Code Systems contain all the relevant concepts that can be utilized to create Value Sets.
Besides supporting national and international Terminology Standards, such as SNOMED CT, ICD-10, or LOINC, Snowray also supports the creation and maintenance of Custom Code Systems.
Users have the option to access Code Systems either from the Dashboard or the Resources Page. When starting out from the Dashboard, clicking the resource card will automatically take users to the Overview tab of the Code System. In case of approaching from the Resources page, pressing the resource title will result in the same, while double-clicking the row will open the Content tab. Once on the Content tab, users have access to the Code System hierarchy and browsing of the terminology itself can immediately begin.
Clicking the small triangles next to the parent concepts enables users to search for concepts by expanding the tree. Besides this aforementioned manual approach, another option offers to use the filter search for lexical matches.
Search results can be examined in a list or a tree view.
In addition to the filter search, Snowray also provides an advanced search option for certain Code Systems (SNOMED CT and Custom Code Systems).
When browsing a Code System, selecting a concept navigates users to the concept details. On the concept's Overview tab descriptions, properties, and metadata are revealed. Some of the content is displayed in blue color, which indicates that it is a link to another concept. Clicking on those links navigates users to the linked concept's detailed overview.
The concept's History tab displays the changes made to the selected concept. Each change is represented on a timeline and has an individual node. In their title, the nodes display the name of the user who did the modification and the elapsed time since the change, while the action that modified the concept can be found in the details part.
Snowray's quick link feature enables users to take a look at specific concepts of a Code System without interrupting their browsing or searching flow.
Switching to a translation will change the terminology content to be displayed in the selected language within the terminology tree.
Additionally, when selected in the hierarchy, concepts will be displayed in the preferred language in the concept Overview tab header as well.
The language selector is accessible from the terminology tree, therefore, users can also change the display language of the terminology tree content when referenced in other resources, i.e. when serving as domains for Value Sets and Concept Maps.
To switch between the views, click on the icon, and select the corresponding option from the menu.
When hovering over concepts in the terminology tree, the icon representing the Open in new tab option will appear.
If you press , you will be taken to a new browser tab with the selected concept opened in the given Code System's Content tab.
The icon displayed in the terminology tree header enables changing the display language in case of terminologies with multiple translations.
To see the available languages, click on the icon. The alternatives will be displayed in a dropdown.
When selecting a translation other than the default language, the icon will turn blue, indicating that you are browsing content in another language.
