Notes

1. Announcements
   
   1. sprints channel open & participants invited
   2. #github - Slack integration with github for PRs, ... - Jared will create the new #github channel.
      1. What should we do with GitHub issues?
   3. fcrepo4-docker - has kubernetes support now: Deployment Tooling
   4. #general channel - issue with simple file persistence error. Size is wrong.
      
      1. point Islandora to mysql or postgres for default configuration.
      2. look at updating documentation.
         1. The hyrax setup instructions (https://github.com/samvera/hyrax/wiki/Production-Installation-Overview)
            links to Deploying Fedora 4 Complete Guide
            which says to use https://github.com/fcrepo4/fcrepo4/blob/4.7-maintenance/fcrepo-configs/src/main/resources/config/file-simple/repository.json
            which uses the simple file system persistence approach
2. fcrepo-upgrade-utils
   1. should work for basic setups. People should try it out. Doesn't work with ACLs yet, but that's next.
3. Fedora 6 pilots
   1. OCFL client (https://github.com/pwinckles/ocfl-java-parent) - implements most of the spec.
      1. API - put/get at object level, read/update for individual files. Automatically commits (in single version) at the end of the object update changes.
      2. Doesn't handle multiple clients writing at the same time (& Go client doesn't currently support that, either).
         1. OCFL spec talks about deposit directory for staging content, but defines content at rest, not content in motion.
         2. Aaron suggested OCFL RFCs repo - implementation patterns, definitions, clarifications, ...
         3. What functionality should an OCFL client have? It should be written up.
4. Java 11
   1. Peter's code uses 11. Should make a decision at some point and switch everything.
   2. Ideal scenario:  all fedora eco-system tooling (fcrepo4, fcrepo-came-toolbox, fcrepo-import-export, fcrepo-upgrade-utils) will compile Java 11 source. 
      1. bytecode compatibility ?  Should that go to 11 as well? 
5. Sprint planning

Actions

•  Danny Bernstein  will reach out to Greg about DRASTIC test results
•  Aaron Birkland  to work with Andrew Woods to get the Go client working on travis.
•  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.
•
