CGSpace Notes

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

  • I checked to see if the Solr sharding task that is supposed to run on January 1st had run and saw there was an error
  • I tested on DSpace Test as well and it doesn’t work there either
  • I asked on the dspace-tech mailing list because it seems to be broken, and actually now I’m not sure if we’ve ever had the sharding task run successfully over all these years

2017-01-04

  • I tried to shard my local dev instance and it fails the same way:

  • Very interesting… it creates the core and then fails somehow

2017-01-08

  • Put Sisay’s item-view.xsl code to show mapped collections on CGSpace (#295)

2017-01-09

  • A user wrote to tell me that the new display of an item’s mappings had a crazy bug for at least one item: https://cgspace.cgiar.org/handle/10568/78596
  • She said she only mapped it once, but it appears to be mapped 184 times

Crazy item mapping

2017-01-10

  • I tried to clean up the duplicate mappings by exporting the item’s metadata to CSV, editing, and re-importing, but DSpace said “no changes were detected”
  • I’ve asked on the dspace-tech mailing list to see if anyone can help
  • I found an old post on the mailing list discussing a similar issue, and listing some SQL commands that might help
  • For example, this shows 186 mappings for the item, the first three of which are real:
dspace=#  select * from collection2item where item_id = '80596';
  • Then I deleted the others:
dspace=# delete from collection2item where item_id = '80596' and id not in (90792, 90806, 90807);
  • And in the item view it now shows the correct mappings
  • I will have to ask the DSpace people if this is a valid approach
  • Finish looking at the Journal Title corrections of the top 500 Journal Titles so we can make a controlled vocabulary from it

Traceback (most recent call last):
  File "./fix-metadata-values.py", line 80, in <module>
    print("Fixing {} occurences of: {}".format(records_to_fix, record[0]))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe4' in position 15: ordinal not in range(128)
  • Seems we need to encode as UTF-8 before printing to screen, ie:
print("Fixing {} occurences of: {}".format(records_to_fix, record[0].encode('utf-8')))
  • See: http://stackoverflow.com/a/36427358/487333
  • I’m actually not sure if we need to encode() the strings to UTF-8 before writing them to the database… I’ve never had this issue before
  • Now back to cleaning up some journal titles so we can make the controlled vocabulary:
$ ./fix-metadata-values.py -i /tmp/fix-27-journal-titles.csv -f dc.source -t correct -m 55 -d dspace -u dspace -p 'fuuu'
  • Now get the top 500 journal titles:
dspace-# \copy (select distinct text_value, count(*) from metadatavalue where resource_type_id=2 and metadata_field_id=55 group by text_value order by count desc limit 500) to /tmp/journal-titles.csv with csv;
  • The values are a bit dirty and outdated, since the file I had given to Abenet and Peter was from November
  • I will have to go through these and fix some more before making the controlled vocabulary
  • Added 30 more corrections or so, now there are 49 total and I’ll have to get the top 500 after applying them

2017-01-13

2017-01-16

  • Fix the two items Maria found with duplicate mappings with this script:
/* 184 in correct mappings: https://cgspace.cgiar.org/handle/10568/78596 */
delete from collection2item where item_id = '80596' and id not in (90792, 90806, 90807);
/* 1 incorrect mapping: https://cgspace.cgiar.org/handle/10568/78658 */
delete from collection2item where id = '91082';

  • Helping clean up some file names in the 232 CIAT records that Sisay worked on last week
  • There are about 30 files with %20 (space) and Spanish accents in the file name
  • At first I thought we should fix these, but actually it is prescribed by the W3 working group to convert these to UTF8 and URL encode them!
  • And the file names don’t really matter either, as long as the SAF Builder tool can read them—after that DSpace renames them with a hash in the assetstore
  • Seems like the only ones I should replace are the ' apostrophe characters, as %27:
value.replace("'",'%27')
  • Add the item’s Type to the filename column as a hint to SAF Builder so it can set a more useful description field:
value + "__description:" + cells["dc.type"].value
  • Test importing of the new CIAT records (actually there are 232, not 234):
$ JAVA_OPTS="-Xmx512m -Dfile.encoding=UTF-8" /home/dspacetest.cgiar.org/bin/dspace import --add --eperson=aorth@mjanja.ch --collection=10568/79042 --source /home/aorth/CIAT_234/SimpleArchiveFormat/ --mapfile=/tmp/ciat.map &> /tmp/ciat.log
  • Many of the PDFs are 20, 30, 40, 50+ MB, which makes a total of 4GB
  • These are scanned from paper and likely have no compression, so we should try to test if these compression techniques help without comprimising the quality too much:
$ convert -compress Zip -density 150x150 input.pdf output.pdf
$ gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf
  • Somewhere on the Internet suggested using a DPI of 144

2017-01-19

  • In testing a random sample of CIAT’s PDFs for compressability, it looks like all of these methods generally increase the file size so we will just import them as they are
  • Import 232 CIAT records into CGSpace:
$ JAVA_OPTS="-Xmx512m -Dfile.encoding=UTF-8" /home/cgspace.cgiar.org/bin/dspace import --add --eperson=aorth@mjanja.ch --collection=10568/68704 --source /home/aorth/CIAT_232/SimpleArchiveFormat/ --mapfile=/tmp/ciat.map &> /tmp/ciat.log

2017-01-22

  • Looking at some records that Sisay is having problems importing into DSpace Test (seems to be because of copious whitespace return characters from Excel’s CSV exporter)
  • There were also some issues with an invalid dc.date.issued field, and I trimmed leading / trailing whitespace and cleaned up some URLs with unneeded parameters like ?show=full

2017-01-23

  • I merged Atmire’s pull request into the development branch so they can deploy it on DSpace Test
  • Move some old ILRI Program communities to a new subcommunity for former programs (10568/79164):
$ for community in 10568/171 10568/27868 10568/231 10568/27869 10568/150 10568/230 10568/32724 10568/172; do /home/cgspace.cgiar.org/bin/dspace community-filiator --remove --parent=10568/27866 --child="$community" && /home/cgspace.cgiar.org/bin/dspace community-filiator --set --parent=10568/79164 --child="$community"; done

  • Run all updates on DSpace Test and reboot the server
  • Run fixes for Journal titles on CGSpace:
$ ./fix-metadata-values.py -i /tmp/fix-49-journal-titles.csv -f dc.source -t correct -m 55 -d dspace -u dspace -p 'password'
  • Create a new list of the top 500 journal titles from the database:
dspace-# \copy (select distinct text_value, count(*) from metadatavalue where resource_type_id=2 and metadata_field_id=55 group by text_value order by count desc limit 500) to /tmp/journal-titles.csv with csv;
  • Then sort them in OpenRefine and create a controlled vocabulary by manually adding the XML markup, pull request (#298)
  • This would be the last issue remaining to close the meta issue about switching to controlled vocabularies (#69)

2017-01-25

  • Atmire says the com.atmire.statistics.util.UpdateSolrStorageReports and com.atmire.utils.ReportSender are no longer necessary because they are using a Spring scheduler for these tasks now
  • Pull request to remove them from the Ansible templates: https://github.com/ilri/rmg-ansible-public/pull/80
  • Still testing the Atmire modules on DSpace Test, and it looks like a few issues we had reported are now fixed:
    • XLS Export from Content statistics
    • Most popular items
    • Show statistics on collection pages
  • But now we have a new issue with the “Types” in Content statistics not being respected—we only get the defaults, despite having custom settings in dspace/config/modules/atmire-cua.cfg

2017-01-27

  • Magdalena pointed out that somehow the Anonymous group had been added to the Administrators group on CGSpace (!)
  • Discuss plans to update CCAFS metadata and communities for their new flagships and phase II project identifiers
  • The flagships are in cg.subject.ccafs, and we need to probably make a new field for the phase II project identifiers

2017-01-28

  • Merge controlled vocabulary for journal titles (dc.source) into CGSpace (#298)
  • Merge new CIAT subject into CGSpace (#296)

2017-01-29

  • Run all system updates on DSpace Test, redeploy DSpace code, and reboot the server
  • Run all system updates on CGSpace, redeploy DSpace code, and reboot the server
