Efficient transformation of information between a source schema and a target schema
A method is described for relaying information from a first body of information defined by a source schema to a second body of information defined by a target schema. The method involves mapping content associated with one or more source schema fields from the first body of information to a third body of information defined by an intermediate schema. The method further involves executing one or more transformation functions that use the content and are identified by the intermediate schema. The method further involves mapping one or more results of the executing from the third body of information to the second body of information.
