- OCFL community meeting
- New java based HTTP server over OCFL
- OCFL commandline client
- Planned breaking changes
- None.
- Sprint wrap-up/Ongoing work
- S3 support/performance improvements
- Peter setup config to run fedora in S3
- Performance improvements made based on results of load testing
- Caching of headers helps reduce the number of requests to S3
- Taking around 5 seconds to create a binary in S3, versus < 100ms in local file system.
- Thomas has tried using S3 synced local file system with Fedora 3. This use is not encouraged, and can be buggy/non-performant.
- Islandora uses external content for S3 storage.
- Memento containment issue
- FCREPO-3450
- HTML UI
- UI should now be as feature rich as Fedora 5.
- No version creation available via the UI if autoversioning is turned on
- Clicking to create a version when there are no changes takes you to the versions page, but does not create a version.
- Direct and Indirect Containers
- DirectContainer membership is being calculated, working on returning it for HEAD and mementos
- f4→f6 migration
- Excluding membership from export, as it should not be importing these generated properties
- Should now support all content types
- F4→F5 migration is largely working, have manually performed F4->F5→F6 transformation, implementing tests
- S3 support/performance improvements
- Alpha Release
- Was being held up by migration util for 3 and 4/5 to 6
- May be able to cut an alpha release next week, for testing usage only.
- Fedora 6 Testing
- Re-ran the API test suite, reduced to 27 errors (was around 47 before). Creating tickets for them as needed.
- There is a utility for deploying Fcrepo to AWS. Will add options for type of storage to mount for it.
- Suggested to change default database to postgres instead of mysql, due to performance
- Multiple errors in RDF, should we return collecting up errors to return together?
- 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.
