The following page is to capture the discussion about the "Specialization" element for Device (and Device Definition).
Current JIRA Tickets
- FHIR-38057 - DeviceDefinition and Device should use same "specialization" modelMeeting adjourned early - due to lack of participates for the topics on hand.
- FHIR-38058 - Device specialization assumes a particular model of standards compliance
- FHIR-39084 - Change .specialization to .conformsTo
- FHIR-39242 - Change .specialization to .conformsTo. See ticket FHIR-39084
- FHIR-39053 - Ambiguity when to use .specialization and when .property element
- FHIR-38902 - Consistency between Device and DeviceDefintion resources

DeviceDefinition
Requires clarification for the DeviceDefinition.classification.type that previously included risk class. Risk class is now part of the conformsTo element.

Summary Table
| Option--> | Option #1 - Specialization → conformsTo | Option #2 - Specialization |
|---|---|---|
| Description | Change the name of the element to "conformsTo" | Keep name of element as "Specialization" and updates to the descriptions/comments |
| Discussion | This can be used for any standard (beyond 11073 where the name of the element originated). Need to assess the impact of changing the name for systems that have specialization in production | Used in production (re: 11073 implementation) Need additional examples of standards |
| Proposed changes | Device.conformsTo
DeviceDefinition.conformsTo
Clarify use of conformsTo versus property and DeviceDefinition.classification.type | Device.specialization Clarify use of specialization versus property Add DeviceDefinition.specialization
Clarify use of conformsTo versus property and DeviceDefinition.classification.type |
