This section describes derivatives that are specified by and distributed as part of SNOMED CT. Derivatives are artifacts which are either required or useful to support some aspect of SNOMED CT enabled implementation. These artifacts are known as derivatives because they are derived from SNOMED CT Components and either add properties to them or specify sets of related components. All SNOMED CT enabled applications need to support some derivatives.
The set of derivatives that need to be supported by an implementation depend on user requirements for particular types of functionality. Important aspects of functionality that require support for relevant derivatives include:
