- Announcements:
- Good, well attended meeting in Switzerland. Interest in Fedora 6.
- Value prop of using Valkyrie with/without Fedora
- Fedora 4 & 5 about standardization
- Some performance issues
- Fedora 6 adding more preservation minded features
- Transparent, human-readable filesystem
- Rebuildability from FS
- Why better to use Fedora over Preservica?
- Preservica not active storage
- Fedora offers standard middleware integrations: notifications, robust api
- Fedora 4 & 5 about standardization
- Definition of Fedora rebuild
- Ability to recreate everything needed to run Fedora based on the files on disk (Daniel's exact words should be added here)
- Support unversioned content?
- Some use Fedora to author content over a period of time. They want to version when the content is ready and not have a version of every change.
- Clean version set
- Reduce bloat on disk
- Fedora currently offers the ability to mutate objects and create fixed versions. In OCFL, everything is immutable. How to reconcile this, and maintain Fedora functionality.
- Store everything in OCFL and make version logical structures on top of this
- Store only immutable content in OCFL
- Mutable content stored within OCFL's 'deposit' directory
- Fedora maintains mutable content
- Automatically periodically "flush" staged changes to OCFL
- OCFL versions would not be meaningful – requires logical versions
- There's a possibility that an object could never have a version. Is this okay?
- Auto-versioning should be toggle-able
- Islandora controls versioning – auto-versioning would be off by default
- Where does unversioned content live?
- OCFL 'deposit' directory is intended for short-lived version creation and not long-term storage
- OCFL 'deposit' directory space is out of spec and is up to the individual library to use it as it will
- Some use Fedora to author content over a period of time. They want to version when the content is ready and not have a version of every change.
Actions
- Aaron Birkland to look explore notion of OCFL client with database as authoritative metadata source + asynchronous writing of the inventory.json file
- Peter Eichman and maybe Ben Pennell to make recommendations re transaction side car specification.
- Andrew Woods will look into java 11 transition
