Specifying members of a reference set can be done in different ways. It will depend on the requirements for the reference set what approach is feasible and possible. Please refer to the Practical Guide to Reference Sets for detailed instructions on the approaches and methods for identifying the SNOMED CT components that will be referenced by the members of the reference set.
However, each reference set member will be represented in the reference set in accordance with the following principles and process.
Reference set members may be added to reference sets belonging to modules in
Reference set members created in the extension should be created within the module of the extension producer, so that it is possible to distinguish the reference set members created within the producers extension from reference set members created by other organisations (i.e. belonging to other modules).
Even though the individual reference set members belong to the module of the extension producer, the actual components that are referenced by the reference set member, may belong to modules in
The table below provides a summary of the process to follow when adding members to a reference set.
A new refset row is created with a unique id. The data type for this id is UUID and the id can be generated using a UUID generator. Note that a namespace identifier will not be part of this id.
Versioning and module identification attributes are set accordingly:
Attributes common for all reference set types are set accordingly:
|Attributes specific to the reference set type are set. For more information, please refer to the release file specification.|
