• • PROOF - local system for ordering
  • retrieve files, Edit MARC for Lehigh; save to S3 | Amazon’s Simple Storage Service
  • S3 is remote storage which is provided by Amazon; It has an API so you can read/write files from it
  • submit to Lehigh App
  • FOLIO data import via mod-copycat
• PDA
  • load PDA records
  • blacklight request button; link to Prefect
  • can kick-off workflows in different ways, that is one of them
  • passes HRID of instance to be ordered
  • Brooks in chat: How are you all handling your PDA records for discovery? Are you loading them into FOLIO and harvesting them?
    • indexed to Blacklight
• Cataloger makes metadata corrections in FOLIO
  • instance UUIDs placed in folder by digi pres staff
  • poll for files, export MARC and further steps; send emails
• Setting holdings in OCLC
  • use LDP; core function of a lot of Cornell's automation
  • working on Coutts sync
• Owen: Do you know how the ‘watching the s3 folder’ part works? e.g. is a time scheduled check? Or something more pro-active?
  • Jenn will find out
• Data cleaning
  • Single record imports with OCLC prefixes; remove prefixes
  • reaches out to data export API
  • runs every day
• LDP
  • reports relevant for every morning
  • template to keep working on
• Lamda function
  • watches ArchivesSpace for changes
  • not developed in Prefect, but relates to others

• Kristin: how difficult was it to set this up
  • Jenn is in Technical Services; a lot of work with people in IT
  • no help needed by hosting provider
  • work done outside of FOLIO
  • not plug and play; everything has python script behind it
  • it is a lot of IT work; 
  • frontend workflow engine would be nice to have
  • you can have 3 users with free tier; jump to more users would cost a lot of money
• Kristin: how much time is saved with Prefect for ACQ workflow
  • Jenn: a lot; 
  • Dung-Lan: Yes, I can see what we were able to do in Voyager with Coutts EDI ordering is replicated in the Prefect process Jenn just described.

• Owen: what was decision making process for choosing prefect?
  • team has been skilling up in python, so wanted to use a python framework
• Owen: are the prefect scripts something that can be shared? | re-use with modifications?
  • Jenn: really shareable; built things in chunks
  • all chunks are reusable
• Owen: on FOLIO side, when interacting with FOLIO; does Prefect log in as a user
  • Jenn: it has users
  • user for Prefect
  • user for discovery
  • possible improvement for FOLIO
• Martina S: just to confirm: there is - nevertheless how good this works - a need for a UI in FOLIO?
  • Jenn: yes, there is a Prefect UI, you can click and say: run this now
  • there is a connector from FOLIO
• MartinaS: it seems institutions have found different ways and external tools that fulfill workflow tasks
  • maybe we are rather talking about integarting them all into FOLIO rather than building something completely new in FOLIO
• Owen:
  • FOLIO community could decide on an external tool to use to integrate with FOLIO
  • building FOLIO communities around different external tools
• would not be possible to force institutions into payment for specific tools
• Brooks: implementing a language-agnostic scripting engine for FOLIO would be… a lift
  • I’m not generally a fan of the kitchen sink approach… some things rightfully belong outside FOLIO
• Owen:
  • talked with GBV about how we integrate GOKb
  • Prefect would be a perfect tool for integrating with external KBs
  • if there was consolidation around some tools (like Prefect), it would make things easier

18:09:08 Von  Owen Stephens  an  Alle:
    Could you say what Prefect is?
18:09:42 Von  Owen Stephens  an  Alle:
    OK - thanks. So it can basically talk to multiple systems?
18:09:50 Von  Owen Stephens  an  Alle:
    OK - thank you
18:10:11 Von  Kristin Martin  an  Alle:
    What is S3?
18:10:13 Von  Owen Stephens  an  Alle:
    Sorry - CyberDuck?
18:10:14 Von  Brooks Travis  an  Alle:
    Cyberduck FTW!
18:10:31 Von  Brooks Travis  an  Alle:
    Amazon’s Simple Storage Service
18:10:49 Von  Owen Stephens  an  Alle:
    S3 is remote storage which is provided by Amazon
18:11:02 Von  Owen Stephens  an  Alle:
    It has an API so you can read/write files from it
18:11:21 Von  Brooks Travis  an  Alle:
    A lot of other cloud service providers have S3-compatible storage services, as well.
18:11:47 Von  Brooks Travis  an  Alle:
    (Except for Azure 😕)
18:14:32 Von  Brooks Travis  an  Alle:
    How are you all handling your PDA records for discovery? Are you loading them into FOLIO and harvesting them?
18:17:48 Von  Owen Stephens  an  Alle:
    Do you know how the ‘watching the s3 folder’ part works? e.g. is a time scheduled check? Or something more pro-active?
18:19:21 Von  Owen Stephens  an  Alle:
    Thanks - just curious
18:30:51 Von  Dung-Lan Chen  an  Alle:
    Yes, I can see what we were able to do in Voyager with Coutts EDI ordering is replicated in the Prefect process Jenn just described.
18:34:10 Von  Dennis Bridges  an  Alle:
    Just thought I would confirm that “import orders in MARC format” is coming in Orchid 👍🏻
18:37:01 Von  Kristin Martin  an  Alle:
    Right, but import invoices in MARC format is coming when?
18:43:25 Von  Brooks Travis  an  Alle:
    Yeah, because implementing a language-agnostic scripting engine for FOLIO would be… a lift
18:45:03 Von  Brooks Travis  an  Alle:
    I’m not generally a fan of the kitchen sink approach… some things rightfully belong outside FOLIO
18:45:31 Von  Dung-Lan Chen  an  Alle:
    Jenn, I am wondering if you and your Acquisitions folks who handle the Coutts/OASIS ordering process using Prefect and Lehigh App, etc. can do a presentation about the acquisitions part in one of the upcoming ACQ SIG meetings?
18:45:44 Von  Jenn Colt  an  Alle:
    I think so
18:46:24 Von  Dung-Lan Chen  an  Alle:
    Thank you!!
18:50:56 Von  Brooks Travis  an  Alle:
    Providing an external event notification service would be very helpful…
18:50:57 Von  Laura Daniels  an  Alle:
    it's great having you join us, Jenn
18:51:10 Von  Dung-Lan Chen  an  Alle:
    Yes!!
18:51:14 Von  Brooks Travis  an  Alle:
    In FOLIO
18:51:18 Von  Jenn Colt  an  Alle:
    Yeah brooks a list like that -events, auth management, those things

Transcript

Future topics

• Topic proposal by Owen Stephens for October:
  • Use of shortcut keys and macros for more effective cross-app working  - it also be good to have UX and Stripes/dev knowledge for this discussion I think. I know @Laura (she/they) uses macros so might have insights into the potential for cross-app working
  • Potential for external 'workflow' solutions for cross-app interactions
    • I think 'workflow' is a dangerous term here - in this context it's more about automation than user workflows, although I think there is overlap
    • I was particularly struck by the solution in production at TAMU (Jeremy Huff and Sebastian Hammer presented, the recording is at https://prod-zoom-recordings-openlibraryfoundation-org.s3.amazonaws.com/50dc6c87-3912-43fa-8287-56ec73b12bbb%2Fshared_screen_with_speaker_view%28CC%29.mp4 starting at 3 hrs, 14 min) - I think getting someone from TAMU to talk about how this is used would be v interesting
    • There was also a presentation on the use of a tool called Airflow at Stanford for "bibliographic workflow" but I've not watched that yet so not 100% sure if it is completely applicable - I think the core use case there was systems migration but it may go beyond that
    • Or Jenn Colt on using Prefect
    • does not need to be workflow across apps
• UX/UI and implementers topics
  • should be Wednesdays
• Comprehensive look at where data is copied and stored as opposed to live data | how it is represented
• Date filters and how they work in different apps
