Rails 5.2 Support (Chris Colvard)

  • Audited the Gems which needed to be updated
  • Began working on updates and publishing Gems
  • Planning to issue an announcement on the tech. mailing list
  • AF 12.1.0 was released (with Rails 5.2 support)
  • Then, just a matter of walking back
  • hydra-pcdm, hydra-works, and that might be enough to permit testing for Hyrax
  • hydra-head had an issue with AF 12.1.0 (but this is likely related to an updated Solr Schema)
  • Call for community members of testing Hyrax against Rails 5.2
  • Tom will be looking to update the build matrix

Questioning Authority (Lynette Rayle)

  • Going to release this very soon
  • Major release: significant refactoring of the linked data module
  • Better separation of Classes in the Gem
  • New feature: extended context with the linked data module
  • There are configurations which drive the linked data, URI, Label, and context presented to the user in the UI (to permit them to make better selections)
  • README was becoming really difficult to navigate
  • New documentation was published in the form of the Wiki (please see
  • Also tried to address many issues on the repository
  • pull #210 : Call for testing from anyone uses an authority with unusual characters in the query (this only affects search)
  • This will be tested against Hyrax before the release goes out
  • Public API (methods): LinkedData Module has changed slightly, but everything else is backward-compatible

Universal Viewer (Julie Allinson)

  • Microsoft Edge issue is breaking the pul_uv_rails
  • James from Princeton is going to be contributing to active maintenance of this Gem (as Princeton still uses it)
  • Will turn their focus to this issue, as Princeton needs to update the Gem for other requirements
  • Tom: There is a long-standing item to remove the dependency of Hyrax on this Gem
  • It's preferred to have an alternative which is used more actively by Samvera developers
  • At some point, this will still be yanked
  • Adam: If Hyrax used Webpack, this might also provide a solution to this
  • There is a version 3 branch for the UV, but it has not been released
  • Tom: Agrees with the Webpack-based approach as being desirable
  • Chris: Hyrax 2.4 should permit that one should able to choose a viewer by overriding a partial and using Webpack for the JavaScript dependency

Transferring LDP Gem Ownership (Randall Floyd)

  • Core Components Maintenance WG needs to assist with the transfer of this Gem to Randall
  • Need to ensure that Rails 5.2 support is provided for this Gem
  • Tom: Added this to the agenda for the CCMWG
  • There is a meeting scheduled for this WG on Friday
  • Randall is unavailable, but this will be on the agenda

Coveralls Delays (Lynette Rayle):

  • Reporting from the Coveralls service has been very slow (hours)
  • Adam: This seems to occur infrequently, but it has occurred before
  • Julie: Confirms that this has been observed
  • Adam: PSU started using CodeClimate
  • Has the ability to submit multiple builds for code coverage analysis, along with ABC and cyclomatic complexity analysis
  • CodeClimate is only free for open source repositories
  • Chris: Avalon is using CodeClimate now
