Abstract: The Guideline Interchange Format (GLIF) defines primitive steps such as those for actions and decisions in the specification of guidelines as flowcharts. Modeling of guidelines using only primitives has several limitations including difficulties in authoring, variable specification of guidelines, and development of visually complex guidelines. Version 3 of GLIF (GLIF3) introduces a new construct called “macro”. A macro is a scalable approach for representing domain-level concepts. A macro allows mapping of a domain concept to a flowchart of GLIF steps thus enabling declarative specification of a procedural pattern. We analyzed guidelines to extract patterns of domain concepts from different types of guidelines. The patterns were used to design macros for these types of guidelines. Preliminary testing of authoring guidelines indicates that macros provide expressive-ness required for complete and accurate representation of the designated portions of the guideline algorithm.
