Notes

Announcements

• Fedora Camp Atlanta
  
  • May 20-22 at Emory
  • Andrew, Danny, Jared as instructors
• Open Repositories events
  • Fedora user group on Friday
  • Dinner earlier in the week
• FMP Grant survey
  • Survey went out yesterday
  • Open to anyone to complete. About 10 minutes.

Updates from Slack

• #tech
  • Some questions about using JSON-LD
  • Questions around scale, ingest performance, etc.
• #ocfl
  • Conversation around locking
    • Some suggestion that implementation notes should mention different approaches to contention in object updates, uncoordinated applications adding revisions to the same object. Maybe out of scope?
    • Some commenters thinking of scenarios analogous to those we will deal with in Fedora (e.g. many writers making simultaneous changes to an object).
    • How to build up and commit changes to an OCFL object safely. This could go in the implementation notes.
    • Dealing with locking: Fedora will need to answer this question. Less about OCFL and more about the applications built on top of OCFL. 
    • Fedora design includes caching changes until committing to an OCFL object. 
      • Changes are maintained in a deposit space until a version is explicitly created. 
    • OCFL in S3: filesystems can make certain guarantees that are impossible in S3. File paths are not really directories, no true renaming. S3 may only be safe if every client uses a single application that mediates access. 
    • Can locking be cast a a general HTTP issue rather than a Fedora-specific issue?
      • Stateless HTTP requests will need to be managed by a higher-level application
      • It would be useful to have concrete use cases
  • Oxford experimenting with Aaron Birkland's OCFL client
    • Created 250K objects and were pleased with performance

Ready for Review

• Jira
  server DuraSpace JIRA serverId c815ca92-fd23-34c2-8fe3-956808caf8c5 key FCREPO-2991

  • Most of the way through this issue
  • Test still failing in Travis but not locally
  • Null pointer exception, not clear where this is occurring
  • Andrew will try a couple builds and report back

CNI / Leaders / Grant / ACRL Debrief

...

• OCFL instead of ModeShape, implementing the Fedora API, adding a query API
• Strong interest in not releasing Fedora 6.0 without migration support
• Some interest in funding testing. 

...

• Some people may not want OCFL, concerned with optimizing performance and assuming OCFL would have some negative impact

...

Actions

•  Peter Eichman  is planning to work on documenting UMD's fixity check system on the  Fedora in Production: Case Studies wiki page.
•  Danny Bernstein will pull together some use cases for object locking in OCFL
