 These RSE Hubs can take the form of, \eg{} full RSE units, smaller RSE groups, Open Source Program Offices (OSPOs), virtually across multiple units or combined under single leadership,
  depending on the environment of the hosting research organisation.
 All of these implementations are considered, taking into account the large variety of research environments in Germany which include not only universities, but also research consortia and other research performing organisations.
+We use the term central \emph{RSE unit} interchangeably with the term \emph{RSE hub} even though for large federated research organisations there might be a more complex arrangement such as a network of RSE hubs.
