Navigating topic maps on a mobile device
• Visible information has to be reduced to a minimum
• Existing viewers like Omnigator and Maiana display lots of information on their main page that is rarely used as an entry point for navigation (role types, name type, occurrence types)
• "Topic map Metadata", "Browse By Type", "Browse By Name"
• From a topic page the user can navigate to other topic pages via associations

Displaying topic labels
• Find the default name
• Find a name with the fewest scoping topics
• Find a subject identifier, subject locator, item identifier

Issues
• Memory usage is hard to control
• Script execution timeouts occur
• jQTouch maybe not the best choice
• PSIs are not meant for mobile devices
