CGSpace Notes

2017-10-01

• Peter emailed to point out that many items in the ILRI archive collection have multiple handles:

http://hdl.handle.net/10568/78495||http://hdl.handle.net/10568/79336

• There appears to be a pattern but I’ll have to look a bit closer and try to clean them up automatically, either in SQL or in OpenRefine
• Add Katherine Lutz to the groups for content submission and edit steps of the CGIAR System collections

Rough notes for importing the CGIAR Library content. It was decided that this content would go to a new top-level community called CGIAR System Organization.

• Linode sent an alert that CGSpace (linode18) was using 261% CPU for the past two hours

• Ask Sisay to clean up the WLE approvers a bit, as Marianne’s user account is both in the approvers step as well as the group

• Linode sent an alert that CGSpace (linode18) was using 350% CPU for the past two hours
• I looked in the Activity pane of the Admin Control Panel and it seems that Google, Baidu, Yahoo, and Bing are all crawling with massive numbers of bots concurrently (~100 total, mostly Baidu and Google)
• The good thing is that, according to dspace.log.2017-08-01, they are all using the same Tomcat session
• This means our Tomcat Crawler Session Valve is working
• But many of the bots are browsing dynamic URLs like:
  • /handle/10568/3353/discover
  • /handle/10568/16510/browse
• The robots.txt only blocks the top-level /discover and /browse URLs… we will need to find a way to forbid them from accessing these!
• Relevant issue from DSpace Jira (semi resolved in DSpace 6.0): https://jira.duraspace.org/browse/DS-2962
• It turns out that we’re already adding the X-Robots-Tag "none" HTTP header, but this only forbids the search engine from indexing the page, not crawling it!
• Also, the bot has to successfully browse the page first so it can receive the HTTP header…
• We might actually have to block these requests with HTTP 403 depending on the user agent
• Abenet pointed out that the CGIAR Library Historical Archive collection I sent July 20th only had ~100 entries, instead of 2415
• This was due to newline characters in the dc.description.abstract column, which caused OpenRefine to choke when exporting the CSV
• I exported a new CSV from the collection on DSpace Test and then manually removed the characters in vim using g/^$/d
• Then I cleaned up the author authorities and HTML characters in OpenRefine and sent the file back to Abenet

• Run system updates and reboot DSpace Test

• Merge changes for WLE Phase II theme rename (#329)
• Looking at extracting the metadata registries from ICARDA’s MEL DSpace database so we can compare fields with CGSpace
• We can use PostgreSQL’s extended output format (-x) plus sed to format the output into quasi XML:

• Merge one change to CCAFS flagships that I had forgotten to remove last month (“MANAGING CLIMATE RISK”): https://github.com/ilri/DSpace/pull/317
• Quick proof-of-concept hack to add dc.rights to the input form, including some inline instructions/hints:

• Remove redundant/duplicate text in the DSpace submission license
• Testing the CMYK patch on a collection with 650 items:

$ [dspace]/bin/dspace filter-media -f -i 10568/16498 -p "ImageMagick PDF Thumbnail" -v >& /tmp/filter-media-cmyk.txt

• Run the 279 CIAT author corrections on CGSpace

• Skype with Michael and Peter, discussing moving the CGIAR Library to CGSpace
• CGIAR people possibly open to moving content, redirecting library.cgiar.org to CGSpace and letting CGSpace resolve their handles
• They might come in at the top level in one “CGIAR System” community, or with several communities
• I need to spend a bit of time looking at the multiple handle support in DSpace and see if new content can be minted in both handles, or just one?
• Need to send Peter and Michael some notes about this in a few days
• Also, need to consider talking to Atmire about hiring them to bring ORCiD metadata to REST / OAI
• Filed an issue on DSpace issue tracker for the filter-media bug that causes it to process JPGs even when limiting to the PDF thumbnail plugin: DS-3516
• Discovered that the ImageMagic filter-media plugin creates JPG thumbnails with the CMYK colorspace when the source PDF is using CMYK
• Interestingly, it seems DSpace 4.x’s thumbnails were sRGB, but forcing regeneration using DSpace 5.x’s ImageMagick plugin creates CMYK JPGs if the source PDF was CMYK (see ¹⁰⁵⁶⁸⁄₅₁₉₉₉):

• An item was mapped twice erroneously again, so I had to remove one of the mappings manually:

dspace=# select * from collection2item where item_id = '80278';
  id   | collection_id | item_id
-------+---------------+---------
 92551 |           313 |   80278
 92550 |           313 |   80278
 90774 |          1051 |   80278
(3 rows)
dspace=# delete from collection2item where id = 92551 and item_id = 80278;
DELETE 1

• Create issue on GitHub to track the addition of CCAFS Phase II project tags (#301)
• Looks like we’ll be using cg.identifier.ccafsprojectpii as the field name
