The TerminologyExtension class may be used to define sponsor-defined extensions to extensible ARS terminology. In the ARS modelModel, controlled terminology is implemented through the use of enumerations, each of which specifies a static set of valid values. It Although it is not possible for sponsors to modify enumerations to add additional values but , there are 4 "extensible" enumerations where a sponsor-defined term terms may be used instead of one 1 of the terms in the enumeration:
| Enumeration Name | Enumeration Description | Used In |
|---|
| AnalysisReasonEnum | The rationale for performing this analysis. It indicates when the analysis was planned. | Analysis |
| AnalysisPurposeEnum | The purpose of the analysis within the body of evidence (e.g., section in the clinical study reportCSR). | Analysis |
| OperationRoleEnum | The role that the referenced operation's result plays in the calculation of the result of this operation. | Operation |
| OutputFileTypeEnum | The file format of the file containing output from analyses. | Output |
In situations where a sponsor needs to use a sponsor-defined term instead of one 1 of the defined set of controlled terms, a terminology extension is created. A terminology extension is a set of one 1 or more sponsor-defined terms created to be used instead of the controlled terms defined for one of the " extensible " enumerations.

When needed, a single terminology extension may be created for any of the 4 extensible enumerations, and each terminology extension may contain one 1 or more sponsor terms. The enumeration attribute of the terminology extension indicates the name of the enumeration for which the terminology extension is being created, an identifier value for the terminology extension is specified in the id attribute, and one 1 or more sponsor terms are defined in the sponsorTerms attribute, each as an instance of the SponsorTerm class. Each sponsor term has the value to be used when represented for representation in a submission (in the submissionValue attribute), corresponding descriptive text (in the description attribute) and an assigned identifier value (in the id attribute).
| Tip |
|---|
The enumerations defined in the ARS model Model are considered to be CDISC controlled terminology so existing Controlled Terminology. Existing guidance should be followed when assigning sponsor terms for extensible enumerations. This includes, for example, guidance indicating that sponsor terms should not be synonyms for existing controlled terms. |

Sponsor terms that have been defined in a terminology extension are referenced through use of an enumeration-specific specialization of the ExtensibleTerminologyTerm class, as described in the ExtensibleTerminologyTerm section.
