Mobile Enhanced Digital Collections
19
Mobile Enhanced DCs
  • More than just a small screen version of an
    existing digital collection

20
Mobile Enhanced DCs
  • More than just a small screen version of an
    existing digital collection
  • Leverages emerging mobile technology to create
    new and improved interfaces to digital collections

Mobile Enhanced DCs
  • More than just a small screen version of an
    existing digital collection
  • Leverages emerging mobile technology to create
    new and improved interfaces to digital
    collections
  • Reduce the disconnect between user and object
    brought about by digitization

22
Two Basic Technologies
  • Touch-based Interfaces
  • Geotagging Geolocation

23
Touch-based Interfaces
  • Swipe gesture
  • Interact directly with digital objects
  • Example Classics

The WolfWalk Project
31
WolfWalk in a Nutshell
  • Our first attempt to create a geomobile digital
    collection
  • Images sourced from university archives
    collection
  • iPhone app to be released Fall 2009

Content Workflow
  • Select sites to be included
  • Select images from existing digital image
    collection to represent sites
  • Author site descriptions
  • Author image descriptions
  • Enter content in database
  • Generate image derivatives

44
Technology
  • WolfWalk Database (MySQL)
  • WolfWalk Data Service (PHP/XHTML)
  • iPhone OS 3.0 (Objective-C)
  • MapKit Framework (Google Maps)
  • CoreLocation Framework (geolocation)

Lessons Learned
  • Not easy to repurpose existing image metadata
    (dates, descriptions)

47
Lessons Learned
  • Not easy to repurpose existing image metadata
    (dates, descriptions)
  • Mobile application development is different from
    website development (installed vs. networked
    content)
