HL7 Standards Available Across All Releases

The HL7 standard is a set of EDI and XML messages designed to interchange information between healthcare providers. It is maintained by Health Level Seven, Inc., under the umbrella of the American National Standards Institute (ANSI). (DataDirect Technologies is an HL7 benefactor.)

DataDirect XML Converters™ supports the currently electronically published versions of the HL7 standard, across all messages and events, from HL7 2.0 to HL7 2.6. All of these versions are supported by both the Java and the .Net (C#) versions of the DataDirect XML Converters.

This grid shows exactly which messages the HL7 standard supports for each release.

For more information, read our tutorial entitled Converting from HL7 2.x to HL7 3.x.
