Things like JSON formatting and distance calculation are all done for you. PorPOISe XML files and SQL databases as data stores. Supported Layar features include:  1D (point), 2D (image) and 3D (model) objects  Custom actions  Custom filters (requires some PHP skills)  User authentication and personal layers (requires some more PHP and web development skills)

Setup config file Open config/config.xml: Setup the user: <developer-id>espozi</developer-id> <developer-key>Layar doesn't use a developer key anymore</developer-key> Create an empty Layer: DDiMIT XML layer configuration <layer> <name>ddimitdemo</name> <connector>XMLPOIConnector</connector> <source>ddimitdemo.xml</source> </layer>
  19. 19. Add an empty layer XML ddimitdemo.xml <?xml version="1.0" encoding="UTF-8"?> <layer> <pois> </pois> </layer>
  20. 20. Sign on to Dashboard
  21. 21. Test the layer
  22. 22. Your turn
  23. 23. Create dev accounts • Create an account on, then • Then I will give you permission to the DDiMIT layer
  24. 24. Create POIs • Goto • Sign in as admin (ask me for password) – Not sure if multiple users can add POIs concurrently, but let’s try it • Create your POIs by clicking “New POI”
  25. 25. Test the Layer • Using the web • Using your phone: – Download the Layar browser to your iPhone/Android – Login as your user – Click “Layers” -> “Test”
