Conditional Configuration Framework -

-

i'm searching configuration framework handles key/values pairs based on conditions. language , storage type doesn't matter.

example background color application xyz:

  • application has background color "red".
  • on monday background color should green.
  • the background color user xyz on monday should orange.

the developer ask "application.background.color" , should return correct value based on given conditions.

in java, have @ commons configuration. need extend somewhat, should able use existing frameworks variable expansion, providing can define available context elements in advance.
