easier to repurpose and reuse

13. Tools we used
•! Web App:
•! Ruby on Rails
•! Data:
•! Solr index of image
metadata
•! The user interface:
•! jQuery Mobile – lightly
customized css

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. Lessons learned
•! Exhibit designer hand selected the
images for the mobile supplement.
•! jQuery Mobile and Djatoka are very
useful

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
