Notes

Announcements

David Wilcox : Summarizing current work regarding community interactions:

• Online Fedora 
• Building training materials for Fedora 6 → who would/can contribute?
• One online user group meetings/trainings in US
• probably another in European timezone
• Announcements will follow
• Goal keep up community interactions
• fcrepo-terraform project –> can it be made public?

Sprint updates:

Danny Bernstein : Summarizing progress of current sprint:

• All in all: good progress
• Open questions/remarks regarding simple search?
• Simple search:
  • Searching for containment relationships use case? → might make ACL implementation easier
  • include Google Doc (https://docs.google.com/document/d/1nFmvIRmMkGx93hqJUp9unw0RWwqb_DBx8-dvGSSP4iY/edit#) into wiki
• WebAC progress:
  • Jared Whiklo: currently slow
• Testing:
  • API test suite reactivated by Andrew Woods
  • a lot of tests are already passing
• Tickets in review:
  • Unable to locate Jira server for this macro. It may be due to Application Link configuration. should be ready
  • Unable to locate Jira server for this macro. It may be due to Application Link configuration. probably depends on FCREPO-3297, documentation on wiki needs review

Alignment on "Fedora OCFL Storage"

Peter Winckles : summarizing proposal from https://pad.disroot.org/p/874NsxcjLLAAwgIRg2kh

• OCFL objects should be transparent → files on disk match expectations of users what should be in that object
• handle conflicting filenames in OCFL storage, 3 approaches:
  • adding a reserved prefix/suffix → users would be unable to create resources with that prefix/suffix
    • certain files created by fedora will have that prefix/suffix
  • store system generated files in separate directory
    • not outlined in document
    • downside: more directories
    • resource is never in the OCFL object root directory → might be unexpected by users
  • no expectation where a ressource is stored
    • Fedora would have to check the resource headers to find conflicts
    • conflicts are resolved by adding a mapping to the resource headers (if a file needs to be stored under a different name)
    • most of the time, files are exactly where they should be, unless there is a collision
• approaches should be discussed in separate meeting
• main question: transparency of ocfl vs. easier to handle implementation
• Ben Cail favors solution with separate directories
• discussion related to handling Vanilla OCFL –> one approach here is to treat all files Vanilla OCFL objects as binaries
• proposal by Andrew Woods : don't replicate the fedora id into the filename, but use fixed names
  • Jared Whiklo: might lead to conflicts with binaries

Remove Fedora-related JMS messaging headers

Not discussed this week.

Containment Index

Not discussed this week.

Change versioning default to opt-out of auto-versioning?

Not discussed this week.

Actions

• Danny Bernstein to ensure that a JIRA exists for scenario of transaction does not succeed completely, but rollback does succeed (see: 2020-05-07 - Fedora Tech Meeting)
• Peter Winckles to create a JIRA to investigate support for optimistic locking and mutable head (see: 2020-05-07 - Fedora Tech Meeting)
• Who:  Clarify in documentation that multiple simultaneous writes to OCFL are not supported
• Who:  After team has a chance to comment, send Ghost Node idea to general community for feedback
• Who: Decide who works on what in the next sprint
  
• Thomas Bernhart Update some of documentation pages for Fedora 6 (with findings from building the docker container)
