A method of sharing data between wired properties associated with disparate data types includes receiving a first specification for dividing data items having a first data type published by an output property of a first service task into a first set of sub-units and a second specification for dividing data items having a second data type consumed an input property of a second service task into a second set of sub-units; receiving transformation logic for transforming data items divided into the first set of sub-units to data items divided into the second set of sub-units; dividing a first data item published by the output property into the first set of sub-units; applying the transformation logic to transform the divided first item to a second data item divided into the second set of sub-units; and joining the divided second data item. The service tasks are registered with an aggregation application that includes a wire between the properties.
