/Edit Metadata” step defined in the workflow
    • Also, I referenced my notes from this gist I had made for exactly this purpose! https://gist.github.com/alanorth/40fc3092aefd78f978cca00e8abeeb7a

  • I came up with an interesting idea to add missing countries and AGROVOC terms to the MARLO Innovation metadata
    • I copied the abstract column to two new fields: countrytest and agrovoctest and then used this Jython code as a transform to drop terms that don’t match (using CGSpace’s country list and list of 1,400 AGROVOC terms):
with open(r"/tmp/cgspace-countries.txt",'r') as f :
    countries = [name.rstrip().lower() for name in f]

return "||".join([x for x in value.split(' ') if x.lower() in countries])
  • Then I joined them with the other country and AGROVOC columns
    • I had originally tried to use csv-metadata-quality to look up and drop invalid AGROVOC terms but it was timing out ever dozen or so requests
    • Then I briefly tried to use lightrdf to export a text file of labels from AGROVOC’s RDF, but I couldn’t figure it out
    • I just realized this will not match countries with spaces in our cell value, ugh… and Jython has weird syntax and errors and I can’t get normal Python code to work here, I’m missing something
  • Then I extracted the titles, dates, and types and added IDs, then ran them through check-duplicates.py to find the existing items on CGSpace so I can add them as dcterm.relation links
$ csvcut -l -c dc.title,dcterms.issued,dcterms.type ~/Downloads/2022-08-03-Innovations-Cleaned.csv | sed '1s/line_number/id/' > /tmp/innovations-temp.csv
$ ./ilri/check-duplicates.py -i /tmp/innovations-temp.csv -u dspacetest -db dspacetest -p 'dom@in34sniper' -o /tmp/ccafs-duplicates.csv
  • There were about 115 with existing items on CGSpace
  • Then I did some minor processing and checking of the duplicates file (for example, some titles appear more than once in both files), and joined with the other file (left join):
$ csvjoin --left -c dc.title ~/Downloads/2022-08-03-Innovations-Cleaned.csv ~/Downloads/2022-08-03-Innovations-relations.csv > /tmp/innovations-with-relations.csv
  • Then I used SAFBuilder to create a SimpleItemArchive and import to DSpace Test:
$ export JAVA_OPTS="-Dfile.encoding=UTF-8 -Xmx2048m"
$ dspace import --add --eperson=aorth@mjanja.ch --source /tmp/SimpleArchiveFormat --mapfile=./2022-08-03-innovations.map
  • Meeting with Mohammed Salem about harmonizing MEL and CGSpace metadata fields
    • I still need to share our results and recommendations with Peter, Enrico, Sara, Svetlana, et al
  • I made some minor fixes to csv-metadata-quality while working on the MARLO CRP Innovations

  • I discussed issues with the DSpace 7 submission forms on Slack and Mark Wood found that the migration tool creates a non-working submission form
    • After updating the class name of the collection step and removing the “complete” and “sample” steps the submission form was working
    • Now the issue is that the controlled vocabularies show up like this:

Controlled vocabulary bug in DSpace 7

  • I think we need to add IDs, I will have to check what the implications of that are
  • Emilio contacted me last week to say they have re-worked their harvester on Hetzner to use a new user agent: AICCRA website harvester
    • I verified that I see it in the REST API logs, but I don’t see any new stats hits for it
    • I do see 11,000 hits from that IP last month when I had the incorrect nginx configuration that was sending a literal $http_user_agent so I purged those
    • It is lucky that we have harvest in the DSpace spider agent example file so Solr doesn’t log these hits, nothing needed to be done in nginx

  • I noticed there was high load on CGSpace, around 9 or 10
    • Looking at the Munin graphs it seems to just be the last two hours or so, with a slight increase in PostgreSQL connections, firewall traffic, and a more noticeable increase in CPU
    • DSpace sessions are normal
    • The number of unique hosts making requests to nginx is pretty low, though it’s only 6AM in the server’s time
  • I see one IP in Sweden making a lot of requests with a normal user agent: 80.248.237.167
    • This host is on Internet Vikings (INTERNETBOLAGET), and I see 140,000 requests from them in Solr
    • I see reports of excessive scraping on AbuseIPDB.com
    • I’m gonna add their 80.248.224.0/20 to the bot-networks.conf in nginx
    • I will also purge all the hits from this IP in Solr statistics
  • I also see the core.ac.uk bot making tens of thousands of requests today, but we are already tagging that as a bot in Tomcat’s Crawler Session Manager valve, so they should be sharing a Tomcat session with other bots and not creating too many sessions
