Notes

The participants decided to cancel the second tech meeting from today, as there is an ongoing sprint.

  1. Highlights from last week:
  2. Tomorrow's meeting between Fedora and OCFL team regarding possibly large inentory files in OCFL
    1. regarding fedora implementation of OCFL persistency: no decission has been made so far regarding unversioned content/modifiable head
    2. Idea from Andrew Woods: instead of writing new OCFL version for every change, write all changes to head until explicit Fedora version is created
      1. would mean OCFL versions and Fedora versions are aligned again
      2. no head version, treat latest version as head (no extra directories)
      3. squashing would be possible
      4. Peter Winckles : with this approach it could get tricky to implement updates as atomic operation (create v1, copy to v2, write update to v2); but approach could work
      5. Fedora Leaders and OCFL editors must be contacted to check if this approach is feasable
    3. Do we need to support deleting of mementos if we implement a squashable HEAD?
  3. Sprint Update:
    1. design discussions
      1. Presentation of Flow Diagram Adding Binary to Existing AG by Ben Pennell
    2. core development gateway tickets
      1. FCREPO-3046: should be done later this day(?)
      2. Review of https://github.com/fcrepo/fcrepo-specification-atomic-operations/pull/8
        1. no need to limit transactions to single resources
        2. keep a lot of existing approach for transactions if possible
