Identifier

The Identifier FHIR resource maps to the Identifier object in Salesforce.

FHIR V4.0 - Clinical Data Model Mapping

Here’s how the fields defined by FHIR for Identifier map to the fields in Salesforce.

Table 1. Identifier - Salesforce
Identifier Resource	Salesforce Field	Type	Salesforce Cardinality	Notes
`use`	`Identifier.IdUsageType`	Picklist	0.1	FHIR defines `identifier.use` as a code set. However, the Salesforce implementation of `Identifier.IdUsageType` is a dynamic picklist because of the limited list of possible values.
`type`	`Identifier.IdTypeId`	Polymorphic Lookup: `CodeSet`, `CodeSetBundle`	0.1	N/A
`system`	`Identifier.SourceSystem`	String	0.1	FHIR defines `identifier.system` as a URI. However, the Salesforce implementation of `Identifier.SourceSystem` is a string because Salesforce doesn’t support the URI data type.
`value`	`Identifier.IdValue`	String	0.1	N/A
`period`	`Identifier.EffectiveDate`	DateTime	0.1	In Salesforce’s implementation, `identifier.period` is split into two fields, `Identifier.EffectiveDate` and `Identifier.EndDate`.
`period`	`Identifier.EndDate`	DateTime	0.1
`assigner`	`Identifier.IssuingAuthorityId`	Lookup: `Account`	0.1	N/A
