At a recent Hydra meeting, developers from five different institutions all realized that they had similar needs to constrain support various types of UI fields based on a variety multiple of internal and external authorities and controlled vocabularies. Their goals was to develop a tool that let them meet these needs in ways that minimized the need for custom coding for each vocabulary. During an intense three-day working session, they minted the initial release of the [https://github.com/projecthydra/questioning_authority/blob/master/README.md questioning authority] gem.
The talk will cover both how cross-institutional development helped speed development and how the gem can be used for accessing both external vocabularies like LCSH and LCNA and for presenting internal vocabulary lists. Although the developing institutions are all Hydra implementers, the gem itself doesn't have any Hydra dependencies and can be used in any Rails or Blacklight based application.
