Authoring

To enter editing mode and access functionalities related to authoring, click on the button in the upper right corner of the selected Value Set's content page.

Add a New Clause

New clauses can be added by constructing a query expression supported by the domain Code System (in case of SNOMED CT, this is an ECL expression), after clicking on the area surrounded by an intermittent line under the Includes and Excludes sections.

Create a New Clause

While authoring, clauses highlight parts of the hierarchy with colors. These help identify which part of the hierarchy is included (green and/or normal gray), excluded (red), suggested (purple), or just displayed (light gray) for contextual information.

If selecting a concept from the terminology tree the clause that involves the concept will be highlighted.

Highlight Clauses

There are different ways to add clauses to a Value Set. For more information visit the following pages:

Optimize

As part of the authoring process, users also have the option to optimize their Value Sets. This feature simplifies Value Sets by replacing individual members with ECL expressions. For example, if all the children of a concept are added, it will reduce the clauses to a single clause using the following format: < parentId | FSN |.

To use this option, navigate to the specific Value Set and start editing. Press the button in the upper right corner and select the Optimize context menu option.
