The Guideline Interchange Format (GLIF) is a language for structured representation of guidelines. It was developed to facilitate sharing clinical guidelines. GLIF version 2 enabled modeling a guideline as a flowchart of structured steps, representing clinical actions and decisions. However, the attributes of structured constructs were defined as text strings that could not be parsed, and such guidelines could not be used for computer-based execution that requires automatic inference. GLIF3 is a new version of GLIF designed to support computer-based execution. GLIF3 builds upon the framework set by GLIF2 but augments it by introducing several new constructs and extending GLIF2 constructs to allow a more formal definition of decision criteria, action specifications and patient data. GLIF3 enables guideline encoding at three levels: a conceptual flowchart, a computable specification that can be verified for logical consistency and completeness, and an implementable specification that can be incorporated into particular institutional information systems.
指南交换格式（GLIF）是一种用于结构化表示指南的语言。它的开发旨在促进临床指南的共享。GLIF版本2能够将指南建模为结构化步骤的流程图，代表临床行动和决策。然而，结构化结构的属性被定义为无法解析的文本字符串，并且这样的指南不能用于需要自动推理的基于计算机的执行。GLIF3是GLIF的新版本，旨在支持基于计算机的执行。GLIF3建立在GLIF2设定的框架之上，但通过引入几个新结构并扩展GLIF2结构来增强它，以允许对决策标准、行动规范和患者数据进行更正式的定义。GLIF3支持在三个层面进行指南编码：概念流程图、可针对逻辑一致性和完整性进行验证的可计算规范，以及可纳入特定机构信息系统的可实施规范。
