  13. 13. Tools we used•! Web App: •! Ruby on Rails•! Data: •! Solr index of image metadata•! The user interface: •! jQuery Mobile – lightly customized css
  14. 14. Tools we used•! Serve images from Djatoka Image Server: •! 1st request: served on the fly by Djatoka (any size and crop) and cached locally by rails (slow) •! 2nd request: Apache serves image cached by rails (fast)
  15. 15. Lessons learned•! Exhibit designer hand selected the images for the mobile supplement.•! jQuery Mobile and Djatoka are very useful
  16. 16. Future plans•! Package rails app as an engine gem for re-use for future mobile supplements to exhibits•! Build an admin interface so exhibit designer can manage themes and associated images
