User-defined publication properties
In addition to system-defined publication properties, you can add your own name/value pairs. These are referred to as user-defined publication properties.
New user-defined publication properties can simply be added to the publication configuration. In this example, a "useIndexedDBDataLayer" property has been added:
On publish, the names and values of these properties are written to the "application.xml" file which makes them available to your runtime application. You can then access the property settings in JavaScript:
$.udb.settings.get( "*property-name*" )
Example
$.udb.settings.get( "StartPage" )
