A simple Erlang API for handling DDS data types and Quality of Service parameters

The choice of the programming language impacts the efficiency of the application and the robustness of the code. The characteristics of Erlang as a functional programming language supported distributed real time computing allowed us to propose eDDS: an Erlang based middleware compliant to the Data Distribution Service (DDS) standard that providing a strong Quality of Service (QoS) support. When the performance and the compliance to the norm have been easy achieved in particular on defining and setting QoS parameters, the lack of efficient and user-friendly support for data type management has been noticed. In this paper, we will explain this type checking problem and how we solved it.
