Whitman College Pilot kickoff
- Second pilot with Fedora IMLS grant
- Involves an Islandora migration
- Using Islandora migration tools
- Actual migration will take place early 2021
- Requires S3 backend
  - Can currently be configured in Fedora, no code changes required
Fedora GitHub orgs/repos have been migrated from fcrepo4 -> fcrepo

One minor, upcoming breaking change https://github.com/fcrepo/fcrepo/pull/1757^{Image Removed}
- Actors of messages has changed

Direct containers
- Currently running tests against various databases
- Approach: dynamically generated, based on DB cache
- Ben will be working on "membershipService" before next week
  - ..as a separate PR based on Direct containers PR
- Future optimization: hash to URI table
- Indirect container implementation yet to be done (https://www.w3.org/TR/ldp/#ldpic^{Image Removed})
Metrics collection
- Adds initial framework available as PR
  - https://github.com/fcrepo/fcrepo/pull/1756^{Image Removed}
- Need to add targeted metrics in order uncover bottlenecks
- Andrew Woods to setup call for discussing metrics visualization

F4->F6 migration
- Version migration is still needed
S3 Support
Fedora API alignment - start with running API test suite
- Full Prefer header support
Managing scenarios of user-provided triples that conflict with triples managed by LDP Direct container
- Filter out triples on PUT to the membership-resource if they include the membership predicate
- On PUT: still require 'lenient' header when including SMTs

/Updates
Planned Breaking Changes (standing topic)
Sprint Update
1. What needs attention
2. Estimates for landing current work
  1. Daniel thinks he'll have PR ready on Friday for exporting F4 mementos
  2. Andrew has been knocking out the PRs
  3. Peter just made PRs for migrating F5 direct and indirect containers to F6
3. Issues to be addressed?
  1. Verify what's going on with fcrepo-import-export versions and which versions support which fcrepo versions
Memento containment
1. In F5, a memento's containment is based on the containment when the memento was created
2. In F6, containment is not captured at the time the memento was created – the containment index only captures the current state, and not historic states
3. What to do?
  1. Add more fields to the containment index similar to what Ben did for membership?
Basic metrics are setup in F6 – https://wiki.lyrasis.org/display/FEDORA6x/Metrics
1. Seeing poor db performance
Verification tool language
Fedora 6 Testing
Designing and developing an OAI-PMH module for Fedora 6.x
1. How much community interest exists for such a module?
  1. Scott is interested and has written some docs
  2. David, Andrew (Daniel?), and Scott will meet and discuss details
2. How difficult would this be to implement?
  1. ?

Danny Bernstein to ensure that a JIRA exists for scenario of transaction does not succeed completely, but rollback does succeed (see: 2020-08-13- Fedora Tech Meeting)
Danny Bernstein document the process of migrating from 4 → 5 → 6
Peter Winckles to create a JIRA to investigate support for optimistic locking and mutable head (see: 2020-08-13- Fedora Tech Meeting)
Who: Clarify in documentation that multiple simultaneous writes to OCFL are not supported
migration-utils - translating RELS-EXT/INT into RDF in Fedora 6: is the functionality there? If not, add it.
Danny Bernstein to organize a special topic call around the topic of high availability.
