The authors develop and study the concept of dataflow process networks as used for example by Kahn to suit exact computation over data types related to real numbers, such as continuous functions and geometrical solids. Furthermore, they consider communicating these exact objects among processes using protocols of a query-answer nature as introduced in their earlier paper. This enables processes to provide valid approximations with certain accuracy and focusing on certain locality as demanded by the receiving processes through queries.
