> h3. Scenarios
> *Case 1*
> In a situation where, data exported from a cluster is imported to a different
> cluster, it is necessary to make changes to attributes of entities such that
> their values represent their environment
> Example: Entities exported from cluster called _'cl1'_ will have _@cl1_ in
> their qualifiedName attribute. When these entities are imported to a cluster
> called _'cl2'_ the qualifiedName attribute should read _@cl2_ to correctly
> reflect their new environment.
> *Case 2*
> Exported data contains an attribute that has value that does not conform to
> the conventions followed within the cluster. This can be corrected by
> exporting the data and reimporting it with an applied transform.
> Example: Entities were created with an attribute value as upper case, this
> needs to be lower case to conform to a convention.
> h3. Solution
> As part of Import API, it will help to be able to specify in a generic manner
> the transforms that could be applied to an entity type.
> The implementation should be extensible so that new transforms could be added
> in future.
