Notes

• Welcome

  • Hyrax/Fedora working group will present at Samvera Connect

• Updates

  • Working on migration tooling primarily worked on by Softserv for Hyku. Updating the Dassie app to make use of it.

  • Freya - adapter for postgres

  • Frigg - adapter for fedora 6 - commented out waiting on other work

  • Required for support of Fedora 6

    • Issue with admin set default IDs which contain a slash, may work on in the developer congress

      • admin_set/default is the default admin set

      • Causes an error in Fedora 6 even when options are set that supposed to allow the / to be encoded

      • Colin - recommends changing name of default admin set to not contain URL unsafe character

        • Concern is that users may have other encoded slashes or characters in non-hyrax standard IDs, so we would not be able to address that in hyrax

      • Fedora Jira issue for the problem https://fedora-repository.atlassian.net/jira/software/c/projects/FCREPO/issues/FCREPO-3933?jql=project%20%3D%20%22FCREPO%22%20ORDER%20BY%20created%20DESC

        • Currently believe it is a tomcat issue, since the version of tomcat in docker went up between versions of Fedora.

      • Valkyrie needs to be updated to work with pair trees

      • Files in filesets, or filesets themselves (can’t remember which) attached to do not get put into pair trees at the moment

      • To enable pair trees, have to pass in docker configuration options

  • Emory update

    • When persisting binaries to S3 through fedora 6, the binaries are not persisted with any mimetype or filename. So files are only interpretable through hyrax/fedora, since there is no info about what they are in S3. Not sure if its a fedora or hyrax issue

      • Tom - can set the filename via setting Slug, and mimetype with header.

        • They use hyrax 2.6 with a custom fedora 6 adapter https://github.com/bodleian/fedora6_client/blob/develop/lib/fedora6/client.rb

        • Not sure if doing this in valkyrie would be a problem or not, would need to investigate

          • Looks like there is support for content-type in valkyrie, but the more recent versioned object type does not currently support it, so that will need to be added in.

      • It looks like ocfl-java does allow content-types to be supplied when uploading files:

        • https://github.com/OCFL/ocfl-java/blob/05aa875d50a8f8e9fc58bba825c9ffce43dc3699/ocfl-java-aws/src/main/java/io/ocfl/aws/OcflS3Client.java#L182

      • Sirenia issue: https://github.com/samvera/hyrax/issues/6521

        • Most likely resolved now by other PRs that were taking place - Emily will add comments to the ticket, and maintenance working group will re-test.

• Nurax setup / Performance testing

  • Next steps are to outline what we want to test
