Agenda & Notes

Review actions from 2020-04-03 Cornell LD4P2 Meeting notes

  • Lynette Rayle QA performance
    • 2020-03-06: Dave in process of converting everything over. Unsure of status for any authority, including MeSH. When LC done, we'll know whether this has impact since there are considerable usage data for LC. Dave and Lynette each working on other projects at the moment.
    • 2020-03-20: Dave is tied up with dept. COVID-19 planning. Log analysis shows two classes of error: 1) 502 is Dave's cache not responding, 2) 500 error which depends on query, Java null pointer error from Dave's system, and fewer of a third 3) timeout error
    • 2020-04-03 On hold because Dave is otherwise tied up
    • 2020-04-10 Lynette has done an analysis of current performance Performance Analysis for QA Lookups – The Getty authorities are pretty much all sub-second which is not too bad, however averaging over all authorities we are around 2s. We find that for ARGOVOC and GEONAMES direct access (without extended context) but when going against the cache we find typically 3-4s with the QA portion (graph load and normalization) approaching a second – Lynette is not yet sure why Geonames has such a large normalization hit for example, why is the graph load time long for Argovoc?
    • 2020-04-17 Did an analysis sorting response time by complexity and size but it didn't show a clear picture, will try a little more analysis next week. When Ligatus and CERL were added - why is Ligatus fast and CERL slow? Dave expects to have more time soon
  • Lynette Rayle  to set up best practices working group around linked data APIs for authorities 
    • 2020-04-10 Got positive responses from some folks about participating including LoC and Casalini, maybe from OCLC and still following up with others → documenting on Linked Data API Best Practices for Authoritative Data Working Group, with target start in early May
    • 2020-04-17 Heard from Christine @ Harvard, Rob @ Getty, Kirk @ OCLC, likely ISNI, nothing from wikidata, have also asked Samvera community – have enough to move forward with a meaningful working group

Status updates and planning

  • Enhanced Discovery - WHAM! (see also https://wiki.duraspace.org/x/sJI7Bg and https://github.com/LD4P/discovery/projects/1)
    • https://docs.google.com/document/d/1u88qVOhp92C6Y1N9dNpNtjV_XOnusFB0nb2aJ-Q10FM/edit
    • 2020-03-20 Consensus from discussion that top priority should be work on the autosuggest, with possibility of additional work on discogs or syllabus. Goal for the next week is to develop plan for autosuggest work and to understand any possible issues
    • 2020-03-25 Discussion with developers, Notes, Slides
    • 2020-04-03 Organizing doc
    • Pseudonym: some thoughts
    • Tim is working on getting data from FAST, broken out by type
    • Huda got herself blocked by LC CloudFlare – working with Kevin to unblock. Working to populate index.
    • Open questions about how to show where a match occurred if not in the main label
    • John is working on understanding the best bets system @ Cornell and our current autocomplete, how we might package our new code as a gem that will work with or override these features.
    • Will continue to build indexes but also start to work on UI 
  • Cataloging Sinatra and other 45's (Discogs data, https://github.com/ld4p/qa_server/issues?q=is%3Aissue+is%3Aopen+label%3ADiscogs)
    • Lookups for place not usable and hence places are not being recorded, relies on work from Dave to fix: https://github.com/LD4P/qa_server/issues/248 & https://github.com/LD4P/qa_server/issues/240
    • Have a currently insurmountable issue with nested profiles. When create Work profile with nested Instance profile there isn't a URI for the Instance (it just gets hung from a bnode). Without a URI the title of the Instance doesn't get indexed. The Sinopia team are unable to fix this in the near term.
    • 2020-03-20 not expecting progress in the near future 
  • Authority Lookups for Sinopia (Lookup infrastructure: https://github.com/LD4P/qa_server/projects/2, Authority requests: https://github.com/LD4P/qa_server/projects/1)
    • 2020-03-27 A couple of updates being put into production now: ISNI now available, Wikidata wasn't working properly because of a lack of response header which has now been added so that it plays nicely with Sinopia, also fix with CERL. Doing some infrastructure work to use Reddis for caching and avoid a memory leak issue, working with Greg to understand issues
    • 2020-04-03 Recently done: cleaned up and updated UBER Issue for Authorities (#253), UBER Issue for Indexing (#239), OCLC FAST cache vs. direct (Sinopia #2125), Use Case: Authority Lookup UI option in place of auto-complete (Sinopia #2123)
