Notes

1. Announcements 
   1. Sprint 2 : There is still room for contributors
   2. Discussion about "mutable head" in OCFL picked up again: https://github.com/OCFL/spec/issues/373
2.  Summary Fedora Leaders meeting report regarding Fedora OCFL unversioned content:
   • David explained the different solutions
   • no decisions were made so far
   • there seems to be some consent on the mutable head solution
   • auto-versioning should not be the default, but be available as an option
3. PersistentStorageSession/FedoraResource conversation : https://docs.google.com/document/d/18rSFqqoxixmozZrgPKON59Ojpg5iOu4lsHDNMm23soY/edit#
   
   • discussion took place yesterday
   • Ben Pennell proposed some changes (see doc): treat fedora resources as immutable objects 
   • might have tiny impacts on already merged pull requests
   • Call for comments till tuesday  , otherwise move forward with proposed solution
4. OCFL Client Updates to support mutable HEAD.
   • Support for mutable HEAD might take around a week of work by Peter Winckles
   • Actual work on client won't be started before OCFL spec has been changed
   • Andrew Woods decision from OCFL editors will probably need 2-3 weeks
   • will the concept of mutable HEAD have implications on transactions:
     • don't commit to OCFL until transaction is committed
     • mutable head makes rollback more complicated
   • Fedora should make clear in documentation that multiple simultaneous writes to OCFL are not supported
5. Sprint prep activities
   • Danny Bernstein: suggests to declare versioning as a nice to have requirement for the next sprint
   • Bethany Seeger: we should at least lay out the basic principles of how versioning we'll be implemented to see if there are implications on the basic CRUD functionality
   • turn integration tests back on to get a clear picture of what is already working
   • brief discussion regarding connection between OCFL versions and Fedora versions:
     • they probably will be aligned again with mutable head (every fedora version is also a ocfl version)
     • unclear if deletion of versions should be supported and how it would be implemented (not scope of this sprint)
6. <add topics here>

Actions

• Aaron Birkland  to look explore notion of OCFL client with database as authoritative metadata source + asynchronous writing of the inventory.json file
• David Wilcox will review the NDSA matrix and pull out the concrete technical requirements that could be considered during the Fedora 6 development.
  
• Call for comments on https://docs.google.com/document/d/18rSFqqoxixmozZrgPKON59Ojpg5iOu4lsHDNMm23soY/edit# till tuesday
• Clarify in in documentation that multiple simultaneous writes to OCFL are not supported
