There are multiple panels related to terminology.

It is also possible to initiate a Terminology Report to check the terminologies used in a project. This can be done from the Development Panel.

Terminology Identifiers Panel

The Terminology Identifiers Panel provides an overview of Value Set and Code System versions, sortable by their full identifier.


The search bar 1 can be used to filter the artefacts by ID, display name or version label.

Terminology Associations Panel

The Terminology Mappings Panel is used to associate a Concept in a dataset or a Transaction with a Coded Concept or Value Set.


The Navigation Bar on the left 1 offers a Datasets and Scenarios tab.

For managing Dataset Concept Associations, the relevant Dataset should be selected from the dropdown menu. For managing Transaction specific associations, both the Scenario and Transaction have to be selected. Thereafter the concepts are shown in a hierarchical tree.

When a concept is selected, the details are shown in the Detail Card on the right 2.

Associations with a Coded Concept

The CODE button 3 allows adding the association manually.

The SEARCH button 4 navigates to the Terminology Browser. The browser can be used to find a Coded Concept and associate it with the Dataset Concept in scope.

Associations with a Value Set

The ADD button 5 offers a dialog where a Value Set can be selected.

Hover the Speed Dial Menu 6 to edit or remove an association.

Associations with codes from a Value Set

Value Set code associations are currently readonly.

Transaction specific associations


Transaction specific associations are marked with an orange movie icon. The associations that are overwritten are strike-through emphasized. Overwritten associations can be restored. The action is available under the Speed Dial Menu. This will remove all transaction specific associations!

Terminology Browser

The Terminology Browser is used for browsing Code Systems.


When opening the Terminology Browser, the available Code Systems are listed 1.

The Browser offers a combined search field 2, where you can switch between searching a term or searching a code. The search mode can be changed by clicking on the icon.


The search field now uses debounce/throttle techniques to initiate the search upon user input. An owl is placed right to the search field to inform about search strategies and options.

General Search hints

To find terms you can combine exact match and wildcards search. If you type in something, hit 'enter' to search or wait for approximately 1.5 sec to let the search start automatically.

Lower case letters will also find terms with upper case letters.

Results are sorted by the word length of the respective term found.

Starting a search term with lower case will perform a wildcard search and require a minimum of **four **keystrokes.

Search TermFinds what?
salbfinds Salbutamol
pneufinds Pneumonia
acu astfinds Acute asthma
med revfinds Medication review
pa lo bafinds Pain lower back
ox ta 10finds Oxazepam tablets 10mg
hae Afinds Haemoglobin A

Starting a search term with upper case will perform an exact match search and requires a minimum of two keystrokes.

Search TermFinds what?
Hbfinds Hb (Hemoglobin), note the exact search
FH asfinds FH: Asthma (Family history: Asthma), note the combination of exact search and wildcard search

This text is also shown by the owl:


If you are interested in further information on how search and find terms, please have a look at a presentation by Dr Jeremy Rogers, Principal Terminology Specialist at the UK Terminology Centre (NHS Connecting for Health): Browsing SNOMED CT : Finding Terms (PDFopen in new window), he gave at the IHTSDO I&I SIG in November 2011.

Special LOINC search filter

There are different type of LOINC codes:

  • The LOINC codes with fully-specified names
  • The LOINC PART codes (LP), the atomic elements that comprise a fully-specified LOINC name.
  • Answer lists codes (LL), and answer string codes(LA).

If LOINC is selected as the only code system a filter symbol occurs that allow you to select the type of LOINC codes you want to see.

Search results


The search results are shown in the top level result table 1, concepts can be selected. The details of the selected Coded Concept are shown in the Concept Detail Part after the result table 2. The Concept Detail Part is able to show the hierarchy or the network of the Coded Concepts. Parents of the selected Coded Concept are listed above the Concept in Focus 3, the children of the selected Coded Concept are listed below 4.
