  • Export a CSV of the IITA community metadata for Martin Mueller

2018-03-06

  • Add three new CCAFS project tags to input-forms.xml (#357)
  • Andrea from Macaroni Bros had sent me an email that CCAFS needs them
  • Give Udana more feedback on his WLE records from last month
  • There were some records using a non-breaking space in their AGROVOC subject field
  • I checked and tested some author corrections from Peter from last week, and then applied them on CGSpace
$ ./fix-metadata-values.py -i Correct-309-authors-2018-03-06.csv -db dspace -u dspace -p 'fuuu' -f dc.contributor.author -t correct -m 3      
$ ./delete-metadata-values.py -i Delete-3-Authors-2018-03-06.csv -db dspace -u dspace-p 'fuuu' -f dc.contributor.author -m 3
  • This time there were no errors in whitespace but I did have to correct one incorrectly encoded accent character
  • Add new CRP subject “GRAIN LEGUMES AND DRYLAND CEREALS” to input-forms.xml (#358)
  • Merge the ORCID integration stuff in to 5_x-prod for deployment on CGSpace soon (#359)
  • Deploy ORCID changes on CGSpace (linode18), run all system updates, and reboot the server
  • Run all system updates on DSpace Test and reboot server
  • I ran the orcid-authority-to-item.py script on CGSpace and mapped 2,864 ORCID identifiers from Solr to item metadata
$ ./orcid-authority-to-item.py -db dspace -u dspace -p 'fuuu' -s http://localhost:8081/solr -d
  • I ran the DSpace cleanup script on CGSpace and it threw an error (as always):
Error: ERROR: update or delete on table "bitstream" violates foreign key constraint "bundle_primary_bitstream_id_fkey" on table "bundle"
  Detail: Key (bitstream_id)=(150659) is still referenced from table "bundle".

  • The solution is, as always:

    $ psql dspace -c 'update bundle set primary_bitstream_id=NULL where primary_bitstream_id in (150659);'
UPDATE 1

  • Apply the proposed PostgreSQL indexes from DS-3636 (pull request #1791 on CGSpace (linode18)

2018-03-07

  • Add CIAT author Mauricio Efren Sotelo Cabrera to controlled vocabulary for ORCID identifiers (#360)
  • Help Sisay proof 200 IITA records on DSpace Test
  • Finally import Udana’s 24 items to IWMI Journal Articles on CGSpace
  • Skype with James Stapleton to discuss CGSpace, ILRI website, CKM staff issues, etc

2018-03-08

  • Looking at a CSV dump of the CIAT community I see there are tons of stupid text languages people add for their metadata
  • This makes the CSV have tons of columns, for example dc.title, dc.title[], dc.title[en], dc.title[eng], dc.title[en_US] and so on!
  • I think I can fix — or at least normalize — them in the database:
dspace=# select distinct text_lang from metadatavalue where resource_type_id=2;
 text_lang 
-----------
 
 ethnob
 en
 spa
 EN
 En
 en_
 en_US
 E.
 
 EN_US
 en_U
 eng
 fr
 es_ES
 es
(16 rows)

dspace=# update metadatavalue set text_lang='en_US' where resource_type_id=2 and text_lang in ('en','EN','En','en_','EN_US','en_U','eng');
UPDATE 122227
dspacetest=# select distinct text_lang from metadatavalue where resource_type_id=2;
 text_lang
-----------

 ethnob
 en_US
 spa
 E.

 fr
 es_ES
 es
(9 rows)
  • On second inspection it looks like dc.description.provenance fields use the text_lang “en” so that’s probably why there are over 100,000 fields changed…
  • If I skip that, there are about 2,000, which seems more reasonably like the amount of fields users have edited manually, or fucked up during CSV import, etc:
dspace=# update metadatavalue set text_lang='en_US' where resource_type_id=2 and text_lang in ('EN','En','en_','EN_US','en_U','eng');
UPDATE 2309
  • I will apply this on CGSpace right now
  • In other news, I was playing with adding ORCID identifiers to a dump of CIAT’s community via CSV in OpenRefine
  • Using a series of filters, flags, and GREL expressions to isolate items for a certain author, I figured out how to add ORCID identifiers to the cg.creator.id field
  • For example, a GREL expression in a custom text facet to get all items with dc.contributor.author[en_US] of a certain author with several name variations (this is how you use a logical OR in OpenRefine):
or(value.contains('Ceballos, Hern'), value.contains('Hernández Ceballos'))
  • Then you can flag or star matching items and then use a conditional to either set the value directly or add it to an existing value:
if(isBlank(value), "Hernan Ceballos: 0000-0002-8744-7918", value + "||Hernan Ceballos: 0000-0002-8744-7918")
  • One thing that bothers me is that this won’t honor author order
  • It might be better to do batches of these in PostgreSQL with a script that takes the place column of an author into account when setting the cg.creator.id
  • I wrote a Python script to read the author names and ORCID identifiers from CSV and create matching cg.creator.id fieldsa: add-orcid-identifiers-csv.py
  • The CSV should have two columns: author name and ORCID identifier:
dc.contributor.author,cg.creator.id
"Orth, Alan",Alan S. Orth: 0000-0002-1735-7458
"Orth, A.",Alan S. Orth: 0000-0002-1735-7458
  • I didn’t integrate the ORCID API lookup for author names in this script for now because I was only interested in “tagging” old items for a few given authors
  • I added ORCID identifers for 187 items by CIAT’s Hernan Ceballos, because that is what Elizabeth was trying to do manually!
  • Also, I decided to add ORCID identifiers for all records from Peter, Abenet, and Sisay as well

2018-03-09

  • Give James Stapleton input on Sisay’s KRAs
  • Create a pull request to disable ORCID authority integration for dc.contributor.author in the submission forms and XMLUI display (#363)

2018-03-11

  • Peter also wrote to say he is having issues with the Atmire Listings and Reports module
  • When I logged in to try it I get a blank white page after continuing and I see this in dspace.log.2018-03-11:
2018-03-11 11:38:15,592 WARN  org.dspace.app.webui.servlet.InternalErrorServlet @ :session_id=91C2C0C59669B33A7683570F6010603A:internal_error:-- URL Was: https://cgspace.cgiar.or

-- step: "1"

org.apache.jasper.JasperException: java.lang.NullPointerException
  • Looks like I needed to remove the Humidtropics subject from Listings and Reports because it was looking for the terms and couldn’t find them
  • I made a quick fix and it’s working now (#364)

2018-03-12

  • Increase upload size on CGSpace’s nginx config to 85MB so Sisay can upload some data

2018-03-13

  • I created a new Linode server for DSpace Test (linode6623840) so I could try the block storage stuff, but when I went to add a 300GB volume it said that block storage capacity was exceeded in that datacenter (Newark, NJ)
  • I deleted the Linode and created another one (linode6624164) in the Fremont, CA region
  • After that I deployed the Ubuntu 16.04 image and attached a 300GB block storage volume to the image
  • Magdalena wrote to ask why there was no Altmetric donut for an item on CGSpace, but there was one on the related CCAFS publication page
  • It looks the the CCAFS publications page fetches the donut using its DOI, whereas CGSpace queries via Handle
  • I will write to Altmetric support and ask them, as perhaps its part of a larger issue
  • CGSpace item: https://cgspace.cgiar.org/handle/10568/89643
  • CCAFS publication page: https://ccafs.cgiar.org/publications/can-scenario-planning-catalyse-transformational-change-evaluating-climate-change-policy
  • Peter tweeted the Handle link and now Altmetric shows the donut for both the DOI and the Handle

2018-03-14

  • Help Abenet with a troublesome Listings and Report question for CIAT author Steve Beebe
  • Continue migrating DSpace Test to the new server (linode6624164)
  • I emailed ILRI service desk to update the DNS records for dspacetest.cgiar.org
  • Abenet was having problems saving Listings and Reports configurations or layouts but I tested it and it works

2018-03-15

  • Help Abenet troubleshoot the Listings and Reports issue again
  • It looks like it’s an issue with the layouts, if you create a new layout that only has one type (dc.identifier.citation):

Listing and Reports layout

  • The error in the DSpace log is:
org.apache.jasper.JasperException: java.lang.ArrayIndexOutOfBoundsException: -1

2018-03-16

  • ICT made the DNS updates for dspacetest.cgiar.org late last night
  • I have removed the old server (linode02 aka linode578611) in favor of linode19 aka linode6624164
  • Looking at the CRP subjects on CGSpace I see there is one blank one so I’ll just fix it:
dspace=# delete from metadatavalue where resource_type_id=2 and metadata_field_id=230 and text_value='';
  • Copy all CRP subjects to a CSV to do the mass updates:
dspace=# \copy (select distinct text_value, count(*) from metadatavalue where resource_type_id=2 and metadata_field_id=230 group by text_value order by count desc) to /tmp/crps.csv with csv header;
COPY 21
  • Once I prepare the new input forms (#362) I will need to do the batch corrections:
$ ./fix-metadata-values.py -i Correct-21-CRPs-2018-03-16.csv -db dspace -u dspace -p 'fuuu' -f cg.contributor.crp -t correct -m 230 -n -d
  • Create a pull request to update the input forms for the new CRP subject style (#366)

2018-03-19

  • Tezira has been having problems accessing CGSpace from the ILRI Nairobi campus since last week
  • She is getting an HTTPS error apparently
  • It’s working outside, and Ethiopian users seem to be having no issues so I’ve asked ICT to have a look
  • CGSpace crashed this morning for about seven minutes and Dani restarted Tomcat
  • Around that time there were an increase of SQL errors:
2018-03-19 09:10:54,856 ERROR org.dspace.storage.rdbms.DatabaseManager @ SQL QueryTable Error -
...
2018-03-19 09:10:54,862 ERROR org.dspace.storage.rdbms.DatabaseManager @ SQL query singleTable Error -
  • But these errors, I don’t even know what they mean, because a handful of them happen every day:
$ grep -c 'ERROR org.dspace.storage.rdbms.DatabaseManager' dspace.log.2018-03-1*
dspace.log.2018-03-10:13
dspace.log.2018-03-11:15
dspace.log.2018-03-12:13
dspace.log.2018-03-13:13
dspace.log.2018-03-14:14
dspace.log.2018-03-15:13
dspace.log.2018-03-16:13
dspace.log.2018-03-17:13
dspace.log.2018-03-18:15
dspace.log.2018-03-19:90
  • There wasn’t even a lot of traffic at the time (8–9 AM):
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "19/Mar/2018:0[89]:" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10
     92 40.77.167.197
     92 83.103.94.48
     96 40.77.167.175
    116 207.46.13.178
    122 66.249.66.153
    140 95.108.181.88
    196 213.55.99.121
    206 197.210.168.174
    207 104.196.152.243
    294 54.198.169.202
  • Well there is a hint in Tomcat’s catalina.out:
Mon Mar 19 09:05:28 UTC 2018 | Query:id: 92032 AND type:2
Exception in thread "http-bio-127.0.0.1-8081-exec-280" java.lang.OutOfMemoryError: Java heap space
  • So someone was doing something heavy somehow… my guess is content and usage stats!
  • ICT responded that they “fixed” the CGSpace connectivity issue in Nairobi without telling me the problem
  • When I asked, Robert Okal said CGNET messed up when updating the DNS for cgspace.cgiar.org last week
  • I told him that my request last week was for dspacetest.cgiar.org, not cgspace.cgiar.org!
  • So they updated the wrong fucking DNS records
  • Magdalena from CCAFS wrote to ask about one record that has a bunch of metadata missing in her Listings and Reports export
  • It appears to be this one: https://cgspace.cgiar.org/handle/10568/83473?show=full
  • The title is “Untitled” and there is some metadata but indeed the citation is missing
  • I don’t know what would cause that

2018-03-20

  • DSpace Test has been down for a few hours with SQL and memory errors starting this morning:
2018-03-20 08:47:10,177 ERROR org.dspace.storage.rdbms.DatabaseManager @ SQL QueryTable Error -
...
2018-03-20 08:53:11,624 ERROR org.dspace.app.xmlui.cocoon.DSpaceCocoonServletFilter @ Serious Error Occurred Processing Request!
org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.OutOfMemoryError: Java heap space
  • I have no idea why it crashed
  • I ran all system updates and rebooted it
  • Abenet told me that one of Lance Robinson’s ORCID iDs on CGSpace is incorrect
  • I will remove it from the controlled vocabulary (#367) and update any items using the old one:
dspace=# update metadatavalue set text_value='Lance W. Robinson: 0000-0002-5224-8644' where resource_type_id=2 and metadata_field_id=240 and text_value like '%0000-0002-6344-195X%';
UPDATE 1
  • Communicate with DSpace editors on Yammer about being more careful about spaces and character editing when doing manual metadata edits
