Notes
- Folks are largely out today : just a skeleton crew.
- Is it worth exposing an HTTP interface to the OCFL Go client?
- Advantage: decoupled service that can be used for a variety of purposes, not just Fedora
- Disadvantage: performance could suffer, especially when thinking about supporting S3 (client → http → fedora → http → ocfl → http → S3 = lots of hops)
- migration-utils (f3 → ocfl) work is moving forward: Andrew is looking for internally consistent Fedora 3 data sets for testing : will push something up once he's able to run a successful test.
- There is agreement on the team to merge Danny's fcrepo4 PR that removes modeshape.
Actions
- Danny Bernstein will reach out to Greg about DRASTIC test results
- Ben Pennell will review import/export tasks
