About NextGen Connect

Mirth Connect, from NextGen Healthcare, is an integration engine for healthcare data. The README likens it to an interpreter: when a foreign system sends a message, Connect translates the message standard into the one your own system understands. Project topics point to HL7 and interoperability, and the software is written in Java.

Its message processing steps include filtering, which reads message parameters and decides whether a message continues to transformation, transformation, which converts one standard to another such as HL7 to XML, extraction, which can pull data from and push data to a database, and routing to the appropriate destination systems. These steps let organizations connect applications that use different formats.

The README covers useful links to downloads, a user guide, a wiki with an FAQ, forums and a Slack channel, followed by sections on installation, upgrading, starting the server and running on Java 9 or later. It includes a Java licensing note and a license section. The latest release listed is 4.5.2, and NextGen frames the product as supporting everything from small practices to large health information exchanges.
