+All data resources will be [emitterified](https://github.com/utilise/utilise#--emitterify):
 
 ```js
-ripple('data').on('change', fn)
-ripple('data').once('change', fn)
-ripple('data').emit('change')
+// instead of: ripple.on('change', function(name, change){ .. })
+ripple('name').on('change', function(change){ .. })
+ripple('name').once('change', function(change){ .. })
+ripple('name').emit('change')
+```
+
+All data resources will be initialised with [versioning info](https://github.com/utilise/utilise#--set):
