Successfully balloted by Health Level Seven (HL7) International, the latest Arden Syntax version contains a new feature: ArdenML, an XML representation of Arden Syntax’s medical logic modules (MLMs). Medexter Healthcare offers cross compilation/transformation between the text-based and the XML-based representations of the Arden Syntax MLMs. Thus, Arden Syntax is now compatible with all other HL7 standards based on XML (HL7 version 3, VmR, and others). As a further benefit, it is now possible for developers to use available XML tools in their work with MLMs.
