In many organisations a lot of commonality and crossover of data terms will inevitably exist across many applications. The ability to create a common overlay vocabulary to create once and apply to many applications reduces the effort to both prepare and maintain this. If a vocabulary exists in an application, the ability to export this and apply it to other applications should be extended, to include report generation showing those terms where no corresponding field/master item/value matched in the target application, to allow for verification and auditing. Alternatively a shared vocabulary definable for applications to make use of could be employed, in addition to keeping each application's specific vocabulary to complement this.
