Architecture

The diagram below shows a component & connector view of the implemented architecture. OSCAR instances are connected to the CDX infrastructure via the Oscar Bidirectional Interoperability Bus (OBIB).

The functionality required to interact with the OBIB is encapsulated in the OBIB Connector component which is made available as a Java archive (JAR). The OBIB connection is configured by means of two artifacts on the OSCAR server: an obibconnector properties file and an obibconnector keystore file (see deployment).

The OBIB Connector interfaces with the OBIB using a secured REST API that is provided by the interface engine MirthConnect. Several CDX Channels are deployed on MirthConnect to generate and receive CDX documents.

MirthConnect interfaces with the CDX infrastructure via secured SOAP interfaces. That connection is implemented in the CDX Connector component.
