Documentation WG (LaRita Robinson)

  • Andrew Myers and LaRita met yesterday
  • Looking for more members
  • Restructuring the site...content is not growing due to a lack of membership, but additional content is still needed
  • Agreed yesterday to push 1-2 issues each week
  • Created a project board for priority issues
  • Try to capture from members who might be knowledgeable, who might be able to fill holes in documentation
  • This week, focusing on workflows and mediated deposits
  • It was started but left incomplete, looking for volunteers who have experience working with this in Hyrax or Samvera apps
  • Go to issue, add comments, offer oneself as a person of contact
  • WG will create the actual content for the site
  • This will hopefully make it easier to create documentation for the site
  • Suggestions for the topics are welcome, create a GitHub issue or contact LaRita or Drew
  • Call for volunteers
  • Specific focus upon creating custom workflows
    • Document how this was successfully undertaken
  • Jim Coble
    • At Duke University, custom workflows were created
    • It was a minor change to a default workflow

Hyrax Pull Request Reviews


Pull Request 3548

  • Chromedriver was failing, this PR installs Google Chrome on CircleCI build containers in order to ensure that Chrome is always stable
  • It does ensure that we remain dependent upon Debian package releases for Chrome stable
  • It was merged

Pull Request 3541

  • Draft PR (new feature introduced by GitHub)
  • Merge icon is grey, otherwise not easily distinguishable from normal PRs
  • Could apply "in progress" label, but this would be unnecessary
  • Should we review them?  Or wait for them to become full PRs?
  • This already had a review
  • "in progress" labels would only be useful if Waffle is used for tracking issues
  • Chris commented requesting a rebase

Backport PRs for CircleCI

Pull Request 3546

  • Transaction becomes a no-op actor
  • Already merged into master, deals with the issue where if you hit an exception in the actor stack, it renders the system unusable
  • IDs would be rolled back (NOIDs), but Fedora wouldn't roll back its own resource
  • NOID would be minted using a Fedora ID for a Fedora resource which already existed
  • This would result in a LDP Conflict
  • This PR ensures that the conflicts are handled and resolved
  • Tom Johnson will handle the CI build issues

Pull Request 3543

  • Alerts users of data loss when moving between tabs while editing Collection metadata
  • No tests are present in the PR
  • This behavior may already be there for certain cases, but not for all cases
  • Tom Johnson commented only 15 hours before this call

Pull Request 3545

  • This is another backport
  • This should require a rebase

Pull Request 3544

  • (This is the same case as 3545)

Pull Request 3468

  • This has not had any activity since last week
  • It was marked as stale, Chris and Tom discussed this last week
  • Tom just needs to come back and introduce additional commits

Pull Request 3489

  • This has had no activity since last week
  • Invite someone from the analytics sprint to perform a review

Pull Request 3472

  • This is going to be abandoned in favor of a PR being introduced by Tom Johnson

Pull Request 3431

  • Chris and Tom discussed this last week
  • Backports support for dealing with transactional request in Noid/Fedora conflict resolution (addressing the same problem as 3546)
  • Lynette Rayle provided a different solution, which set up validation for identifiers
    • Having Noid::Rails check to see if the ID is already in use, and then know to generate a new one
    • It does work and solves a larger problem
    • However, there are concerns about it introducing performance issues
    • Noid ID minting calls out to Fedora, potentially twice (to determine if it exists, two HEAD requests are issued)
    • Unnecessary overhead...and it is dealt with in backports
  • Tom suggested that this just be closed
    • Perhaps place this in the management guide rather than just the README
    • "If you're running into problems, and you need strict validation, you can follow this pattern"
  • Chris commented on the PR


  • Holdover from last Hyrax/Valkyrie sprint, still WIP

Review concluded at 09:36PST/12:36EST
