[์˜๋ฌธ]This study was initiated to develop eXtensible Markup Language (XML) module for Arden Markup Language which can be used in Clinical Decision Support System (CDSS). Arden Syntax was chosen as the HL7 standard language because of the advantages such as information sharing and reusability. But, at the same time, it also has problems such as Curly Brace problem and problem of requiring additional compiler. Development of Arden Syntax compiler not only requires a lot of time and efforts, but also requires reorganization of existing systems according to the Medical Logic Module. This is also an erroneous process.There were several structural differences in three approaches: Arden Syntax is Category; ArdenML is Tag; and Visual Basic is Comment, Function, Events, Class, and Procedure. XSLT was developed by analyzing three approaches. Based on XSLT, ArdenML was translated into Visual Basic and the interface module was developed to allow communicating with legacy systems.In this study, we verified that ArdenML can effectively used in developing CDSS by developing the hypertension Medical Logic Module with clinical rules on hypertension and developing interface and XSLT that is capable of translating to various systems using widely used general-purpose computer languages (such as VB, C#, JAVA). Most of the CDSS are independently developed and run, and therefore they require re-entry of rules, but this system makes it easier to interface with the existing systems simply by translating or compiling rules. This enhances development efforts to Rule Based CDSS.ope
