• Discuss helping CCAFS with some batch tagging of ORCID IDs for their authors
• Discuss how the migration of CGIAR's Active Directory to a flat structure will break our LDAP groups in DSpace
• We had been using DC=ILRI to determine whether a user was ILRI or not
• It looks like we might be able to use OUs now, instead of DCs:

$ ldapsearch -x -H ldaps://svcgroot2.cgiarad.org:3269/ -b "dc=cgiarad,dc=org" -D "admigration1@cgiarad.org" -W "(sAMAccountName=admigration1)"

• User who has been migrated to the root vs user still in the hierarchical structure:

distinguishedName: CN=Last\, First (ILRI),OU=ILRI Kenya Employees,OU=ILRI Kenya,OU=ILRIHUB,DC=CGIARAD,DC=ORG
distinguishedName: CN=Last\, First (ILRI),OU=ILRI Ethiopia Employees,OU=ILRI Ethiopia,DC=ILRI,DC=CGIARAD,DC=ORG

• Changing the DSpace LDAP config to use OU=ILRIHUB seems to work:

• Notes for local PostgreSQL database recreation from production snapshot:

$ dropdb dspacetest
$ createdb -O dspacetest --encoding=UNICODE dspacetest
$ psql dspacetest -c 'alter user dspacetest createuser;'
$ pg_restore -O -U dspacetest -d dspacetest ~/Downloads/cgspace_2016-09-01.backup
$ psql dspacetest -c 'alter user dspacetest nocreateuser;'
$ psql -U dspacetest -f ~/src/git/DSpace/dspace/etc/postgres/update-sequences.sql dspacetest -h localhost
$ vacuumdb dspacetest

• Some names that I thought I fixed in July seem not to be:

dspacetest=# select distinct text_value, authority, confidence from metadatavalue where metadata_field_id=3 and resource_type_id=2 and text_value like 'Poole, %';
      text_value       |              authority               | confidence
-----------------------+--------------------------------------+------------
 Poole, Elizabeth Jane | b6efa27f-8829-4b92-80fe-bc63e03e3ccb |        600
 Poole, Elizabeth Jane | 41628f42-fc38-4b38-b473-93aec9196326 |        600
 Poole, Elizabeth Jane | 83b82da0-f652-4ebc-babc-591af1697919 |        600
 Poole, Elizabeth Jane | c3a22456-8d6a-41f9-bba0-de51ef564d45 |        600
 Poole, E.J.           | c3a22456-8d6a-41f9-bba0-de51ef564d45 |        600
 Poole, E.J.           | 0fbd91b9-1b71-4504-8828-e26885bf8b84 |        600
(6 rows)

• At least a few of these actually have the correct ORCID, but I will unify the authority to be c3a22456-8d6a-41f9-bba0-de51ef564d45

dspacetest=# update metadatavalue set authority='c3a22456-8d6a-41f9-bba0-de51ef564d45', confidence=600 where metadata_field_id=3 and resource_type_id=2 and text_value like 'Poole, %';
UPDATE 69

• And for Peter Ballantyne:

dspacetest=# select distinct text_value, authority, confidence from metadatavalue where metadata_field_id=3 and resource_type_id=2 and text_value like 'Ballantyne, %';
    text_value     |              authority               | confidence
-------------------+--------------------------------------+------------
 Ballantyne, Peter | 2dcbcc7b-47b0-4fd7-bef9-39d554494081 |        600
 Ballantyne, Peter | 4f04ca06-9a76-4206-bd9c-917ca75d278e |        600
 Ballantyne, P.G.  | 4f04ca06-9a76-4206-bd9c-917ca75d278e |        600
 Ballantyne, Peter | ba5f205b-b78b-43e5-8e80-0c9a1e1ad2ca |        600
 Ballantyne, Peter | 20f21160-414c-4ecf-89ca-5f2cb64e75c1 |        600
(5 rows)

• Again, a few have the correct ORCID, but there should only be one authority...

dspacetest=# update metadatavalue set authority='4f04ca06-9a76-4206-bd9c-917ca75d278e', confidence=600 where metadata_field_id=3 and resource_type_id=2 and text_value like 'Ballantyne, %';
UPDATE 58

• And for me:

dspacetest=# select distinct text_value, authority, confidence from metadatavalue where metadata_field_id=3 and resource_type_id=2 and text_value like 'Orth, A%';
 text_value |              authority               | confidence
------------+--------------------------------------+------------
 Orth, Alan | 4884def0-4d7e-4256-9dd4-018cd60a5871 |        600
 Orth, A.   | 4884def0-4d7e-4256-9dd4-018cd60a5871 |        600
 Orth, A.   | 1a1943a0-3f87-402f-9afe-e52fb46a513e |        600
(3 rows)
dspacetest=# update metadatavalue set authority='1a1943a0-3f87-402f-9afe-e52fb46a513e', confidence=600 where metadata_field_id=3 and resource_type_id=2 and text_value like 'Orth, %';
UPDATE 11

• And for CCAFS author Bruce Campbell that I had discussed with CCAFS earlier this week:

dspacetest=# update metadatavalue set authority='0e414b4c-4671-4a23-b570-6077aca647d8', confidence=600 where metadata_field_id=3 and resource_type_id=2 and text_value like 'Campbell, B%';
UPDATE 166
dspacetest=# select distinct text_value, authority, confidence from metadatavalue where metadata_field_id=3 and resource_type_id=2 and text_value like 'Campbell, B%';
       text_value       |              authority               | confidence
------------------------+--------------------------------------+------------
 Campbell, Bruce        | 0e414b4c-4671-4a23-b570-6077aca647d8 |        600
 Campbell, Bruce Morgan | 0e414b4c-4671-4a23-b570-6077aca647d8 |        600
 Campbell, B.           | 0e414b4c-4671-4a23-b570-6077aca647d8 |        600
 Campbell, B.M.         | 0e414b4c-4671-4a23-b570-6077aca647d8 |        600

• After updating the Authority indexes (bin/dspace index-authority) everything looks good
• Run authority updates on CGSpace

• After one week of logging TLS connections on CGSpace:

# zgrep "DES-CBC3" /var/log/nginx/cgspace.cgiar.org-access-ssl.log* | wc -l
217
# zcat -f -- /var/log/nginx/cgspace.cgiar.org-access-ssl.log* | wc -l
1164376
# zgrep "DES-CBC3" /var/log/nginx/cgspace.cgiar.org-access-ssl.log* | awk '{print $6}' | sort | uniq
TLSv1/DES-CBC3-SHA
TLSv1/EDH-RSA-DES-CBC3-SHA

• So this represents 0.02% of 1.16M connections over a one-week period
• Transforming some filenames in OpenRefine so they can have a useful description for SAFBuilder:

value + "__description:" + cells["dc.type"].value

• This gives you, for example: Mainstreaming gender in agricultural R&D.pdf__description:Brief

• Trying to import the records for CIAT from yesterday, but having filename encoding issues from their zip file
• Create a zip on Mac OS X from a SAF bundle containing only one record with one PDF:
  • Filename: Complementing Farmers Genetic Knowledge Farmer Breeding Workshop in Turipaná, Colombia.pdf
  • Imports fine on DSpace running on Mac OS X
  • Fails to import on DSpace running on Linux with error No such file or directory
• Change diacritic in file name from á to a and re-create SAF bundle and zip
  • Success on both Mac OS X and Linux...
• Looks like on the Mac OS X file system the file names represent á as: a (U+0061) + ́ (U+0301)
• See: http://www.fileformat.info/info/unicode/char/e1/index.htm
• See: http://demo.icu-project.org/icu-bin/nbrowser?t=%C3%A1&s=&uv=0
• If I unzip the original zip from CIAT on Windows, re-zip it with 7zip on Windows, and then unzip it on Linux directly, the file names seem to be proper UTF-8
• We should definitely clean filenames so they don't use characters that are tricky to process in CSV and shell scripts, like: ,, ', and "

value.replace("'","").replace(",","").replace('"','')

• I need to write a Python script to match that for renaming files in the file system
• When importing SAF bundles it seems you can specify the target collection on the command line using -c 10568/4003 or in the collections file inside each item in the bundle
• Seems that the latter method causes a null pointer exception, so I will just have to use the former method
• In the end I was able to import the files after unzipping them ONLY on Linux
  • The CSV file was giving file names in UTF-8, and unzipping the zip on Mac OS X and transferring it was converting the file names to Unicode equivalence like I saw above
• Import CIAT Gender Network records to CGSpace, first creating the SAF bundles as my user, then importing as the tomcat7 user, and deleting the bundle, for each collection's items:

$ ./safbuilder.sh -c /home/aorth/ciat-gender-2016-09-06/66601.csv
$ JAVA_OPTS="-Dfile.encoding=UTF-8 -Xmx512m" /home/cgspace.cgiar.org/bin/dspace import -a -e aorth@mjanja.ch -c 10568/66601 -s /home/aorth/ciat-gender-2016-09-06/SimpleArchiveFormat -m 66601.map
$ rm -rf ~/ciat-gender-2016-09-06/SimpleArchiveFormat/
