TCP/IP HL7 Adapter Components

The TCP/IP HL7 Adapter incorporates three components:

• The HL7 TCP/IP Resource Adapter that implements the lower layer HL7 protocol over TCP/IP.

• Default inbound and outbound Collaborations that implement the HL7 messaging protocol, sequence numbering, and recourse actions.

• Generic HL7 Message Libraries that provide the structures necessary to parse and create the data messages and ACKs used by the protocol.

The TCP/IP HL7 Message Library, also known as an Object Type Definition (OTD) Library, enables the creation of HL7 interfaces capable of running over TCP/IP, and also utilizes the common Adapter services available in Java CAPS. The TCP/IP HL7 Adapter works hand in hand with the Sun Java CAPS HL7 Message Libraries, versions 2.1 through 2.5.1.

The TCP/IP HL7 Adapter properties allow the user to easily configure the operation of the TCP/IP HL7 Adapter. The Adapter includes a set of properties that are configured in the Connectivity Map and only apply to that Adapter in the Project. It also includes a set of properties that are configured in the Environment and apply to all TCP/IP HL7 Adapters in the Project. These properties are adopted into the Message Library’s functions.

The Message Library handles all of the lower-layer protocol. The Message Library’s behavior is customized using the Adapter configuration properties. These Adapter properties are used by the resource adapter, but are also accessed and used by the prebuilt Collaborations.
