Level 1: dcis-libraries

These are the libraries with common functionalities for all SCSes. The libraries are the clients. They are responsible for the asynchronous data transfer of the data between the systems. So they will basically receive the data from the leading SCS via messaging and provide a default handler to retrieve the data. There is a second library for a default JPA implementation to keep the data. Every SCS has to decide if keeping the default data for the domain is fine or if it needs to implement the handler interface itself.
