How It Should Be
Data Sources Server Service Devices
Content Provider Content Consumer
How It Should Be
• Clear separation of concerns• Data• Service• Consumption Device
• Device Agnostic
• Requires well thought out architecture and API• Non-trivial effort
Common SLG Scenario
Data Sources Server Devices
Content Provider Content Consumer
Web Site
• This scenario is not limited to SLG, smaller organizations do not have budget to build out a more web-aware SOA system.
Many SLG Public Sector Scenarios
• Virtually every locality has a web site• Few have a fully built out web-rich SOA architecture
• Access to content is via browser• Non-native experience• Website may not be optimized for mobile• Less than perfect experience
• There “no app for that”• No app means they are not on our platform
• Missed opportunities• For Citizens• For Governments

Definition File
Cloud
Definitions Change the Game
Definition files make a screen scraping solution:
• Resilient to change• Changing definition file hosted in the cloud would not require
changes to the app
• Viable• Increased resilience and flexibility
• Use developer friendly formats: • XML (WinRT, WP7, & .NET)• JSON (WinRT)
